Description

This extension adds support for 3D textures compressed using the Adaptive Scalable Texture Compression (ASTC) format.

These formats are compressed in 3D. As such, each slice will contain data for a Width x Height x Depth block of the texture. All transfer operations are done at the granularity of block dimensions.
