basis_universal/webgl/transcoder/README.md

basisu_wrappers.cpp contains our JavaScript API (implemented via emscripten bindings), which is a thin layer above our encoder and transcoder's C++ API's. As of Basis Universal v2.0 it supports optional WASM multithreading and WASM64.

Prebuilt versions of basis_transcoder.js and basis_transcoder.wasm are included in the build/ folder, and are sufficient for local demos. To build the transcoder yourself, first install emscripten (tutorial) and cmake (download). Then run:

cd webgl/transcoder/build/
emcmake cmake ../
make
