Function Documentation

rs_allocation rsgMeshGetIndexAllocation	(	rs_mesh	m,
		uint32_t	index
	)

Returns an allocation containing index data or a null allocation if only the primitive is specified

Parameters:

m	mesh to get data from
index	index of the index allocation

Returns:

allocation containing index data

rs_primitive rsgMeshGetPrimitive	(	rs_mesh	m,
		uint32_t	index
	)

Returns the primitive describing how a part of the mesh is rendered

Parameters:

m	mesh to get data from
index	index of the primitive

Returns:

primitive describing how the mesh is rendered

uint32_t rsgMeshGetPrimitiveCount

(

rs_mesh

m

)

Meshes could have multiple index sets, this function returns the number.

Parameters:

m	mesh to get data from

Returns:

number of primitive groups in the mesh. This would include simple primitives as well as allocations containing index data

rs_allocation rsgMeshGetVertexAllocation	(	rs_mesh	m,
		uint32_t	index
	)

Returns an allocation that is part of the mesh and contains vertex data, e.g. positions, normals, texcoords

Parameters:

m	mesh to get data from
index	index of the vertex allocation

Returns:

allocation containing vertex data

uint32_t rsgMeshGetVertexAllocationCount

(

rs_mesh

m

)

Returns the number of allocations in the mesh that contain vertex data

Parameters:

m	mesh to get data from

Returns:

number of allocations in the mesh that contain vertex data
