OpenGL.GL.KHR.texture_compression_astc_hdr

OpenGL extension KHR.texture_compression_astc_hdr

This module customises the behaviour of the OpenGL.raw.GL.KHR.texture_compression_astc_hdr to provide a more Python-friendly API

Overview (from the spec)

Adaptive Scalable Texture Compression (ASTC) is a new texture compression technology that offers unprecendented flexibility, while producing better or comparable results than existing texture compressions at all bit rates. It includes support for 2D and slice-based 3D textures, with low and high dynamic range, at bitrates from below 1 bit/pixel up to 8 bits/pixel in fine steps.

The goal of this extension is to support the full 2D profile of the ASTC texture compression specification, and allow construction of 3D textures from multiple 2D slices.

ASTC-compressed textures are handled in OpenGL ES and OpenGL by adding new supported formats to the existing mechanisms for handling compressed textures.

The official definition of this extension is available here: http://www.opengl.org/registry/specs/KHR/texture_compression_astc_hdr.txt
