Everything about PVRTC
Lossy texture compression format family
PVRTC and PVRTC2 are a family of lossy, fixed-rate texture compression formats used in PowerVR's MBX, SGX and Rogue technologies. The PVRTC algorithm is documented in Simon Fenney's paper "Texture Compression using Low-Frequency Signal Modulation" that was presented at Graphics Hardware 2003. Wikipedia →
