PR 408's cmakelists.txt file has too many issues (OpenCL breaks on Windows/OSX) and changing our options to have the "BASISU_" prefix will break upstream builds.
Fixing overflow issue on extreme colors in color_distance().
Explicitly disabling unaligned addressing in miniz and transcoder when UBSAN is enabled
Disabling a needless optimization in transcoder causing ubsan issues (that could have easily been worked around in a different way, but it was an unnecessary optimization to begin with)
Rebuild wasm builds
- Optimized ETC1S encoder (3-4.5x faster)
- Added optional SSE 4.1 support to encoder
- Switched from std::vector to a custom vector in the encoder and transcoder
- Added CppSPMD (SSE only for now)
- UASTC RDO is now more effective, but the command line parameter controlling qualiy has changed (to "lambda")
Encoder is now a library in the "encoder" directory
JavaScript wrappers now expose the entire codec: encoder, transcoder, container independent transcoding, and .basis file information
- Removing BC7 mode 6 support from transcoder (will alway use the much smaller mode 5 tables now)
- Adding BMP support
- Adding -bench mode, for development
- CMakeLists.txt file now compatible with Visual Studio 2019 (MSVC)
- For PVRTC1, we now memset() any extra blocks after the blocks we know will be transcoded into. This is done because in GL there is padding that occurs on textures smaller than 8x8.
- Removing all OpenMP usage and replacing it with a basis C++11 job system.
- Fixing TSVQ class so it can split very long "thin" clusters that before weren't being split. This improves endpoint quantization on videos and complex 2D textures.
- More frontend perf. optimizations.
Tested on OSX, Linux with gcc/clang, and Win using MSVC 2019.
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.
