OpenGL extension INTEL.map_texture
This module customises the behaviour of the OpenGL.raw.GL.INTEL.map_texture to provide a more Python-friendly API
Overview (from the spec) Systems with integrated GPUs can share the same physical memory between CPU and GPU. This feature, if exposed by API, can bring significant performance benefits for graphics applications by reducing the complexity of uploading/accessing texture contents. This extension enables CPU direct access to the GPU memory holding textures.
The problem with texture memory directly exposed to clients is that textures are often 'tiled'. Texels are kept in specific layout to improve locality of reference and thus performance of texturing. This 'tiling' is specific to particular hardware and would be thus difficult to use.
This extension allows to create textures with 'linear' layout which allows for simplified access on user side (potentially sacrificing some performance during texture sampling).
The official definition of this extension is available here:
