Requires WebAssembly and WebGL support.
Renders a single texture, using the transcoder (compiled to WASM with emscripten) to generate one of the following compressed texture formats:
On browsers that don‘t support BC1 (Firefox is one), there’s a low-quality fallback code path for opaque textures (but no fallback for BC3 yet). Note that the fallback path only converts to 16-bit RGB images at the moment, so the quality isn't as good as it should be.
Renders a glTF 3D model with
.basis texture files, transcoded into one of the following compressed texture formats:
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.
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.
