WebThe extension is written against the OpenGL 4.1 Specification, Core Profile, July 25, 2010 Overview The ARB_draw_indirect extension (included in OpenGL 4.0) introduced mechanisms whereby the parameters for a draw function may be provided in a structure contained in a buffer object rather than as parameters to the drawing procedure. 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.
