Constructor & Destructor Documentation

◆ SimpleRenderable() [1/2]

Ogre::SimpleRenderable::SimpleRenderable ( )

Constructor.

◆ SimpleRenderable() [2/2]

Ogre::SimpleRenderable::SimpleRenderable ( const String name)

Named constructor.

Member Function Documentation

◆ setMaterial()

virtual void Ogre::SimpleRenderable::setMaterial ( const MaterialPtr mat)
virtual

Reimplemented in Ogre::Volume::Chunk.

◆ getMaterial()

const MaterialPtr& Ogre::SimpleRenderable::getMaterial ( void  ) const
overridevirtual

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

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.

Implements Ogre::Renderable.

◆ setRenderOperation()

virtual void Ogre::SimpleRenderable::setRenderOperation ( const RenderOperation rend)
virtual

◆ getRenderOperation()

void Ogre::SimpleRenderable::getRenderOperation ( RenderOperation op)
overridevirtual

Gets the render operation required to send this object to the frame buffer.

Implements Ogre::Renderable.

◆ setTransform()

void Ogre::SimpleRenderable::setTransform ( const Affine3 xform)

◆ getWorldTransforms()

void Ogre::SimpleRenderable::getWorldTransforms ( Matrix4 xform) const
overridevirtual

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

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.

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

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

Note
If MeshManager::getBonesUseObjectSpace() is true, the first matrix must contain the world transform of the object, and the rest of the matrices must contain the bone transforms in object space.

Implements Ogre::Renderable.

◆ _notifyCurrentCamera()

void Ogre::SimpleRenderable::_notifyCurrentCamera ( Camera cam)
overridevirtual

Internal method to notify the object of the camera to be used for the next rendering operation.

Certain objects may want to do specific processing based on the camera position. This method notifies them in case they wish to do this.

Reimplemented from Ogre::MovableObject.

◆ setBoundingBox()

void Ogre::SimpleRenderable::setBoundingBox ( const AxisAlignedBox box)

◆ getBoundingBox()

const AxisAlignedBox& Ogre::SimpleRenderable::getBoundingBox ( void  ) const
overridevirtual

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

This bounding box is in local coordinates.

Implements Ogre::MovableObject.

◆ _updateRenderQueue()

void Ogre::SimpleRenderable::_updateRenderQueue ( RenderQueue queue)
overridevirtual

Internal method by which the movable object must add Renderable subclass instances to the rendering queue.

The engine will call this method when this object is to be rendered. The object must then create one or more Renderable subclass instances which it places on the passed in Queue for rendering.

Implements Ogre::MovableObject.

◆ visitRenderables()

void Ogre::SimpleRenderable::visitRenderables ( Renderable::Visitor visitor,
bool  debugRenderables = false 
)
overridevirtual

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
visitorPointer 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.
debugRenderablesIf false, only regular renderables will be visited (those for normal display). If true, debug renderables will be included too.

Implements Ogre::MovableObject.

◆ getMovableType()

const String& Ogre::SimpleRenderable::getMovableType ( void  ) const
overridevirtual

Returns the type name of this object.

Implements Ogre::MovableObject.

Reimplemented in Ogre::Volume::Chunk.

◆ getLights()

const LightList& Ogre::SimpleRenderable::getLights ( void  ) const
overridevirtual

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

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

Implements Ogre::Renderable.
