| | '''OpenGL extension EXT.blend_func_separate |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.EXT.blend_func_separate to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | Blending capability is extended by defining a function that allows |
| | independent setting of the RGB and alpha blend factors for blend |
| | operations that require source and destination blend factors. It |
| | is not always desired that the blending used for RGB is also applied |
| | to alpha. |
| | |
| | The official definition of this extension is available here: |
| | http://www.opengl.org/registry/specs/EXT/blend_func_separate.txt |
