| '''OpenGL extension AMD.gcn_shader |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.AMD.gcn_shader to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension exposes miscellaneous features of the AMD "Graphics Core |
| Next" shader architecture that do not cleanly fit into other extensions |
| and are not significant enough alone to warrant their own extensions. |
| This includes cross-SIMD lane ballots, cube map query functions and |
| a functionality to query the elapsed shader core time. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/AMD/gcn_shader.txt |
