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.

Member Typedef Documentation

◆ CustomParameterMap

typedef map<size_t, Vector4>::type Ogre::Renderable::CustomParameterMap
inherited

◆ MovableObjectArray

@See SceneManager::cullFrustum

Remarks
We don't pass by reference on purpose (avoid implicit aliasing) We perform frustum culling AND test visibility mask at the same time
Parameters
frustumFrustum to clip against
sceneVisibilityFlagsCombined scene's visibility flags (i.e. viewport | scene). Set LAYER_SHADOW_CASTER bit if you want to exclude non-shadow casters.
outCulledObjectsOut. List of objects that are (fully or partially) inside the frustum and should be rendered
lodCameraCamera in which lod levels calculations are based (i.e. during shadow pass renders) Note however, we only use this camera to calulate if should be visible according to mUpperDistance

Constructor & Destructor Documentation

◆ BillboardSet()

Ogre::v1::BillboardSet::BillboardSet ( IdType  id,
ObjectMemoryManager objectMemoryManager,
SceneManager manager,
unsigned int  poolSize = 20,
bool  externalDataSource = false,
uint8  renderQueueId = 110u 
)

Usual constructor - this is called by the SceneManager.

Parameters
nameThe name to give the billboard set (must be unique)
poolSizeThe 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.
externalDataSourceIf 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.

)
virtualinherited

Manually sets the hlms hashes. Don't call this directly.

Reimplemented in Ogre::SubItem.

◆ _setNullDatablock()

virtual void Ogre::v1::BillboardSet::_setNullDatablock ( void  )
virtual

Sets the datablock to a null pointer.

Use case: If you will be destroying an HlmsDatablock and all Renderables associated by it; it makes no sense to change the Renderable's datablock to a default one, only to be destroyed immediately after (you pay an unnecessary performance price).

Remarks
Do not attempt to render a Renderable whose datablock has been set to null. It will crash. You can call setDatablock afterwards though. Use at your own risk, hence the _underscore. See http://ogre3d.org/forums/viewtopic.php?f=25&t=91791&p=534476#p534476

Reimplemented from Ogre::Renderable.

◆ _sortBillboards()

◆ _updateBounds()

virtual void Ogre::v1::BillboardSet::_updateBounds ( void  )
virtual

◆ _updateCustomGpuParameter()

virtual void Ogre::Renderable::_updateCustomGpuParameter ( const GpuProgramParameters_AutoConstantEntry constantEntry,
GpuProgramParameters params 
) const
virtualinherited

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
constantEntryThe auto constant entry referring to the parameter being updated
paramsThe parameters object which this method should call to set the updated parameters.

Reimplemented in Ogre::v1::SubEntity.

◆ 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

◆ 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

◆ getUseIdentityViewProjMatrixIsDynamic()

virtual bool Ogre::Renderable::getUseIdentityViewProjMatrixIsDynamic ( void  ) const
inlinevirtualinherited

Returns whether the Hlms implementation should evaluate getUseIdentityProjection per object at runtime, or if it can assume the Renderable will remain with the same setting until the datablock is flushed (performance optimization)

Remarks
Hlms implementations may ignore this setting (e.g. assume always true or always false) or even not support identity matrix overrides at all. For example currently Unlit supports them all, but will assume this returns always true if getUseIdentityWorldMatrix returns false.

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::v1::BillboardChain.

◆ queryLights()

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

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

Remarks
The lights are filled in
See also
buildLightList
Returns
The list of lights use to lighting this object.

◆ removeBillboard() [1/2]

virtual void Ogre::v1::BillboardSet::removeBillboard ( Billboard pBill)
virtual

Removes a billboard from the set.

Note
This version is more efficient than removing by index.

◆ removeBillboard() [2/2]

virtual void Ogre::v1::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.

◆ removeCustomParameter()

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

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

Parameters
indexIndex of the parameter to remove.
See also
setCustomParameter for full details.

◆ removeQueryFlags()

void Ogre::MovableObject::removeQueryFlags ( uint32  flags)
inlineinherited

As setQueryFlags, except the flags passed as parameters are removed from the existing flags on this object.

◆ removeVisibilityFlags()

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

As setVisibilityFlags, except the flags passed as parameters are removed from the existing flags on this object.

◆ setAutoextend()

virtual void Ogre::v1::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
autoextendtrue to double the pool every time it runs out, false to fail silently.

◆ setAutoUpdate()

void Ogre::v1::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.

◆ setBillboardOrigin()

virtual void Ogre::v1::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
originA member of the BillboardOrigin enum specifying the origin for all the billboards in this set.

Referenced by Ogre::v1::BillboardParticleRenderer::setBillboardOrigin().

◆ setBillboardRotationType()

virtual void Ogre::v1::BillboardSet::setBillboardRotationType ( BillboardRotationType  rotationType)
virtual

Sets billboard rotation type.

Remarks
This setting controls the billboard rotation type, you can deciding rotate the billboard's vertices around their facing direction or rotate the billboard's texture coordinates.
The default settings is BBR_TEXCOORD.
Parameters
rotationTypeA member of the BillboardRotationType enum specifying the rotation type for all the billboards in this set.

◆ setBillboardsInWorldSpace()

virtual void Ogre::v1::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.

◆ setBillboardType()

virtual void Ogre::v1::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
bbtThe type of billboard to render

◆ setBounds()

void Ogre::v1::BillboardSet::setBounds ( const Aabb aabb,
Real  radius 
)

Set the bounds of the BillboardSet.

Remarks
You may need to call this if you're injecting billboards manually, and you're relying on the BillboardSet to determine culling.

◆ 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.

◆ setCommonDirection()

virtual void Ogre::v1::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
vecThe direction for all billboards.
Note
The direction are use as is, never normalised in internal, user are supposed to normalise it himself.

◆ setCommonUpVector()

virtual void Ogre::v1::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
vecThe up-vector for all billboards.
Note
The up-vector are use as is, never normalised in internal, user are supposed to normalise it himself.

◆ setCullIndividually()

virtual void Ogre::v1::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
cullIndividualIf 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.

◆ 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
indexThe 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.
valueThe value to associate.

◆ setDatablock() [1/2]

virtual void Ogre::v1::BillboardSet::setDatablock ( HlmsDatablock datablock)
virtual

Assigns a datablock (i.e. HLMS Material) to this renderable.

Reimplemented from Ogre::Renderable.

◆ setDatablock() [2/2]

void Ogre::Renderable::setDatablock ( IdString  datablockName)
inherited

Assigns a datablock (i.e.

HLMS material) based on its unique name.

Remarks
An null IdString() is valid, it will use the default material

◆ setDatablockOrMaterialName()

void Ogre::Renderable::setDatablockOrMaterialName ( String  materialName,
String  groupName 
)
inherited

First tries to see if an HLMS datablock exist with the given name, if not, tries to search among low level materials.

◆ setDefaultDimensions()

virtual void Ogre::v1::BillboardSet::setDefaultDimensions ( Real  width,
Real  height 
)
virtual

Sets the default dimensions of the billboards in this set.

Remarks
All billboards in a set are created with these default dimensions. The set will render most efficiently if all the billboards in the set are the default size. It is possible to alter the size of individual billboards at the expense of extra calculation. See the Billboard class for more info.
Parameters
widthThe new default width for the billboards in this set.
heightThe new default height for the billboards in this set.

◆ setDefaultHeight()

virtual void Ogre::v1::BillboardSet::setDefaultHeight ( Real  height)
virtual

See setDefaultDimensions - this sets 1 component individually.

static void Ogre::MovableObject::setDefaultLightMask ( uint32  mask)
inlinestaticinherited

Set the default light mask for all future MovableObject instances.

◆ setDefaultQueryFlags()

static void Ogre::MovableObject::setDefaultQueryFlags ( uint32  flags)
inlinestaticinherited

Set the default query flags for all future MovableObject instances.

◆ setDefaultRenderQueueSubGroup()

static void Ogre::Renderable::setDefaultRenderQueueSubGroup ( uint8  subGroup)
inlinestaticinherited

Sets the default render queue sub group for all future Renderable instances.

◆ setDefaultVisibilityFlags()

static void Ogre::MovableObject::setDefaultVisibilityFlags ( uint32  flags)
inlinestaticinherited

Set the default visibility flags for all future MovableObject instances.

◆ setDefaultWidth()

virtual void Ogre::v1::BillboardSet::setDefaultWidth ( Real  width)
virtual

See setDefaultDimensions - this sets 1 component individually.

◆ setLightMask()

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

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

◆ 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.

◆ setLocalAabb()

void Ogre::MovableObject::setLocalAabb ( const Aabb  box)
inherited

Sets the local axis-aligned bounding box for this object.

Remarks
This bounding box is in local coordinates.

◆ setMaterial()

virtual void Ogre::v1::BillboardSet::setMaterial ( const MaterialPtr material)
virtual

Sets the given material. Overrides HLMS materials.

Reimplemented from Ogre::Renderable.

◆ setMaterialName()

void Ogre::Renderable::setMaterialName ( const String name,
const String groupName 
)
inherited

Sets the name of the Material to be used. Prefer using HLMS @See setHlms.

◆ setName()

void Ogre::MovableObject::setName ( const String name)
inlineinherited

Sets a custom name for this node.

Doesn't have to be unique

◆ setPointRenderingEnabled()

virtual void Ogre::v1::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
enabledTrue to enable point rendering, false otherwise

◆ setPolygonModeOverrideable()

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

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

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

◆ setPoolSize()

virtual void Ogre::v1::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
sizeThe new size for the pool.

◆ setPoseWeight()

void Ogre::Renderable::setPoseWeight ( size_t  index,
float  w 
)
inherited

◆ 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.

◆ setRenderingDistance()

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

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

Parameters
distDistance beyond which the object will not be rendered (the default is FLT_MAX, which means objects are always rendered). Values equal or below zero will be ignored, and cause an assertion in debug mode.

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

◆ 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
queueIDEnumerated value of the queue group to use. See the enum RenderQueueGroupID for what kind of values can be used here.
Valid render queue ids are between 0 & 254 inclusive

Reimplemented in Ogre::ParticleSystem, Ogre::Light, Ogre::InternalCubemapProbe, Ogre::v1::Entity, and Ogre::Decal.

◆ setRenderQueueSubGroup()

void Ogre::Renderable::setRenderQueueSubGroup ( uint8  subGroup)
inlineinherited

Sets the render queue sub group.

Remarks
Within the same RenderQueue ID, you may want to have the renderables to have a specific order (i.e. have a mesh, but the hair submesh with alpha blending needs to be rendered last).
RenderQueue Subgroups are useful for manually sorting objects, just like RenderQueue IDs. However, RenderQueue IDs can also be useful for skipping large number of objects through clever compositing and thus a performance optimization. Subgroups cannot be used for such optimizations.
Parameters
subGroupThe sub group. This value can't exceed OGRE_MAKE_MASK( SubRqIdBits ) @See RenderQueue

◆ setShadowRenderingDistance()

void Ogre::MovableObject::setShadowRenderingDistance ( Real  dist)
inlineinherited

Sets the distance at which the object is no longer casting shadows.

Parameters
distDistance beyond which the object will not cast shadows (the default is FLT_MAX, which means objects are always casting shadows). Values equal or below zero will be ignored, and cause an assertion in debug mode.
Note
ShadowRenderingDistance will be clamped to RenderingDistance value
See also
setRenderingDistance

◆ setSortingEnabled()

virtual void Ogre::v1::BillboardSet::setSortingEnabled ( bool  sortenable)
virtual

Enables sorting for this BillboardSet.

(default: off)

Parameters
sortenabletrue to sort the billboards according to their distance to the camera

◆ setStatic()

bool Ogre::MovableObject::setStatic ( bool  bStatic)
inherited

Turns this Node into static or dynamic.

Remarks
Switching between dynamic and static has some overhead and forces to update all static scene when converted to static. So don't do it frequently. Static objects are not updated every frame, only when requested explicitly. Use this feature if you plan to have this object unaltered for a very long times
Note all MovableObjects support switching between static & dynamic after they have been created (eg. InstancedEntity)
Changing this attribute will cause to switch the attribute to our parent node, and as a result, all of its other attached entities. @See Node::setStatic
Returns
True if setStatic made an actual change. False otherwise. Can fail because the object was already static/dynamic, or because switching is not supported

◆ setTextureCoords()

virtual void Ogre::v1::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
coordsis a vector of texture coordinates (in UV space) to choose from for each billboard created in the set.
numCoordsis 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::v1::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()

◆ setUseAccurateFacing()

virtual void Ogre::v1::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
accTrue to use the slower but more accurate model. Default is false.

◆ 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

◆ 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

◆ setUserAny()

virtual OGRE_DEPRECATED void Ogre::Renderable::setUserAny ( const Any anything)
inlinevirtualinherited
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 Renderable. This can be a pointer back to one of your own classes for instance.

◆ 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 that is applied a binary 'and' with the SceneManager's mask and a compositor node pass. To exclude particular objects from rendering. Changes to reserved visibility flags are ignored (won't take effect).

◆ 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.

◆ updateAllBounds()

static void Ogre::MovableObject::updateAllBounds ( const size_t  numNodes,
ObjectData  t 
)
staticinherited

@See SceneManager::updateAllBounds

Remarks
We don't pass by reference on purpose (avoid implicit aliasing)
