## Detailed Description

Utility class which defines the sub-parts of an Entity.

Remarks:
  Just as meshes are split into submeshes, an Entity is made up of potentially multiple SubMeshes. These are mainly here to provide the link between the Material which the SubEntity uses (which may be the default Material for the SubMesh or may have been changed for this object) and the SubMesh data.

  The SubEntity also allows the application some flexibility in the material properties for this section of a particular instance of this Mesh, e.g. tinting the windows on a car model.

  SubEntity instances are never created manually. They are created at the same time as their parent Entity by the SceneManager method createEntity.

## Member Function Documentation

bool Ogre::SubEntity::_getBuffersMarkedForAnimation | ( | void |  | ) | const

Are buffers already marked as vertex animated?

Definition at line 218 of file OgreSubEntity.h.

Note:
  The positions/normals of the returned vertex data is in object space.

VertexData* Ogre::SubEntity::_getSoftwareVertexAnimVertexData | ( | void |  | ) |

Advanced method to get the temporarily blended software morph vertex information.

Remarks:
  Internal engine will eliminate software animation if possible, this information is unreliable unless added request for software animation via Entity::addSoftwareAnimationRequest.

Mark all vertex data as animated.

void Ogre::SubEntity::_restoreBuffersForUnusedAnimation | ( | bool | hardwareAnimation | ) |

Internal method to copy original vertex data to the morph structures should there be no active animation in use.

virtual void Ogre::Renderable::_updateCustomGpuParameter | ( | const GpuProgramParameters::AutoConstantEntry & | constantEntry,
|  | GpuProgramParameters * | params |
| ) |  |  | const`[virtual, inherited]`

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.

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

virtual bool Ogre::Renderable::getCastsShadows | ( | void |  | ) | const`[virtual, inherited]`

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.

const LightList& Ogre::SubEntity::getLights | ( | void |  | ) | const

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.

virtual const LightList& Ogre::Renderable::getLights | ( | void |  | ) | const`[pure virtual, inherited]`

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.

Implemented in Ogre::BillboardChain, Ogre::BillboardSet, Ogre::Frustum, Ogre::InstancedGeometry::GeometryBucket, and Ogre::SimpleRenderable.

const MaterialPtr& Ogre::SubEntity::getMaterial | ( | void |  | ) | const

Overridden - see Renderable.

virtual const MaterialPtr& Ogre::Renderable::getMaterial | ( | void |  | ) | const`[pure virtual, inherited]`

Retrieves a weak reference to the material this renderable object uses.

Remarks:
  Note that the Renderable also has the option to override the getTechnique method to specify a particular Technique to use instead of the best one available.

Implemented in Ogre::BillboardChain, Ogre::BillboardSet, Ogre::Frustum, Ogre::InstancedGeometry::GeometryBucket, and Ogre::SimpleRenderable.

const String& Ogre::SubEntity::getMaterialName | ( |  | ) | const

Gets the name of the Material in use by this instance.

virtual unsigned short Ogre::Renderable::getNumWorldTransforms | ( | void |  | ) | const`[virtual, inherited]`

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::InstancedGeometry::GeometryBucket.

Definition at line 152 of file OgreRenderable.h.

unsigned short Ogre::SubEntity::getNumWorldTransforms | ( | void |  | ) | const

Overridden - see Renderable.

Entity* Ogre::SubEntity::getParent | ( | void |  | ) | const

Remarks:
  This should only be used by a render system

Definition at line 380 of file OgreRenderable.h.

virtual Real Ogre::Renderable::getSquaredViewDepth | ( | const Camera * | cam | ) | const`[pure virtual, inherited]`

Returns the camera-relative squared depth of this renderable.

Remarks:
  Used to sort transparent objects. Squared depth is used rather than actual depth to avoid having to perform a square root on the result.

Implemented in Ogre::BillboardChain, Ogre::BillboardSet, Ogre::Frustum, Ogre::InstancedGeometry::GeometryBucket, Ogre::Rectangle2D, and Ogre::WireBoundingBox.

Referenced by Ogre::QueuedRenderableCollection::RadixSortFunctorDistance::operator()(), and Ogre::QueuedRenderableCollection::DepthSortDescendingLess::operator()().

Real Ogre::SubEntity::getSquaredViewDepth | ( | const Camera * | cam | ) | const

Overridden, see Renderable.

SubMesh* Ogre::SubEntity::getSubMesh | ( | void |  | ) |

Accessor method to read mesh data.

Technique* Ogre::SubEntity::getTechnique | ( | void |  | ) | const

Overridden - see Renderable.

virtual Technique* Ogre::Renderable::getTechnique | ( | void |  | ) | const`[virtual, inherited]`

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::InstancedGeometry::GeometryBucket.

Definition at line 93 of file OgreRenderable.h.

bool Ogre::Renderable::getUseIdentityProjection | ( | void |  | ) | const`[inherited]`

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

Definition at line 177 of file OgreRenderable.h.

bool Ogre::Renderable::getUseIdentityView | ( | void |  | ) | const`[inherited]`

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

Definition at line 202 of file OgreRenderable.h.

virtual const Any& Ogre::Renderable::getUserAny | ( | void |  | ) | const`[virtual, inherited]`

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

Retrieves the custom user value associated with this object.

Definition at line 330 of file OgreRenderable.h.

const UserObjectBindings& Ogre::Renderable::getUserObjectBindings | ( |  | ) | const`[inherited]`

Return an instance of user objects binding associated with this class.

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

See also:
  UserObjectBindings::setUserAny.

Definition at line 342 of file OgreRenderable.h.

UserObjectBindings& Ogre::Renderable::getUserObjectBindings | ( |  | ) | `[inherited]`

Return an instance of user objects binding associated with this class.

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

See also:
  UserObjectBindings::setUserAny.

Definition at line 336 of file OgreRenderable.h.

VertexData* Ogre::SubEntity::getVertexDataForBinding | ( | void |  | ) |

Retrieve the VertexData which should be used for GPU binding.

virtual void Ogre::Renderable::getWorldTransforms | ( | Matrix4 * | xform | ) | const`[pure virtual, inherited]`

Gets the world transform matrix / matrices for this renderable object.

Remarks:
  If the object has any derived transforms, these are expected to be up to date as long as all the SceneNode structures have been updated before this is called.

  This method will populate xform with 1 matrix if it does not use vertex blending. If it does use vertex blending it will fill the passed in pointer with an array of matrices, the length being the value returned from getNumWorldTransforms.

Note:
  Internal Ogre never supports non-affine matrix for world transform matrix/matrices, the behavior is undefined if returns non-affine matrix here.

See also:
  Matrix4::isAffine.

Implemented in Ogre::BillboardChain, Ogre::BillboardSet, Ogre::Frustum, Ogre::InstancedGeometry::GeometryBucket, Ogre::Rectangle2D, Ogre::SimpleRenderable, and Ogre::WireBoundingBox.

virtual void Ogre::Renderable::postRender | ( | SceneManager * | sm,

Called immediately after the Renderable has been rendered.

Definition at line 127 of file OgreRenderable.h.

void Ogre::SubEntity::prepareTempBlendBuffers | ( | void |  | ) | `[protected]`

Internal method for preparing this Entity for use in animation.

virtual bool Ogre::Renderable::preRender | ( | SceneManager * | sm,
|  | RenderSystem * | rsys |
| ) |  |  | `[virtual, inherited]`

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.

Definition at line 122 of file OgreRenderable.h.

void Ogre::Renderable::setCustomParameter | ( | size_t | index,
|  | const Vector4 & | value |
| ) |  |  | `[inherited]`

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.

Definition at line 240 of file OgreRenderable.h.

void Ogre::SubEntity::setMaterial | ( | const MaterialPtr & | material | ) |

Sets a Material to be used.

Remarks:
  By default a SubEntity uses the default Material that the SubMesh uses. This call can alter that so that the Material is different for this instance.

void Ogre::SubEntity::setMaterialName | ( | const String & | name,
|  | const String & | groupName = `ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME` |
| ) |  |  |

Sets the name of the Material to be used.

Remarks:
  By default a SubEntity uses the default Material that the SubMesh uses. This call can alter that so that the Material is different for this instance.

virtual void Ogre::Renderable::setPolygonModeOverrideable | ( | bool | override | ) | `[virtual, inherited]`

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

Parameters:

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

Definition at line 305 of file OgreRenderable.h.

virtual void Ogre::Renderable::setRenderSystemData | ( | RenderSystemData * | val | ) | const`[virtual, inherited]`

gets render system private data

Remarks:

Definition at line 388 of file OgreRenderable.h.

void Ogre::Renderable::setUseIdentityProjection | ( | bool | useIdentityProjection | ) | `[inherited]`

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.

void Ogre::Renderable::setUseIdentityView | ( | bool | useIdentityView | ) | `[inherited]`

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

Remarks:
