Using Basis Universal Texture Compression with Metal

In this short article, we’ll take a look at a relatively new compressed texture format called Basis. Basis is developed by Binomial, LLC, a company founded by Rich Geldreich (of crunch fame) and Stephanie Hurlburt.

Basis is unique among compression formats in that it emphasizes efficient transcoding between compressed formats. This means that a single .basis file can be transformed, at runtime, into a format that’s optimal for the target platform, without decompressing it in memory, saving space and bandwidth.

Although Basis is a commercial product, targeted predominantly at game developers, Binomial has contributed their Basis Universal reference encoder and transcoder to the Khronos Group in support of the glTF model format, under the Apache License 2.0.
