S3 Texture Compression (S3TC) (sometimes also called DXTn or DXTC) is a group of related image compression algorithms originally developed by S3 Graphics, Ltd. for use in their Savage 3D computer graphics accelerator. Unlike previous image compression algorithms, S3TC's fast random access to individual pixels made it uniquely suited for use in compressing textures in hardware accelerated 3D computer graphics. Its subsequent inclusion in Microsoft's DirectX 6.0 led to widespread adoption of the technology among hardware and software makers. While S3 Graphics is no longer a leading competitor in the graphics accelerator market, license fees are still levied and collected for the use of S3TC technology, for example in consoles.
