| | '''OpenGL extension ARB.draw_buffers_blend |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.ARB.draw_buffers_blend to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension builds upon the ARB_draw_buffers and |
| | EXT_draw_buffers2 extensions. In ARB_draw_buffers (part of OpenGL |
| | 2.0), separate values could be written to each color buffer. This |
| | was further enhanced by EXT_draw_buffers2 by adding in the ability |
| | to enable blending and to set color write masks independently per |
| | color output. |
| | |
| | This extension provides the ability to set individual blend |
| | equations and blend functions for each color output. |
| | |
| | The official definition of this extension is available here: |
| | http://www.opengl.org/registry/specs/ARB/draw_buffers_blend.txt |
