Describes a source of indices used for drawing.

Variants

IndexBuffer	A buffer uploaded in video memory. Fields buffer The buffer. data_type Type of indices in the buffer. primitives Type of primitives contained in the vertex source.
MultidrawArray	Use a multidraw indirect buffer without indices. Fields buffer The buffer. primitives Type of primitives contained in the vertex source.
MultidrawElement	Use a multidraw indirect buffer with indices. Fields commands The buffer of the commands. indices The buffer of the indices. data_type Type of indices in the buffer. primitives Type of primitives contained in the vertex source.
NoIndices	Don't use indices. Assemble primitives by using the order in which the vertices are in the vertices source. Fields primitives Type of primitives contained in the vertex source.
