| | '''OpenGL extension EXT.draw_buffers2 |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.EXT.draw_buffers2 to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension builds upon the ARB_draw_buffers extension and provides |
| | separate blend enables and color write masks for each color output. In |
| | ARB_draw_buffers (part of OpenGL 2.0), separate values can be written to |
| | each color buffer, but the blend enable and color write mask are global |
| | and apply to all color outputs. |
| | |
| | While this extension does provide separate blend enables, it does not |
| | provide separate blend functions or blend equations per color output. |
| | |
| | |
| | The official definition of this extension is available here: |
| | http://www.opengl.org/registry/specs/EXT/draw_buffers2.txt |
