Detailed Description

A collection of billboards (faces which are always facing the given direction) with the same (default) dimensions, material and which are fairly close proximity to each other.

Remarks: Billboards are rectangles made up of 2 tris which are always facing the given direction. They are typically used for special effects like particles. This class collects together a set of billboards with the same (default) dimensions, material and relative locality in order to process them more efficiently. The entire set of billboards will be culled as a whole (by default, although this can be changed if you want a large set of billboards which are spread out and you want them culled individually), individual Billboards have locations which are relative to the set (which itself derives it's position from the SceneNode it is attached to since it is a MoveableObject), they will be rendered as a single rendering operation, and some calculations will be sped up by the fact that they use the same dimensions so some workings can be reused.

: A BillboardSet can be created using the SceneManager::createBillboardSet method. They can also be used internally by other classes to create effects.

Note: Billboard bounds are only automatically calculated when you create them. If you modify the position of a billboard you may need to call _updateBounds if the billboard moves outside the original bounds. Similarly, the bounds do no shrink when you remove a billboard, if you want them to call _updateBounds, but note this requires a potentially expensive examination of every billboard in the set.

Constructor & Destructor Documentation

◆ BillboardSet()

Ogre::BillboardSet::BillboardSet	(	const String &	name,
		unsigned int	poolSize = `20`,
		bool	externalDataSource = `false`
	)

Usual constructor - this is called by the SceneManager.

Parameters

name	The name to give the billboard set (must be unique)
poolSize	The initial size of the billboard pool. Estimate of the number of billboards which will be required, and pass it using this parameter. The set will preallocate this number to avoid memory fragmentation. The default behaviour once this pool has run out is to double it.
externalDataSource	If `true`, the source of data for drawing the billboards will not be the internal billboard list, but external data. When driving the billboard from external data, you must call _notifyCurrentCamera to reorient the billboards, setPoolSize to set the maximum billboards you want to use, beginBillboards to start the update, and injectBillboard per billboard, followed by endBillboards.

Member Function Documentation

◆ createBillboard() [1/2]

Billboard* Ogre::BillboardSet::createBillboard	(	const Vector3 &	position,
		const ColourValue &	colour = `ColourValue::White`
	)

Creates a new billboard and adds it to this set.

Remarks: Behaviour once the billboard pool has been exhausted depends on the BillboardSet::setAutoextend option.

Parameters

position	The position of the new billboard realtive to the certer of the set
colour	Optional base colour of the billboard.

Returns: On success, a pointer to a newly created Billboard is returned.

: On failure (i.e. no more space and can't autoextend), NULL is returned.

See also: BillboardSet::setAutoextend

◆ createBillboard() [2/2]

Billboard* Ogre::BillboardSet::createBillboard	(	Real	x,
		Real	y,
		Real	z,
		const ColourValue &	colour = `ColourValue::White`
	)

Creates a new billboard and adds it to this set.

Remarks: Behaviour once the billboard pool has been exhausted depends on the BillboardSet::setAutoextend option.

Parameters

x	The `x` position of the new billboard relative to the center of the set
y	The `y` position of the new billboard relative to the center of the set
z	The `z` position of the new billboard relative to the center of the set
colour	Optional base colour of the billboard.

Returns: On success, a pointer to a newly created Billboard is returned.

: On failure (i.e. no more space and can't autoextend), NULL is returned.

See also: BillboardSet::setAutoextend

◆ getNumBillboards()

virtual int Ogre::BillboardSet::getNumBillboards ( void ) const

virtual

Returns the number of active billboards which currently make up this set.

◆ setAutoextend()

virtual void Ogre::BillboardSet::setAutoextend ( bool autoextend )

virtual

Tells the set whether to allow automatic extension of the pool of billboards.

Remarks: A BillboardSet stores a pool of pre-constructed billboards which are used as needed when a new billboard is requested. This allows applications to create / remove billboards efficiently without incurring construction / destruction costs (a must for sets with lots of billboards like particle effects). This method allows you to configure the behaviour when a new billboard is requested but the billboard pool has been exhausted.

: The default behaviour is to allow the pool to extend (typically this allocates double the current pool of billboards when the pool is expended), equivalent to calling this method with autoExtend = true. If you set the parameter to false however, any attempt to create a new billboard when the pool has expired will simply fail silently, returning a null pointer.

Parameters

autoextend true to double the pool every time it runs out, false to fail silently.

◆ getAutoextend()

virtual bool Ogre::BillboardSet::getAutoextend ( void ) const

virtual

Returns true if the billboard pool automatically extends.

See also: BillboardSet::setAutoextend

◆ setSortingEnabled()

virtual void Ogre::BillboardSet::setSortingEnabled ( bool sortenable )

virtual

Enables sorting for this BillboardSet.

(default: off)

Parameters

sortenable true to sort the billboards according to their distance to the camera

◆ getSortingEnabled()

virtual bool Ogre::BillboardSet::getSortingEnabled ( void ) const

virtual

Returns true if sorting of billboards is enabled based on their distance from the camera.

See also: BillboardSet::setSortingEnabled

◆ setPoolSize()

virtual void Ogre::BillboardSet::setPoolSize ( size_t size )

virtual

Adjusts the size of the pool of billboards available in this set.

Remarks: See the BillboardSet::setAutoextend method for full details of the billboard pool. This method adjusts the preallocated size of the pool. If you try to reduce the size of the pool, the set has the option of ignoring you if too many billboards are already in use. Bear in mind that calling this method will incur significant construction / destruction calls so should be avoided in time-critical code. The same goes for auto-extension, try to avoid it by estimating the pool size correctly up-front.

Parameters

size	The new size for the pool.

◆ getPoolSize()

virtual unsigned int Ogre::BillboardSet::getPoolSize ( void ) const

virtual

Returns the current size of the billboard pool.

Returns: The current size of the billboard pool.

See also: BillboardSet::setAutoextend

◆ clear()

virtual void Ogre::BillboardSet::clear ( )

virtual

Empties this set of all billboards.

◆ getBillboard()

virtual Billboard* Ogre::BillboardSet::getBillboard ( unsigned int index ) const

virtual

Returns a pointer to the billboard at the supplied index.

Note: This method requires linear time since the billboard list is a linked list.

Parameters

index The index of the billboard that is requested.

Returns: On success, a valid pointer to the requested billboard is returned.

: On failure, NULL is returned.

◆ removeBillboard() [1/2]

virtual void Ogre::BillboardSet::removeBillboard ( unsigned int index )

virtual

Removes the billboard at the supplied index.

Note: This method requires linear time since the billboard list is a linked list.

◆ removeBillboard() [2/2]

virtual void Ogre::BillboardSet::removeBillboard ( Billboard * pBill )

virtual

Removes a billboard from the set.

Note: This version is more efficient than removing by index.

◆ setBillboardOrigin()

virtual void Ogre::BillboardSet::setBillboardOrigin ( BillboardOrigin origin )

virtual

Sets the point which acts as the origin point for all billboards in this set.

Remarks: This setting controls the fine tuning of where a billboard appears in relation to it's position. It could be that a billboard's position represents it's center (e.g. for fireballs), it could mean the center of the bottom edge (e.g. a tree which is positioned on the ground), the top-left corner (e.g. a cursor).

: The default setting is BBO_CENTER.

Parameters

origin A member of the BillboardOrigin enum specifying the origin for all the billboards in this set.

Referenced by Ogre::BillboardParticleRenderer::setBillboardOrigin().

◆ getBillboardOrigin()

virtual BillboardOrigin Ogre::BillboardSet::getBillboardOrigin ( void ) const

virtual

Gets the point which acts as the origin point for all billboards in this set.

Returns: A member of the BillboardOrigin enum specifying the origin for all the billboards in this set.

Referenced by Ogre::BillboardParticleRenderer::getBillboardOrigin().

◆ _notifyBillboardRotated()

virtual void Ogre::BillboardSet::_notifyBillboardRotated ( void )

virtual

Internal callback used by Billboards to notify their parent that they have been rotated.

◆ getCullIndividually()

virtual bool Ogre::BillboardSet::getCullIndividually ( void ) const

virtual

Returns whether or not billboards in this are tested individually for culling.

◆ setCullIndividually()

virtual void Ogre::BillboardSet::setCullIndividually ( bool cullIndividual )

virtual

Sets whether culling tests billboards in this individually as well as in a group.

Remarks: Billboard sets are always culled as a whole group, based on a bounding box which encloses all billboards in the set. For fairly localised sets, this is enough. However, you can optionally tell the set to also cull individual billboards in the set, i.e. to test each individual billboard before rendering. The default is not to do this.

: This is useful when you have a large, fairly distributed set of billboards, like maybe trees on a landscape. You probably still want to group them into more than one set (maybe one set per section of landscape), which will be culled coarsely, but you also want to cull the billboards individually because they are spread out. Whilst you could have lots of single-tree sets which are culled separately, this would be inefficient to render because each tree would be issued as it's own rendering operation.

: By calling this method with a parameter of true, you can have large billboard sets which are spaced out and so get the benefit of batch rendering and coarse culling, but also have fine-grained culling so unnecessary rendering is avoided.

Parameters

cullIndividual If true, each billboard is tested before being sent to the pipeline as well as the whole set having to pass the coarse group bounding test.

◆ setBillboardType()

virtual void Ogre::BillboardSet::setBillboardType ( BillboardType bbt )

virtual

Sets the type of billboard to render.

Remarks: The default sort of billboard (BBT_POINT), always has both x and y axes parallel to the camera's local axes. This is fine for 'point' style billboards (e.g. flares, smoke, anything which is symmetrical about a central point) but does not look good for billboards which have an orientation (e.g. an elongated raindrop). In this case, the oriented billboards are more suitable (BBT_ORIENTED_COMMON or BBT_ORIENTED_SELF) since they retain an independent Y axis and only the X axis is generated, perpendicular to both the local Y and the camera Z.

: In some case you might want the billboard has fixed Z axis and doesn't need to face to camera (e.g. an aureola around the player and parallel to the ground). You can use BBT_PERPENDICULAR_SELF which the billboard plane perpendicular to the billboard own direction. Or BBT_PERPENDICULAR_COMMON which the billboard plane perpendicular to the common direction.

Note: BBT_PERPENDICULAR_SELF and BBT_PERPENDICULAR_COMMON can't guarantee counterclockwise, you might use double-side material (cull_hardware node) to ensure no billboard are culled.

Parameters

bbt	The type of billboard to render

◆ getBillboardType()

virtual BillboardType Ogre::BillboardSet::getBillboardType ( void ) const

virtual

Returns the billboard type in use.

◆ setCommonDirection()

virtual void Ogre::BillboardSet::setCommonDirection ( const Vector3 & vec )

virtual

Use this to specify the common direction given to billboards of type BBT_ORIENTED_COMMON or BBT_PERPENDICULAR_COMMON.

Remarks: Use BBT_ORIENTED_COMMON when you want oriented billboards but you know they are always going to be oriented the same way (e.g. rain in calm weather). It is faster for the system to calculate the billboard vertices if they have a common direction.

: The common direction also use in BBT_PERPENDICULAR_COMMON, in this case the common direction treat as Z axis, and an additional common up-vector was use to determine billboard X and Y axis.

See also: setCommonUpVector

Parameters

vec	The direction for all billboards.

Note: The direction are use as is, never normalised in internal, user are supposed to normalise it himself.

◆ getCommonDirection()

virtual const Vector3& Ogre::BillboardSet::getCommonDirection ( void ) const

virtual

Gets the common direction for all billboards (BBT_ORIENTED_COMMON)

◆ setCommonUpVector()

virtual void Ogre::BillboardSet::setCommonUpVector ( const Vector3 & vec )

virtual

Use this to specify the common up-vector given to billboards of type BBT_PERPENDICULAR_SELF or BBT_PERPENDICULAR_COMMON.

Remarks: Use BBT_PERPENDICULAR_SELF or BBT_PERPENDICULAR_COMMON when you want oriented billboards perpendicular to specify direction vector (or, Z axis), and doesn't face to camera. In this case, we need an additional up-vector to determine the billboard X and Y axis. The generated billboard plane and X-axis guarantee perpendicular to specify direction.

See also: setCommonDirection

: The specify direction is billboard own direction when billboard type is BBT_PERPENDICULAR_SELF, and it's shared common direction when billboard type is BBT_PERPENDICULAR_COMMON.

Parameters

vec	The up-vector for all billboards.

Note: The up-vector are use as is, never normalised in internal, user are supposed to normalise it himself.

◆ getCommonUpVector()

virtual const Vector3& Ogre::BillboardSet::getCommonUpVector ( void ) const

virtual

Gets the common up-vector for all billboards (BBT_PERPENDICULAR_SELF and BBT_PERPENDICULAR_COMMON)

◆ setUseAccurateFacing()

virtual void Ogre::BillboardSet::setUseAccurateFacing ( bool acc )

inlinevirtual

Sets whether or not billboards should use an 'accurate' facing model based on the vector from each billboard to the camera, rather than an optimised version using just the camera direction.

Remarks: By default, the axes for all billboards are calculated using the camera's view direction, not the vector from the camera position to the billboard. The former is faster, and most of the time the difference is not noticeable. However for some purposes (e.g. very large, static billboards) the changing billboard orientation when rotating the camera can be off putting, therefore you can enable this option to use a more expensive, but more accurate version.

Parameters

acc	True to use the slower but more accurate model. Default is false.

◆ getUseAccurateFacing()

virtual bool Ogre::BillboardSet::getUseAccurateFacing ( void ) const

inlinevirtual

Gets whether or not billboards use an 'accurate' facing model based on the vector from each billboard to the camera, rather than an optimised version using just the camera direction.

◆ getLights()

const LightList& Ogre::BillboardSet::getLights ( void ) const

virtual

Gets a list of lights, ordered relative to how close they are to this renderable.

Remarks: Directional lights, which have no position, will always be first on this list.

Implements Ogre::Renderable.

◆ visitRenderables()

void Ogre::BillboardSet::visitRenderables	(	Renderable::Visitor *	visitor,
		bool	debugRenderables = `false`
	)

virtual

Method to allow a caller to abstractly iterate over the Renderable instances that this MovableObject will add to the render queue when asked, if any.

Parameters

visitor	Pointer to a class implementing the Renderable::Visitor interface which will be called back for each Renderable which will be queued. Bear in mind that the state of the Renderable instances may not be finalised depending on when you call this.
debugRenderables	If false, only regular renderables will be visited (those for normal display). If true, debug renderables will be included too.

Implements Ogre::MovableObject.

◆ _sortBillboards()

virtual void Ogre::BillboardSet::_sortBillboards ( Camera * cam )

virtual

Sort the billboard set.

Only called when enabled via setSortingEnabled

◆ _getSortMode()

virtual

Gets the sort mode of this billboard set.

◆ setBillboardsInWorldSpace()

virtual void Ogre::BillboardSet::setBillboardsInWorldSpace ( bool ws )

inlinevirtual

Sets whether billboards should be treated as being in world space.

Remarks: This is most useful when you are driving the billboard set from an external data source.

◆ getBillboardsInWorldSpace()

bool Ogre::BillboardSet::getBillboardsInWorldSpace ( )

inline

Gets whether billboards are treated as being in world space.

◆ setTextureCoords()

virtual void Ogre::BillboardSet::setTextureCoords	(	Ogre::FloatRect const *	coords,
		uint16	numCoords
	)

virtual

BillboardSet can use custom texture coordinates for various billboards.

This is useful for selecting one of many particle images out of a tiled texture sheet, or doing flipbook animation within a single texture.

: The generic functionality is setTextureCoords(), which will copy the texture coordinate rects you supply into internal storage for the billboard set. If your texture sheet is a square grid, you can also use setTextureStacksAndSlices() for more convenience, which will construct the set of texture coordinates for you.

: When a Billboard is created, it can be assigned a texture coordinate set from within the sets you specify (that set can also be re-specified later). When drawn, the billboard will use those texture coordinates, rather than the full 0-1 range.

Parameters

coords	is a vector of texture coordinates (in UV space) to choose from for each billboard created in the set.
numCoords	is how many such coordinate rectangles there are to choose from.

Remarks: Set 'coords' to 0 and/or 'numCoords' to 0 to reset the texture coord rects to the initial set of a single rectangle spanning 0 through 1 in both U and V (i e, the entire texture).

See also: BillboardSet::setTextureStacksAndSlices() Billboard::setTexcoordIndex()

◆ setTextureStacksAndSlices()

virtual void Ogre::BillboardSet::setTextureStacksAndSlices	(	uchar	stacks,
		uchar	slices
	)

virtual

setTextureStacksAndSlices() will generate texture coordinate rects as if the texture for the billboard set contained 'stacks' rows of 'slices' images each, all equal size.

Thus, if the texture size is 512x512 and 'stacks' is 4 and 'slices' is 8, each sub-rectangle of the texture would be 128 texels tall and 64 texels wide.

Remarks: This function is short-hand for creating a regular set and calling setTextureCoords() yourself. The numbering used for Billboard::setTexcoordIndex() counts first across, then down, so top-left is 0, the one to the right of that is 1, and the lower-right is stacks*slices-1.

See also: BillboardSet::setTextureCoords()

◆ getTextureCoords()

virtual Ogre::FloatRect const* Ogre::BillboardSet::getTextureCoords ( uint16 * oNumCoords )

virtual

getTextureCoords() returns the current texture coordinate rects in effect.

By default, there is only one texture coordinate rect in the set, spanning the entire texture from 0 through 1 in each direction.

See also: BillboardSet::setTextureCoords()

◆ setPointRenderingEnabled()

virtual void Ogre::BillboardSet::setPointRenderingEnabled ( bool enabled )

virtual

Set whether or not the BillboardSet will use point rendering rather than manually generated quads.

Remarks: By default a billboardset is rendered by generating geometry for a textured quad in memory, taking into account the size and orientation settings, and uploading it to the video card. The alternative is to use hardware point rendering, which means that only one position needs to be sent per billboard rather than 4 and the hardware sorts out how this is rendered based on the render state.

Using point rendering is faster than generating quads manually, but is more restrictive. The following restrictions apply:

Only the BBT_POINT type is supported
Size and appearance of each billboard is controlled by the material (Pass::setPointSize, Pass::setPointSizeAttenuation, Pass::setPointSpritesEnabled)
Per-billboard size is not supported (stems from the above)
Per-billboard rotation is not supported, this can only be controlled through texture unit rotation
Only BBO_CENTER origin is supported
Per-billboard texture coordinates are not supported

: You will almost certainly want to enable in your material pass both point attenuation and point sprites if you use this option.

Parameters

enabled True to enable point rendering, false otherwise

◆ isPointRenderingEnabled()

virtual bool Ogre::BillboardSet::isPointRenderingEnabled ( void ) const

inlinevirtual

Returns whether point rendering is enabled.

◆ getTypeFlags()

uint32 Ogre::BillboardSet::getTypeFlags ( void ) const

virtual

Override to return specific type flag.

Reimplemented from Ogre::MovableObject.

◆ setAutoUpdate()

void Ogre::BillboardSet::setAutoUpdate ( bool autoUpdate )

Set the auto update state of this billboard set.

Remarks: This methods controls the updating policy of the vertex buffer. By default auto update is true so the vertex buffer is being update every time this billboard set is about to be rendered. This behavior best fit when the billboards of this set changes frequently. When using static or semi-static billboards, it is recommended to set auto update to false. In that case one should call notifyBillboardDataChanged method to reflect changes made to the billboards data.

◆ getAutoUpdate()

bool Ogre::BillboardSet::getAutoUpdate ( void ) const

inline

Return the auto update state of this billboard set.

◆ notifyBillboardDataChanged()

void Ogre::BillboardSet::notifyBillboardDataChanged ( void )

inline

When billboard set is not auto updating its GPU buffer, the user is responsible to inform it about any billboard changes in order to reflect them at the rendering stage.

Calling this method will cause GPU buffers update in the next render queue update.

◆ _releaseManualHardwareResources()

void Ogre::BillboardSet::_releaseManualHardwareResources ( )

inlinevirtual

◆ getName()

const String& Ogre::MovableObject::getName ( void ) const

inlineinherited

Returns the name of this object.

◆ getParentNode()

Node* Ogre::MovableObject::getParentNode ( void ) const

inlineinherited

Returns the node to which this object is attached.

Remarks: A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. Both are Node subclasses so this method will return either.

◆ getParentSceneNode()

SceneNode* Ogre::MovableObject::getParentSceneNode ( void ) const

inherited

Returns the scene node to which this object is attached.

Remarks: A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. This method will return the scene node of the parent entity if the latter is true.

◆ isParentTagPoint()

bool Ogre::MovableObject::isParentTagPoint ( ) const

inlineinherited

Reimplemented in Ogre::Entity, and Ogre::PortalBase.

◆ setVisible()

void Ogre::MovableObject::setVisible ( bool visible )

inlineinherited

Tells this object whether to be visible or not, if it has a renderable component.

Note: An alternative approach of making an object invisible is to detach it from it's SceneNode, or to remove the SceneNode entirely. Detaching a node means that structurally the scene graph changes. Once this change has taken place, the objects / nodes that have been removed have less overhead to the visibility detection pass than simply making the object invisible, so if you do this and leave the objects out of the tree for a long time, it's faster. However, the act of detaching / reattaching nodes is in itself more expensive than setting an object visibility flag, since in the latter case structural changes are not made. Therefore, small or frequent visibility changes are best done using this method; large or more longer term changes are best done by detaching.

Referenced by Ogre::Light::setVisible().

◆ getVisible()

bool Ogre::MovableObject::getVisible ( void ) const

inlineinherited

Gets this object whether to be visible or not, if it has a renderable component.

Remarks: Returns the value set by MovableObject::setVisible only.

◆ isVisible()

virtualinherited

Returns whether or not this object is supposed to be visible or not.

Remarks: Takes into account both upper rendering distance and visible flag.

Reimplemented in Ogre::StaticGeometry::Region.

Referenced by Ogre::Frustum::isCustomProjectionMatrixEnabled().

◆ setRenderingDistance()

void Ogre::MovableObject::setRenderingDistance ( Real dist )

inlineinherited

Sets the distance at which the object is no longer rendered.

Note: Camera::setUseRenderingDistance() needs to be called for this parameter to be used.

Parameters

dist	Distance beyond which the object will not be rendered (the default is 0, which means objects are always rendered).

◆ getRenderingDistance()

Real Ogre::MovableObject::getRenderingDistance ( void ) const

inlineinherited

Gets the distance at which batches are no longer rendered.

◆ setRenderingMinPixelSize()

void Ogre::MovableObject::setRenderingMinPixelSize ( Real pixelSize )

inlineinherited

Sets the minimum pixel size an object needs to be in both screen axes in order to be rendered.

Note: Camera::setUseMinPixelSize() needs to be called for this parameter to be used.

Parameters

pixelSize Number of minimum pixels (the default is 0, which means objects are always rendered).

◆ getRenderingMinPixelSize()

Real Ogre::MovableObject::getRenderingMinPixelSize ( ) const

inlineinherited

Returns the minimum pixel size an object needs to be in both screen axes in order to be rendered.

◆ setUserAny() [1/2]

void Ogre::MovableObject::setUserAny ( const Any & anything )

inlineinherited

Deprecated:: use UserObjectBindings::setUserAny via getUserObjectBindings() instead.

Sets any kind of user value on this object.

Remarks: This method allows you to associate any user value you like with this MovableObject. This can be a pointer back to one of your own classes for instance.

You can use it to associate one or more custom objects with this class instance.

See also: UserObjectBindings::setUserAny.

◆ setRenderQueueGroup()

virtual void Ogre::MovableObject::setRenderQueueGroup ( uint8 queueID )

virtualinherited

Sets the render queue group this entity will be rendered through.

Remarks: Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to the default queue (RenderQueue::getDefaultQueueGroup), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.

: See RenderQueue for more details.

Parameters

queueID Enumerated value of the queue group to use. See the enum RenderQueueGroupID for what kind of values can be used here.

Reimplemented in Ogre::ParticleSystem, and Ogre::Entity.

◆ setRenderQueueGroupAndPriority()

virtual void Ogre::MovableObject::setRenderQueueGroupAndPriority	(	uint8	queueID,
		ushort	priority
	)

virtualinherited

Sets the render queue group and group priority this entity will be rendered through.

Remarks: Render queues are grouped to allow you to more tightly control the ordering of rendered objects. Within a single render group there another type of grouping called priority which allows further control. If you do not call this method, all Entity objects default to the default queue and priority (RenderQueue::getDefaultQueueGroup, RenderQueue::getDefaultRenderablePriority), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.

: See RenderQueue for more details.

Parameters

queueID	Enumerated value of the queue group to use. See the enum RenderQueueGroupID for what kind of values can be used here.
priority	The priority within a group to use.

Reimplemented in Ogre::ParticleSystem, and Ogre::Entity.

◆ getRenderQueueGroup()

Reimplemented in Ogre::InstancedEntity.

◆ setQueryFlags()

void Ogre::MovableObject::setQueryFlags ( uint32 flags )

inlineinherited

Sets the query flags for this object.

Remarks: When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

◆ addQueryFlags()

void Ogre::MovableObject::addQueryFlags ( uint32 flags )

inlineinherited

As setQueryFlags, except the flags passed as parameters are appended to the existing flags on this object.

inlinestaticinherited

Get the default query flags for all future MovableObject instances.

◆ setVisibilityFlags()

void Ogre::MovableObject::setVisibilityFlags ( uint32 flags )

inlineinherited

Sets the visibility flags for this object.

Remarks: As well as a simple true/false value for visibility (as seen in setVisible), you can also set visibility flags which when 'and'ed with the SceneManager's visibility mask can also make an object invisible.

◆ addVisibilityFlags()

void Ogre::MovableObject::addVisibilityFlags ( uint32 flags )

inlineinherited

As setVisibilityFlags, except the flags passed as parameters are appended to the existing flags on this object.

◆ removeVisibilityFlags()

void Ogre::MovableObject::removeVisibilityFlags ( uint32 flags )

◆ setListener()

void Ogre::MovableObject::setListener ( Listener * listener )

inlineinherited

Sets a listener for this object.

Remarks: Note for size and performance reasons only one listener per object is allowed.

◆ getListener()

Listener* Ogre::MovableObject::getListener ( void ) const

inlineinherited

Gets the current listener for this object.

◆ queryLights()

const LightList& Ogre::MovableObject::queryLights ( void ) const

inherited

Gets a list of lights, ordered relative to how close they are to this movable object.

Remarks: By default, this method gives the listener a chance to populate light list first, if there is no listener or Listener::objectQueryLights returns NULL, it'll query the light list from parent entity if it is present, or returns SceneNode::findLights if it has parent scene node, otherwise it just returns an empty list.

: The object internally caches the light list, so it will recalculate it only when object is moved, or lights that affect the frustum have been changed (

See also: SceneManager::_getLightsDirtyCounter), but if listener exists, it will be called each time, so the listener should implement their own cache mechanism to optimise performance.

: This method can be useful when implementing Renderable::getLights in case the renderable is a part of the movable.

Returns: The list of lights use to lighting this object.

◆ getLightMask()

uint32 Ogre::MovableObject::getLightMask ( ) const

inlineinherited

Get a bitwise mask which will filter the lights affecting this object.

Remarks: By default, this mask is fully set meaning all lights will affect this object

◆ setLightMask()

void Ogre::MovableObject::setLightMask ( uint32 lightMask )

inherited

Set a bitwise mask which will filter the lights affecting this object.

Remarks: This mask will be compared against the mask held against Light to determine if a light should affect a given object. By default, this mask is fully set meaning all lights will affect this object

◆ _getLightList()

LightList* Ogre::MovableObject::_getLightList ( )

inlineinherited

Returns a pointer to the current list of lights for this object.

Remarks: You should not modify this list outside of MovableObject::Listener::objectQueryLights (say if you want to use it to implement this method, and use the pointer as a return value) and for reading it's only accurate as at the last frame.

Implements Ogre::ShadowCaster.

Reimplemented in Ogre::StaticGeometry::Region.

◆ getLightCapBounds()

const AxisAlignedBox& Ogre::MovableObject::getLightCapBounds ( void ) const

virtualinherited

Overridden member from ShadowCaster.

Implements Ogre::ShadowCaster.

◆ getDarkCapBounds()

const AxisAlignedBox& Ogre::MovableObject::getDarkCapBounds	(	const Light &	light,
		Real	dirLightExtrusionDist
	)		const

virtualinherited

Overridden member from ShadowCaster.

Implements Ogre::ShadowCaster.

◆ setCastShadows()

void Ogre::MovableObject::setCastShadows ( bool enabled )

inlineinherited

Sets whether or not this object will cast shadows.

Remarks: This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.

Note: This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

◆ getCastShadows()

bool Ogre::MovableObject::getCastShadows ( void ) const

inlinevirtualinherited

Returns whether shadow casting is enabled for this object.

Implements Ogre::ShadowCaster.

◆ getReceivesShadows()

bool Ogre::MovableObject::getReceivesShadows ( )

inherited

Returns whether the Material of any Renderable that this MovableObject will add to the render queue will receive shadows.

◆ getPointExtrusionDistance()

Real Ogre::MovableObject::getPointExtrusionDistance ( const Light * l ) const

virtualinherited

Get the distance to extrude for a point/spot light.

Implements Ogre::ShadowCaster.

◆ setDebugDisplayEnabled()

void Ogre::MovableObject::setDebugDisplayEnabled ( bool enabled )

inlineinherited

Sets whether or not the debug display of this object is enabled.

Remarks: Some objects aren't visible themselves but it can be useful to display a debug representation of them. Or, objects may have an additional debug display on top of their regular display. This option enables / disables that debug display. Objects that are not visible never display debug geometry regardless of this setting.

◆ isDebugDisplayEnabled()

bool Ogre::MovableObject::isDebugDisplayEnabled ( void ) const

inlineinherited

Gets whether debug display of this object is enabled.

◆ clearShadowRenderableList()

static void Ogre::ShadowCaster::clearShadowRenderableList ( ShadowRenderableList & shadowRenderables )

staticinherited

Common implementation of releasing shadow renderables.

◆ extrudeVertices()

static void Ogre::ShadowCaster::extrudeVertices	(	const HardwareVertexBufferSharedPtr &	vertexBuffer,
		size_t	originalVertexCount,
		const Vector4 &	lightPos,
		Real	extrudeDist
	)

staticinherited

Utility method for extruding vertices based on a light.

Remarks: Unfortunately, because D3D cannot handle homogeneous (4D) position coordinates in the fixed-function pipeline (GL can, but we have to be cross-API), when we extrude in software we cannot extrude to infinity the way we do in the vertex program (by setting w to 0.0f). Therefore we extrude by a fixed distance, which may cause some problems with larger scenes. Luckily better hardware (ie vertex programs) can fix this.

Parameters

vertexBuffer	The vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
originalVertexCount	The count of the original number of vertices, i.e. the number in the mesh, not counting the doubling which has already been done (by VertexData::prepareForShadowVolume) to provide the extruded area of the buffer.
lightPos	4D light position in object space, when w=0.0f this represents a directional light.
extrudeDist	The distance to extrude.

◆ getAnimableValueNames()

const StringVector& Ogre::AnimableObject::getAnimableValueNames ( void ) const

inlineinherited

Gets a list of animable value names for this object.

References Ogre::Exception::ERR_ITEM_NOT_FOUND, and OGRE_EXCEPT.

◆ createAnimableValue()

virtual AnimableValuePtr Ogre::AnimableObject::createAnimableValue ( const String & valueName )

inlinevirtualinherited

Create a reference-counted AnimableValuePtr for the named value.

Remarks: You can use the returned object to animate a value on this object, using AnimationTrack. Subclasses must override this if they wish to support animation of their values.

Reimplemented in Ogre::Light.

References Ogre::Exception::ERR_ITEM_NOT_FOUND, and OGRE_EXCEPT.

◆ getTechnique()

virtual Technique* Ogre::Renderable::getTechnique ( void ) const

inlinevirtualinherited

Retrieves a pointer to the Material Technique this renderable object uses.

Remarks: This is to allow Renderables to use a chosen Technique if they wish, otherwise they will use the best Technique available for the Material they are using.

Reimplemented in Ogre::InstanceBatch, Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.

◆ preRender()

virtual bool Ogre::Renderable::preRender	(	SceneManager *	sm,
		RenderSystem *	rsys
	)

inlinevirtualinherited

Called just prior to the Renderable being rendered.

Remarks: OGRE is a queued renderer, so the actual render commands are executed at a later time than the point at which an object is discovered to be visible. This allows ordering & grouping of renders without the discovery process having to be aware of it. It also means OGRE uses declarative render information rather than immediate mode rendering - this is very useful in that certain effects and processes can automatically be applied to a wide range of scenes, but the downside is that special cases are more difficult to handle, because there is not the declared state to cope with it.

: This method allows a Renderable to do something special at the actual point of rendering if it wishes to. When this method is called, all the material render state as declared by this Renderable has already been set, all that is left to do is to bind the buffers and perform the render. The Renderable may modify render state itself if it wants to (and restore it in the postRender call) before the automated render happens, or by returning 'false' from this method can actually suppress the automatic render and perform one of its own.

Returns: true if the automatic render should proceed, false to skip it on the assumption that the Renderable has done it manually.

Reimplemented in Ogre::BillboardChain.

◆ postRender()

virtual void Ogre::Renderable::postRender	(	SceneManager *	sm,
		RenderSystem *	rsys
	)

inlinevirtualinherited

Called immediately after the Renderable has been rendered.

◆ getNumWorldTransforms()

virtual unsigned short Ogre::Renderable::getNumWorldTransforms ( void ) const

inlinevirtualinherited

Returns the number of world transform matrices this renderable requires.

Remarks: When a renderable uses vertex blending, it uses multiple world matrices instead of a single one. Each vertex sent to the pipeline can reference one or more matrices in this list with given weights. If a renderable does not use vertex blending this method returns 1, which is the default for simplicity.

Reimplemented in Ogre::BorderRenderable, Ogre::SubEntity, Ogre::BaseInstanceBatchVTF, Ogre::InstanceBatchHW, and Ogre::InstanceBatchShader.

◆ setUseIdentityProjection()

void Ogre::Renderable::setUseIdentityProjection ( bool useIdentityProjection )

inlineinherited

Sets whether or not to use an 'identity' projection.

Remarks: Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not change this. The default is false.

See also: Renderable::getUseIdentityProjection

◆ getUseIdentityProjection()

bool Ogre::Renderable::getUseIdentityProjection ( void ) const

inlineinherited

Returns whether or not to use an 'identity' projection.

Remarks: Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not change this.

See also: Renderable::setUseIdentityProjection

◆ setUseIdentityView()

void Ogre::Renderable::setUseIdentityView ( bool useIdentityView )

inlineinherited

Sets whether or not to use an 'identity' view.

Remarks: Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not change this. The default is false.

See also: Renderable::getUseIdentityView

◆ getUseIdentityView()

bool Ogre::Renderable::getUseIdentityView ( void ) const

inlineinherited

Returns whether or not to use an 'identity' view.

Remarks: Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not change this.

See also: Renderable::setUseIdentityView

◆ getCastsShadows()

virtual bool Ogre::Renderable::getCastsShadows ( void ) const

inlinevirtualinherited

Method which reports whether this renderable would normally cast a shadow.

Remarks: Subclasses should override this if they could have been used to generate a shadow.

Reimplemented in Ogre::SubEntity, and Ogre::StaticGeometry::GeometryBucket.

◆ setCustomParameter()

void Ogre::Renderable::setCustomParameter	(	size_t	index,
		const Vector4 &	value
	)

inlineinherited

Sets a custom parameter for this Renderable, which may be used to drive calculations for this specific Renderable, like GPU program parameters.

Remarks: Calling this method simply associates a numeric index with a 4-dimensional value for this specific Renderable. This is most useful if the material which this Renderable uses a vertex or fragment program, and has an ACT_CUSTOM parameter entry. This parameter entry can refer to the index you specify as part of this call, thereby mapping a custom parameter for this renderable to a program parameter.

Parameters

index	The index with which to associate the value. Note that this does not have to start at 0, and can include gaps. It also has no direct correlation with a GPU program parameter index - the mapping between the two is performed by the ACT_CUSTOM entry, if that is used.
value	The value to associate.

◆ removeCustomParameter()

void Ogre::Renderable::removeCustomParameter ( size_t index )

inlineinherited

Removes a custom value which is associated with this Renderable at the given index.

Parameters

index Index of the parameter to remove.

See also: setCustomParameter for full details.

◆ hasCustomParameter()

bool Ogre::Renderable::hasCustomParameter ( size_t index ) const

inlineinherited

Checks whether a custom value is associated with this Renderable at the given index.

Parameters

index Index of the parameter to check for existence.

See also: setCustomParameter for full details.

◆ getCustomParameter()

const Vector4& Ogre::Renderable::getCustomParameter ( size_t index ) const

inlineinherited

Gets the custom value associated with this Renderable at the given index.

Parameters

index Index of the parameter to retrieve.

See also: setCustomParameter for full details.

References Ogre::Exception::ERR_ITEM_NOT_FOUND, and OGRE_EXCEPT.

◆ _updateCustomGpuParameter()

virtual void Ogre::Renderable::_updateCustomGpuParameter	(	const GpuProgramParameters::AutoConstantEntry &	constantEntry,
		GpuProgramParameters *	params
	)		const

inlinevirtualinherited

Update a custom GpuProgramParameters constant which is derived from information only this Renderable knows.

Remarks: This method allows a Renderable to map in a custom GPU program parameter based on it's own data. This is represented by a GPU auto parameter of ACT_CUSTOM, and to allow there to be more than one of these per Renderable, the 'data' field on the auto parameter will identify which parameter is being updated. The implementation of this method must identify the parameter being updated, and call a 'setConstant' method on the passed in GpuProgramParameters object, using the details provided in the incoming auto constant setting to identify the index at which to set the parameter.

: You do not need to override this method if you're using the standard sets of data associated with the Renderable as provided by setCustomParameter and getCustomParameter. By default, the implementation will map from the value indexed by the 'constantEntry.data' parameter to a value previously set by setCustomParameter. But custom Renderables are free to override this if they want, in any case.

Parameters

constantEntry	The auto constant entry referring to the parameter being updated
params	The parameters object which this method should call to set the updated parameters.

Reimplemented in Ogre::SubEntity.

References Ogre::GpuProgramParameters::_writeRawConstant(), Ogre::GpuProgramParameters::AutoConstantEntry::data, Ogre::GpuProgramParameters::AutoConstantEntry::elementCount, and Ogre::GpuProgramParameters::AutoConstantEntry::physicalIndex.

◆ setPolygonModeOverrideable()

void Ogre::Renderable::setPolygonModeOverrideable ( bool override )

inlineinherited

Parameters

override true means that a lower camera detail will override this renderables detail level, false means it won't.

◆ getPolygonModeOverrideable()

bool Ogre::Renderable::getPolygonModeOverrideable ( void ) const

inlineinherited

Gets whether this renderable's chosen detail level can be overridden (downgraded) by the camera setting.

inlineinherited

Deprecated:: use UserObjectBindings::setUserAny via getUserObjectBindings() instead.
