Detailed Description

Class providing a much simplified interface to generating manual objects with custom geometry.

Remarks: Building one-off geometry objects manually usually requires getting down and dirty with the vertex buffer and vertex declaration API, which some people find a steep learning curve. This class gives you a simpler interface specifically for the purpose of building a 3D object simply and quickly. Note that if you intend to instance your object you will still need to become familiar with the Mesh class.

: This class draws heavily on the interface for OpenGL immediate-mode (glBegin, glVertex, glNormal etc), since this is generally well-liked by people. There are a couple of differences in the results though - internally this class still builds hardware buffers which can be re-used, so you can render the resulting object multiple times without re-issuing all the same commands again. Secondly, the rendering is not immediate, it is still queued just like all OGRE objects. This makes this object more efficient than the equivalent GL immediate-mode commands, so it's feasible to use it for large objects if you really want to.

To construct some geometry with this object:

If you know roughly how many vertices (and indices, if you use them) you're going to submit, call estimateVertexCount and estimateIndexCount. This is not essential but will make the process more efficient by saving memory reallocations.
Call begin() to begin entering data
For each vertex, call position(), normal(), textureCoord(), colour() to define your vertex data. Note that each time you call position() you start a new vertex. Note that the first vertex defines the components of the vertex - you can't add more after that. For example if you didn't call normal() in the first vertex, you cannot call it in any others. You ought to call the same combination of methods per vertex.
If you want to define triangles (or lines/points) by indexing into the vertex list, you can call index() as many times as you need to define them. If you don't do this, the class will assume you want triangles drawn directly as defined by the vertex list, i.e. non-indexed geometry. Note that stencil shadows are only supported on indexed geometry, and that indexed geometry is a little faster; so you should try to use it.
Call end() to finish entering data.
Optionally repeat the begin-end cycle if you want more geometry using different rendering operation types, or different materials After calling end(), the class will organise the data for that section internally and make it ready to render with. Like any other MovableObject you should attach the object to a SceneNode to make it visible. Other aspects like the relative render order can be controlled using standard MovableObject methods like setRenderQueueGroup.

: You can also use beginUpdate() to alter the geometry later on if you wish. If you do this, you should call setDynamic(true) before your first call to begin(), and also consider using estimateVertexCount / estimateIndexCount if your geometry is going to be growing, to avoid buffer recreation during growth.

: Note that like all OGRE geometry, triangles should be specified in anti-clockwise winding order (whether you're doing it with just vertices, or using indexes too). That is to say that the front of the face is the one where the vertices are listed in anti-clockwise order.

Member Typedef Documentation

◆ MovableObjectArray

typedef FastArray<MovableObject*> Ogre::MovableObject::MovableObjectArray

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

frustum	Frustum to clip against
sceneVisibilityFlags	Combined scene's visibility flags (i.e. viewport \| scene). Set LAYER_SHADOW_CASTER bit if you want to exclude non-shadow casters.
outCulledObjects	Out. List of objects that are (fully or partially) inside the frustum and should be rendered

Member Function Documentation

◆ _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.

void Ogre::v1::ManualObject::_releaseManualHardwareResources ( )

inlineoverridevirtual

Reimplemented from Ogre::MovableObject.

◆ _restoreManualHardwareResources()

virtual void Ogre::MovableObject::_restoreManualHardwareResources ( )

inlinevirtualinherited

Notifies the movable object that hardware resources should be restored.

Remarks: Called automatically by RenderSystem if hardware resources were lost and can not be restored using some internal mechanism. Among affected resources are nested shadow renderables, ManualObjects, etc.

Reimplemented in Ogre::v1::Rectangle2D.

◆ _updateRenderQueue()

void Ogre::v1::ManualObject::_updateRenderQueue	(	RenderQueue *	queue,
		Camera *	camera,
		const Camera *	lodCamera
	)

overridevirtual

Reimplemented from Ogre::MovableObject.

◆ 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.

◆ 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.

◆ begin()

virtual void Ogre::v1::ManualObject::begin	(	const String &	materialName,
		OperationType	opType = `OT_TRIANGLE_LIST`,
		const String &	groupName = `ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME`
	)

virtual

Start defining a part of the object.

Remarks: Each time you call this method, you start a new section of the object with its own material and potentially its own type of rendering operation (triangles, points or lines for example).

Parameters

materialName	The name of the material to render this part of the object with.
opType	The type of operation to use to render.

◆ beginUpdate()

virtual void Ogre::v1::ManualObject::beginUpdate ( size_t sectionIndex )

virtual

Start the definition of an update to a part of the object.

Remarks: Using this method, you can update an existing section of the object efficiently. You do not have the option of changing the operation type obviously, since it must match the one that was used before.

Note: If your sections are changing size, particularly growing, use estimateVertexCount and estimateIndexCount to pre-size the buffers a little larger than the initial needs to avoid buffer reconstruction.

Parameters

sectionIndex The index of the section you want to update. The first call to begin() would have created section 0, the second section 1, etc.

◆ buildLightList()

static void Ogre::MovableObject::buildLightList	(	const size_t	numNodes,
		ObjectData	t,
		const LightListInfo &	globalLightList
	)

		AxisAlignedBox *	outBox
	)

staticinherited

◆ clear()

virtual void Ogre::v1::ManualObject::clear ( )

virtual

Completely clear the contents of the object.

Remarks: Clearing the contents of this object and rebuilding from scratch is not the optimal way to manage dynamic vertex data, since the buffers are recreated. If you want to keep the same structure but update the content within that structure, use beginUpdate() instead of clear() begin(). However if you do want to modify the structure from time to time you can do so by clearing and re-specifying the data.

◆ colour() [1/2]

virtual void Ogre::v1::ManualObject::colour ( const ColourValue & col )

virtual

Add a vertex colour to a vertex.

◆ colour() [2/2]

virtual void Ogre::v1::ManualObject::colour	(	Real	r,
		Real	g,
		Real	b,
		Real	a = `1.0f`
	)

Add a vertex colour to a vertex.

Parameters

r,g,b,a Colour components expressed as floating point numbers from 0-1

		const String &	groupName = `ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME`,
		bool	buildShadowMapBuffers = `true`
	)

virtual

Convert this object to a Mesh.

Remarks: After you've finished building this object, you may convert it to a Mesh if you want in order to be able to create many instances of it in the world (via Entity). This is optional, since this instance can be directly attached to a SceneNode itself, but of course only one instance of it can exist that way.

Note: Only objects which use indexed geometry may be converted to a mesh.

Parameters

meshName	The name to give the mesh
groupName	The resource group to create the mesh in
buildShadowMapBuffers	True to create an optimized copy of the vertex buffers for efficient shadow mapping.

◆ 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.

◆ cullFrustum()

static void Ogre::MovableObject::cullFrustum	(	const size_t	numNodes,

@See SceneManager::cullLights &

See also: MovableObject::cullFrustum Produces the global list of visible lights that is needed in buildLightList

Remarks: We don't pass ObjectData by reference on purpose (avoid implicit aliasing) It's declared here because all affected elements are from MovableObject IMPORTANT: It is assumed that all objects in ObjectData are Lights.

Parameters

outGlobalLightList	Output, a list of lights, contiguously placed
frustums	An array of all frustums we need to check against
cubemapFrustums	An array of all frustums that are used at least once as cubemaps (@See SceneManager::createCamera)

void Ogre::MovableObject::detachFromParent ( )

inherited

Detaches an object from a parent SceneNode if attached.

◆ end()

virtual ManualObjectSection* Ogre::v1::ManualObject::end ( )

virtual

Finish defining the object and compile the final renderable version.

virtual

Estimate the number of vertices ahead of time.

Remarks: Calling this helps to avoid memory reallocation when you define vertices. Also very handy when using beginUpdate() to manage dynamic data - you can make the vertex buffers a little larger than their initial needs to allow for growth later with this method.

◆ position() [1/2]

virtual void Ogre::v1::ManualObject::position ( const Vector3 & pos )

virtual

Add a vertex position, starting a new vertex at the same time.

Remarks: A vertex position is slightly special among the other vertex data methods like normal() and textureCoord(), since calling it indicates the start of a new vertex. All other vertex data methods you call after this are assumed to be adding more information (like normals or texture coordinates) to the last vertex started with position().

◆ position() [2/2]

virtual void Ogre::v1::ManualObject::position	(	Real	x,
		Real	y,
		Real	z
	)

virtual

Add a vertex position, starting a new vertex at the same time.

Remarks: A vertex position is slightly special among the other vertex data methods like normal() and textureCoord(), since calling it indicates the start of a new vertex. All other vertex data methods you call after this are assumed to be adding more information (like normals or texture coordinates) to the last vertex started with position().

◆ quad()

virtual void Ogre::v1::ManualObject::quad	(	uint32	i1,
		uint32	i2,
		uint32	i3,
		uint32	i4
	)

virtual

Add a set of 4 vertex indices to construct a quad (out of 2 triangles); this is a shortcut to calling index() 6 times, or triangle() twice.

It's only valid for triangle list operations.

Note: 32-bit indexes are not supported on all cards and will only be used when required, if an index is > 65535.

Parameters

i1,i2,i3,i4 4 vertex indices from 0 to 4294967295 defining a quad.

◆ queryLights()

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

◆ removeQueryFlags()

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.

◆ 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.

◆ setDefaultLightMask()

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

◆ setDefaultVisibilityFlags()

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

inlinestaticinherited

Set the default visibility flags for all future MovableObject instances.

◆ setDynamic()

virtual void Ogre::v1::ManualObject::setDynamic ( bool dyn )

inlinevirtual

Use before defining geometry to indicate that you intend to update the geometry regularly and want the internal structure to reflect that.

◆ setKeepDeclarationOrder()

void Ogre::v1::ManualObject::setKeepDeclarationOrder ( bool keepOrder )

inline

Sets whether or not to keep the original declaration order when queuing the renderables.

Remarks: This overrides the default behavior of the rendering queue, specifically stating the desired order of rendering. Might result in a performance loss, but lets the user to have more direct control when creating geometry through this class.

Parameters

keepOrder Whether to keep the declaration order or not.

◆ 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.

◆ setMaterialName()

		const String &	name,
		const String &	group = `ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME`
	)

virtual

Alter the material for a subsection of this object after it has been specified.

Remarks: You specify the material to use on a section of this object during the call to begin(), however if you want to change the material afterwards you can do so by calling this method.

Parameters

subIndex	The index of the subsection to alter
name	The name of the new material to use

◆ setName()

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

inlineinherited

Sets a custom name for this node.

Doesn't have to be unique

◆ 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.

◆ setReadable()

virtual void Ogre::v1::ManualObject::setReadable ( bool readable )

inlinevirtual

Use before defining geometry to indicate that you intend to be able to read back from the geometry buffers again down the line (object convertion to v2, physics engine body creation...

◆ setRenderingDistance()

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

inlineinherited

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

Parameters

dist	Distance 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

pixelSize Number 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

queueID Enumerated 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.

◆ setShadowRenderingDistance()

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

inlineinherited

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

Parameters

dist	Distance 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

◆ 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

◆ setUseIdentityProjection()

void Ogre::v1::ManualObject::setUseIdentityProjection ( bool useIdentityProjection )

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

Remarks: Usually ManualObjects 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. Normally you don't need to change this. The default is false.

See also: ManualObject::getUseIdentityProjection

◆ setUseIdentityView()

void Ogre::v1::ManualObject::setUseIdentityView ( bool useIdentityView )

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

Remarks: Usually ManualObjects 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. Normally you don't need to change this. The default is false.

See also: ManualObject::getUseIdentityView

◆ 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.

◆ setWriteOnly()

virtual void Ogre::v1::ManualObject::setWriteOnly ( bool writeOnly )

inlinevirtual

Same as setReadable, but with the invese scemantic.

◆ tangent() [1/2]

virtual void Ogre::v1::ManualObject::tangent ( const Vector3 & tan )

virtual

Add a vertex tangent to the current vertex.

Remarks: Vertex tangents are most often used for dynamic lighting, and their components should be normalised. Also, using tangent() you enable VES_TANGENT vertex semantic, which is not supported on old non-SM2 cards.

◆ tangent() [2/2]

virtual void Ogre::v1::ManualObject::tangent	(	Real	x,
		Real	y,
		Real	z
	)

virtual

Add a vertex tangent to the current vertex.

Remarks: Vertex tangents are most often used for dynamic lighting, and their components should be normalised. Also, using tangent() you enable VES_TANGENT vertex semantic, which is not supported on old non-SM2 cards.
