| | '''OpenGL extension AMD.sample_positions |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.AMD.sample_positions to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension provides a mechanism to explicitly set sample positions for a |
| | FBO with multi-sampled attachments. The FBO will use identical sample locations |
| | for all pixels in each attachment. This forces TEXTURE_FIXED_SAMPLE_LOCATIONS |
| | to TRUE if a multi-sampled texture is specified using TexImage2DMultisample |
| | or TexImage3DMultisample. That is, using GetTexLevelParameter to query |
| | TEXTURE_FIXED_SAMPLE_LOCATIONS will always return TRUE if the mechanism is |
| | explicitly used to set the sample positions. |
| | |
| | The official definition of this extension is available here: |
| | http://www.opengl.org/registry/specs/AMD/sample_positions.txt |
