| '''OpenGL extension NV.framebuffer_multisample_coverage |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.NV.framebuffer_multisample_coverage to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension extends the EXT_framebuffer_multisample |
| specification by providing a new function, |
| RenderBufferStorageMultisampleCoverageNV, that distinguishes |
| between color samples and coverage samples. |
| |
| EXT_framebuffer_multisample introduced the function |
| RenderbufferStorageMultisampleEXT as a method of defining the |
| storage parameters for a multisample render buffer. This function |
| takes a <samples> parameter. Using rules provided by the |
| specification, the <samples> parameter is resolved to an actual |
| number of samples that is supported by the underlying hardware. |
| EXT_framebuffer_multisample does not specify whether <samples> |
| refers to coverage samples or color samples. |
| |
| This extension adds the function |
| RenderbufferStorageMultisamplCoverageNV, which takes a |
| <coverageSamples> parameter as well as a <colorSamples> parameter. |
| These two parameters give developers more fine grained control over |
| the quality of multisampled images. |
| |
