Member Function Documentation

static size_t* csVertexCompressor::Compress	(	csRef< iRenderBuffer > *	buffers,
		size_t	numBuffers,
		size_t &	newCount
	)			[static]

Compress an array of vertices (i.e.

remove all duplicated vertices).

Parameters:

	buffers	Array of render buffers to compress. All buffers must have the same amount of elements. The pointed-to references will be replaced with the compressed buffers.
	numBuffers	Number of render buffers in buffers.
	newCount	Receives the new vertex count.

Returns:

An array of indices to map from an old index to a new one. The array size will be equal to old the number of vertices. It must be freed with delete[] after use.

static csCompressVertexInfo* csVertexCompressor::Compress	(	csArray< csVector3 > &	vertices,
		csArray< csVector2 > &	texels,
		csArray< csVector3 > &	normals,
		csArray< csColor4 > &	colors
	)			[static]

Compress an array of vertices (i.e.

remove all duplicated vertices). Returns an array of csCompressVertex which can be used to map from the old index to the new one. The 'vertices' table will be modified with the new compressed vertices. If this function returns 0 there is nothing to do (i.e. no duplicate vertices). Otherwise you have to 'delete[]' the returned array.

static csCompressVertexInfo* csVertexCompressor::Compress	(	csVector3 *	vertices,
		csVector2 *	texels,
		csVector3 *	normals,
		csColor4 *	colors,
		size_t	num_vertices,
		csVector3 *&	new_vertices,
		csVector2 *&	new_texels,
		csVector3 *&	new_normals,
		csColor4 *&	new_colors,
		size_t &	new_count
	)			[static]

Compress an array of vertices (i.e.

remove all duplicated vertices). Returns an array of csCompressVertex which can be used to map from the old index to the new one. 'new_count' will be set to the new number of unique vertices (and 'new_vertices' will be the new vertex table with that size). The size of the returned array is 'num_vertices' though since it has to be indexed with the original vertex array. If this function returns 0 there is nothing to do (i.e. no duplicate vertices). Otherwise you have to 'delete[]' the returned array.
