A WebGL demo rendering a glTF 3D model with .basis
texture files, transcoded into one of the following compressed texture formats:
Requires WebAssembly and WebGL support.
The glTF model in this demo uses a hypothetical GOOGLE_texture_basis
extension. That extension is defined for the sake of example only – the glTF format will officially embed Basis files within a KTX2 wrapper, through a new extension that is currently in development.
See how to run things locally, or (with Node.js installed), run:
npx serve
The console will display a localhost
URL for local testing, and (on supported WiFi networks and devices) may also display an IP address accessible by other devices on the same network. Note that mobile devices must support WebAssembly to run this demo. Learn more about remote debugging your android devices.
Prebuilt versions of basis_transcoder.js
and basis_transcoder.wasm
are included in the wasm/build/
folder, and are sufficient for local demos. To build the transcoder yourself, first install emscripten (tutorial) and cmake (download). Then run:
cd webgl/gltf-demo/wasm/build/ emcmake cmake ../ make
