From this [1] it sounds like the texture is a modified variant of ETC1, which gets loaded up from disk into memory as such, and transcoded on the CPU into target GPU format (DXT, PVRTC, etc), and then uploaded to VRAM. If so that sounds similar to their previous Crunch library [2], in that it does transcoding on the CPU before moving the texture to the GPU - but most likely much faster than Crunch because it starts with ETC as shared basis. (And artifacts are a common with transcoding between compressed formats, especially when transparency is present, but I have high hopes for this one considering the authors! :) ) Authors suggest that a version that transcodes on the GPU would be possible - that would be really interesting, I would imagine that would be even faster, although at the cost of higher texture memory usage.

That paper described the inspiration for Basis, but Basis itself is slightly different. https://github.com/binomialLLC/basis_universal#quick-basis-f... > Internally, Basis files are composed of a non-uniform texture array of one or more 2D ETC1S texture "slices". ETC1S is a simple subset of the ETC1 texture format popular on Android.
