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