Chapter 158: ColladaLoader

Core Idea

A loader for the Collada format.

The Collada format is very complex so this loader only supports a subset of what is defined in the official specification.

Assets with a Z-UP coordinate system are transformed it into Y-UP by a simple rotation. The vertex data are not converted.

Code Examples

const loader = new ColladaLoader();
const result = await loader.loadAsync( './models/collada/elf/elf.dae' );
scene.add( result.scene );

• What it demonstrates: Typical usage of ColladaLoader.
