# basis_universal
Basis Universal GPU Texture and Texture Video Compression Codec
-Basis Universal is a ["supercompressed"](http://gamma.cs.unc.edu/GST/gst.pdf) compressed GPU texture and [compressed texture video](http://gamma.cs.unc.edu/MPTC/) compression system that outputs a highly compressed intermediate file format (.basis) that can be quickly transcoded to a very wide variety of GPU compressed and uncompressed pixel formats: ASTC 4x4 L/LA/RGB/RGBA, PVRTC1 4bpp RGB/RGBA, BC7 mode 6 RGB, BC7 mode 5 RGA/RGBA, BC1-5 RGB/RGBA/X/XY, ETC1 RGB, ETC2 RGBA, ATC RGB/RGBA, and uncompressed raster image 8888/565/4444.

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 multiple images with mipmaps can be stored very efficiently in a single file.
