| Prebuilt versions of `basis_transcoder.js` and `basis_transcoder.wasm` are included in the `transcoder/build/` folder, and are sufficient for local demos. To build the transcoder yourself, first install emscripten ([tutorial](https://webassembly.org/getting-started/developers-guide/)) and cmake ([download](https://cmake.org/download/)). Then run: | |
| ```shell | |
| cd webgl/transcoder/build/ | |
| emcmake cmake ../ | |
| make | |
| ``` |
