The Future of Texture Compression
summary
Basis is a C++ transcoding system that produces a header-only transcoder which converts a single .basis file at runtime into existing GPU block formats (ETC1, DXT/BC, ASTC) and targets hardware-accelerated decoding. The encoder simulates LZ-style backends to optimize size, achieves similar size to JPEG on CPU, and reduces texture data often by half or down to an eighth at low quality; typical encode time is about 20 seconds for a 2K texture on a laptop.
