Constructor & Destructor Documentation

BtOgre::DynamicRenderable::DynamicRenderable ( )

Constructor.

BtOgre::DynamicRenderable::~DynamicRenderable ( ) [virtual]

Virtual destructor.

Member Function Documentation

virtual void BtOgre::DynamicRenderable::createVertexDeclaration ( ) [protected, pure virtual]

Creates the vertex declaration.

Remarks:: Override and set mRenderOp.vertexData->vertexDeclaration here. mRenderOp.vertexData will be created for you before this method is called.

virtual void BtOgre::DynamicRenderable::fillHardwareBuffers ( ) [protected, pure virtual]

Fills the hardware vertex and index buffers with data.

Remarks:: This function must call prepareHardwareBuffers() before locking the buffers to ensure the they are large enough for the data to be written. Afterwards the vertex and index buffers (if using indices) can be locked, and data can be written to them.

Real BtOgre::DynamicRenderable::getBoundingRadius ( void ) const [virtual]

Implementation of Ogre::SimpleRenderable.

Real BtOgre::DynamicRenderable::getSquaredViewDepth ( const Ogre::Camera * cam ) const [virtual]

Implementation of Ogre::SimpleRenderable.

void BtOgre::DynamicRenderable::initialize	(	Ogre::RenderOperation::OperationType	operationType,
		bool	useIndices
	)

Initializes the dynamic renderable.

Remarks:: This function should only be called once. It initializes the render operation, and calls the abstract function createVertexDeclaration().

Parameters:

operationType	The type of render operation to perform.
useIndices	Specifies whether to use indices to determine the vertices to use as input.

void BtOgre::DynamicRenderable::prepareHardwareBuffers	(	size_t	vertexCount,
		size_t	indexCount
	)		`[protected]`

Prepares the hardware buffers for the requested vertex and index counts.

Remarks:: This function must be called before locking the buffers in fillHardwareBuffers(). It guarantees that the hardware buffers are large enough to hold at least the requested number of vertices and indices (if using indices). The buffers are possibly reallocated to achieve this.

: The vertex and index count in the render operation are set to the values of vertexCount and indexCount respectively.

Parameters:

vertexCount	The number of vertices the buffer must hold.
indexCount	The number of indices the buffer must hold. This parameter is ignored if not using indices.

Maximum capacity of the currently allocated index buffer.

Maximum capacity of the currently allocated vertex buffer.
