Each draw index originally only used one piece of per-object information, so every draw command could just directly use its own index.

WebCurrently I'm supporting Simple, Indexed, Indirect and Indexed Indirect draw commands. The appropriate draw call is selected using a simple switch, using the glDraw--Instanced or glMultiDraw--commands. What I'm planning to do instead though, is use only the multi draw commands, and implement instancing under the hood using parameter duplication.

WebThey can't be because the decision what to draw can be made in a shader by writing to the indirect-draw-buffer. Indirect draws are probably faster on the CPU side but a little slower on GPU side.
