| | '''OpenGL extension SUN.slice_accum |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.SUN.slice_accum to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | |
| | This extension defines a new accumulation operation which enables the accumulation |
| | buffer to be used for alpha compositing. This enables higher precision alpha |
| | blending than what can be accomplished using the blend operation. |
| | |
| | The official definition of this extension is available here: |
| | http://www.opengl.org/registry/specs/SUN/slice_accum.txt |
