A graphics processing unit (GPU) comprises a memory, and at least one processor configured to: receive a primitive type buffer comprising a plurality of primitive type entries, wherein each of a plurality of vertices of a vertex buffer of the GPU are associated with one or more of the plurality of primitive type entries, determine primitives based on the plurality of vertices and the associated one or more primitive type entries, and rendering, by the GPU, the primitives based on the plurality of vertices and the associated one or more primitive type entries of the primitive type buffer.
