How to Open DAE Files in three.js
three.js is the most popular JavaScript library for 3D on the web, and it ships a loader for almost every common model format.
Short answer · Built in
Yes. three.js opens DAE files as shipped: ColladaLoader from three/addons/loaders/ColladaLoader.js.
Import DAE into three.js, step by step
- 1Check the fileCollada files reference textures by path, so keep the image files next to the .dae.
- 2Import into three.jsColladaLoader from three/addons/loaders/ColladaLoader.js.
- 3Check scale and orientationthree.js works in unitless (most scenes treat 1 unit as 1 metre) and is Y-up. DAE files are declared in the file, so they normally arrive at the right size.
- 4Check materials and animationDAE carries materials and texture references and can carry animation. Look at the model under a neutral light before you build on it.
What comes through
| Shape | Yes, always. |
| Colours and materials | Yes: materials and texture references. |
| Textures | Yes. |
| Animation | Yes, if the file has any. |
Things to watch for
- Collada files are XML, so they are larger and slower to parse than GLB.
- Compress big models with Draco or Meshopt and load them with the matching decoder; it can cut download size several times over.
