@@ -3,7 +3,7 @@ Basis Universal GPU Texture Compression Codec
Basis Universal is a GPU texture compression system that outputs a highly compressed intermediate file format (.basis) that can be quickly transcoded to a wide variety of GPU texture compression formats: PVRTC1 4bpp RGB, BC7 mode 6 RGB, BC1-5, ETC1, and ETC2. We will be adding ASTC RGB or RGBA, BC7 mode 4/5 RGBA, and PVRTC1 4bpp RGBA next. Basis files support non-uniform texture arrays, so cubemaps, volume textures, texture arrays, mipmap levels, video sequences, or arbitrary texture "tiles" can be stored in a single file. The compressor is able to exploit color and pattern correlations across the entire file.
So far, we've compiled the code using MSVS 2019, under Ubuntu x64 using cmake with either clang 3.8 or gcc 5.4, and emscripten 1.35 to asm.js. The compressor uses OpenMP for multithreading, but if you don't have OpenMP it'll still work (just much more slowly). The transcoder is currently single threaded (and doesn't use OpenMP).

(Be sure to use this version, as earlier versions fail with internal errors/exceptions during compilation.)
