OpenGL extension NV.multisample_coverage
This module customises the behaviour of the OpenGL.raw.GLX.NV.multisample_coverage to provide a more Python-friendly API
Overview (from the spec)
The ARB_multisample extension provides a mechanism for antialiasing primitives. This mechanism allows an application to request an additional buffer, the multisample buffer, that is added to the framebuffer. An application can request the number of samples per fragment that are stored in the multisample buffer. Rendering proceeds by writing color, depth, and stencil values for each sample to the multisample buffer. The results are automatically resolved to a single displayable color each time a pixel is updated.
Coverage Sample Anti-Aliasing (CSAA) is an extension to multisample antialiasing. The technique separates "samples" into two types of samples. "Color samples" are samples with color, depth, and stencil information stored in the multisample buffer. "Coverage samples" include both color samples and additional samples that only provide pixel coverage information.
This extension follows the example of the NV_framebuffer_multisample_coverage extension, which adds CSAA support for framebuffer objects. The base description of multisample rendering is written in terms of coverage samples and color samples. The windows system notion of "samples" (SAMPLES_ARB) is layered on top of coverage and color samples.
