Detailed Description

This class is used to access specific elements in an untyped chunk of memory.

Member Function Documentation

virtual physx::PxI32 physx::apex::NxApexCustomBufferIterator::getAttributeIndex ( const char * attributeName ) const [pure virtual]

Returns the index of a certain custom buffer.

virtual void* physx::apex::NxApexCustomBufferIterator::getVertex	(	physx::PxU32	triangleIndex,
		physx::PxU32	vertexIndex
	)		const `[pure virtual]`

Returns the memory start of a specific vertex.

All custom buffers are stored interleaved, so this is also the memory start of the first attribute of this vertex.

virtual void* physx::apex::NxApexCustomBufferIterator::getVertexAttribute	(	physx::PxU32	triangleIndex,
		physx::PxU32	vertexIndex,
		const char *	attributeName,
		NxRenderDataFormat::Enum &	outFormat
	)		const `[pure virtual]`

Returns a pointer to a certain attribute of the specified vertex/triangle.

Parameters:

[in]	triangleIndex	Which triangle
[in]	vertexIndex	Which of the vertices of this triangle (must be either 0, 1 or 2)
[in]	attributeName	The name of the attribute you wish the data for
[out]	outFormat	The format of the attribute, reinterpret_cast the void pointer accordingly.

virtual void* physx::apex::NxApexCustomBufferIterator::getVertexAttribute	(	physx::PxU32	triangleIndex,
		physx::PxU32	vertexIndex,
		physx::PxU32	attributeIndex,
		NxRenderDataFormat::Enum &	outFormat,
		const char *&	outName
	)		const `[pure virtual]`

Returns a pointer to a certain attribute of the specified vertex/triangle.

Note:: This is the faster method than the one above since it won't do any string comparisons

Parameters:

[in]	triangleIndex	Which triangle
[in]	vertexIndex	Which of the vertices of this triangle (must be either 0, 1 or 2)
[in]	attributeIndex	The indexof the attribute you wish the data for (use NxApexCustomBufferIterator::getAttributeIndex to find the index to a certain attribute name
[out]	outFormat	The format of the attribute, reinterpret_cast the void pointer accordingly.
[out]	outName	The name associated with the attribute
