01d391cc2a PVRTC1 apparently always use wrap addressing when fetching the adjacent block colors (even when clamp texture addressing is being used), so we don't need the wrap vs. clamp option anymore. It's always wrap and that's that. 2019-09-29 19:34:00 -07:00

54304fa014 - Adding PVRTC2 RGB/RGBA and ETC2 EAC R11 and RG11
- Renaming -no_auto_global_sel_pal to -auto_global_sel_pal, disabling global selector palette usage by default to speed up compression on small images
- Renaming texture format enums
- Fixing uninitialized memory issue in front end - it wouldn't have affected the correctness of the output, or output quality
- Bumping command line tool up to v1.10

33996b1a5f Important: Changing the Basis file version, so any existing files will need to be recompressed!
Adding new fields to the basis header: texture type and framerate. Texture type may be 2D, 2D array, video, volume, or cubemap array. The compressor makes sure that anything other than pure 2D follows certain constraints (cubemap arrays must have a multiple of 6 input images, videos/texture array images all must have the same resolution/# of mipmaps, etc.)
When unpacking cubemaps, the -unpack command now writes cubemap .KTX files which various tools like PVRTexTool support.

16c9e35c45 Removing detex dependency
Adding new GPU texture format decoders for BC1/4/5, ETC2 EAC alpha, and BC7 mode 6
Adding GPU texture unpack failure checks and warnings
Adding support for 3 color blocks to transcoder, and making sure that BC3 blocks will never use 3 color (punchthrough alpha) blocks.
