Description
S2TC's format specification is very easy to implement, so it is not hard to make a working compressor or decompressor for it. It is based on Color Cell Compression[1] from 1986, and decoding is done entirely using the methods from there. Encoding is done using a search and refinement method that is derived from the methods described in that paper.
This also makes this format a great platform for learning about texture compression and how to tune a compressor for best quality.
S2TC is especially well suited for runtime (on-load) compression of textures, as it is - in low quality settings - way faster than any other texture compressors out there.
Install
As a binary package — by origin, or by package name:
pkg install graphics/s2tc
pkg install s2tcFrom the ports tree:
cd /usr/ports/graphics/s2tc/ && make install cleanTo depend on this port in another port's Makefile:
RUN_DEPENDS= s2tc>0:graphics/s2tc
LIB_DEPENDS= libtxc_dxtn.so:graphics/s2tcPackages
The version each package repository carries. “-” means the repository builds no package of it, “n/a” that there is no such repository.
