| | '''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. |
| | |
