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.

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

virtual

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.

Implements Ogre::Renderable.

getTechnique()

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

virtual

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 from Ogre::Renderable.

getRenderOperation()

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

virtual

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

virtual

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 transform 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.

Implements Ogre::Renderable.

getSquaredViewDepth()

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

virtual

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.

Implements Ogre::Renderable.

getLights()

const LightList& Ogre::StaticGeometry::GeometryBucket::getLights ( void  ) const

virtual

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.

Implements Ogre::Renderable.

getCastsShadows()

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

virtual

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.

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.
