With the default DYNAMIC_EXECUTION=1, embind generates its invokers at
runtime with new Function(). A Content-Security-Policy without
'unsafe-eval' blocks this, so the transcoder and encoder fail to start
with an EvalError.
Add two CMake options to webgl/transcoder and webgl/encoder:
- NO_DYNAMIC_EXECUTION (default OFF) adds -s DYNAMIC_EXECUTION=0.
- EMBIND_AOT (default ON, only used with NO_DYNAMIC_EXECUTION) adds
-s EMBIND_AOT=1. This generates the invokers at build time, so
embind calls stay as fast as with the default build.
The default build does not change. The .wasm output is byte-identical
in all configurations; only the JS glue changes.
Fixes#464
The cPackUASTC* values are members of an anonymous enum. embind's
constant() registers a constant against the type of its value, and no
binding exists for an anonymous enum type. embind therefore waits for
that type forever, and the constants never appear on the module.
Module.cPackUASTCLevelDefault and the others are undefined in the
shipped basis_encoder.js.
Cast the values to uint32_t so that they bind as plain numbers.
EMBIND_AOT=1 makes this a link error ("Missing binding for type"), so
this change is also necessary to build the encoder with that flag.
This update impacts the UASTC HDR 4x4, UASTC HDR 6x6i, and XUASTC LDR formats. New KTX2 files in these specific formats using v2.1 can't be loaded using v2.0, however we've kept backwards compatibility with all of our previously written KTX2 files. (v2.1 can transcode all previously written files.)
This is part of our effort to be compatible with Khronos's specification.
bc6hf encoder's smooth block path updated to handle inputs with texels close to MAX_HALF_FLOAT.
Adding command line options to basisu tool so it can write either v2.0 or v1.6 compatible UASTC HDR 6x6i files. The default is v1.6.
Updating WebGL KTX2 testbed so on ASTC devices it automatically switches between sRGB or linear internal formats for the created texture.
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)
- 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
By default, emscripten's generated javascript modules lives in the global object "Module'.
This makes it impossible to load multiple emscripten modules on the same page.
In attempt to avoid namespace collision, this change modularizes the emscripten build so the Module is instead called 'BASIS'.
Many target applications for Basis are likely to already be using other emscripten modules.
Testing:
The existing webgl/(texture|gltf) pages have been updated to use the new name and seem to operate as before
