OpenGL.GL.NV.bindless_multi_draw_indirect

OpenGL extension NV.bindless_multi_draw_indirect

This module customises the behaviour of the OpenGL.raw.GL.NV.bindless_multi_draw_indirect to provide a more Python-friendly API

Overview (from the spec)

This extension combines NV_vertex_buffer_unified_memory and ARB_multi_draw_indirect to allow the processing of multiple drawing commands, whose vertex and index data can be sourced from arbitrary buffer locations, by a single function call.

The NV_vertex_buffer_unified_memory extension provided a mechanism to specify vertex attrib and element array locations using GPU addresses. Prior to this extension, these addresses had to be set through explicit function calls. Now the ability to set the pointer addresses indirectly by extending the GL_ARB_draw_indirect mechanism has been added.

Combined with other "bindless" extensions, such as NV_bindless_texture and NV_shader_buffer_load, it is now possible for the GPU to create draw commands that source all resource inputs, which are common to change frequently between draw calls from the GPU: vertex and index buffers, samplers, images and other shader input data stored in buffers.
