Detailed Description

A GeometryBucket is a the lowest level bucket where geometry with the same vertex & index format is stored.

It also acts as the renderable.

Constructor & Destructor Documentation

◆ GeometryBucket()

Ogre::StaticGeometry::GeometryBucket::GeometryBucket ( MaterialBucket parent,
const VertexData vData,
const IndexData iData 
)

◆ ~GeometryBucket()

virtual Ogre::StaticGeometry::GeometryBucket::~GeometryBucket ( )
virtual

Member Function Documentation

◆ getParent()

MaterialBucket* Ogre::StaticGeometry::GeometryBucket::getParent ( void  )
inline

◆ getVertexData()

const VertexData* Ogre::StaticGeometry::GeometryBucket::getVertexData ( void  ) const
inline

Get the vertex data for this geometry.

◆ getIndexData()

const IndexData* Ogre::StaticGeometry::GeometryBucket::getIndexData ( void  ) const
inline

Get the index data for this geometry.

◆ getMaterial()

const MaterialPtr& Ogre::StaticGeometry::GeometryBucket::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.

◆ getTechnique()

Technique* Ogre::StaticGeometry::GeometryBucket::getTechnique ( void  ) const
overridevirtual

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

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 from Ogre::Renderable.

◆ getRenderOperation()

void Ogre::StaticGeometry::GeometryBucket::getRenderOperation ( RenderOperation op)
overridevirtual

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

Implements Ogre::Renderable.

◆ getWorldTransforms()

void Ogre::StaticGeometry::GeometryBucket::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.

◆ getSquaredViewDepth()

Real Ogre::StaticGeometry::GeometryBucket::getSquaredViewDepth ( const Camera cam) const
overridevirtual

Returns the squared distance between the camera and this renderable.

Used to sort transparent objects. Squared distance is used to avoid having to perform a square root on the result.

Implements Ogre::Renderable.

◆ getLights()

const LightList& Ogre::StaticGeometry::GeometryBucket::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.

◆ getCastsShadows()

bool Ogre::StaticGeometry::GeometryBucket::getCastsShadows ( void  ) const
overridevirtual

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

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

Reimplemented from Ogre::Renderable.

◆ assign()

bool Ogre::StaticGeometry::GeometryBucket::assign ( QueuedGeometry qsm)

Try to assign geometry to this bucket.

Returns
false if there is no room left in this bucket

◆ build()

void Ogre::StaticGeometry::GeometryBucket::build ( bool  stencilShadows)

Build.

◆ dump()

void Ogre::StaticGeometry::GeometryBucket::dump ( std::ofstream &  of) const

Dump contents for diagnostics.
