3D models in Three.js

Some of our APIs support 3D models using Three.js.

Pre-built 3D models (with pre-built covering materials) may be uploaded and inserted into Worlds.

The APIs that use Three.js may include some or all of the following libraries for loading 3D models:

• OBJLoader
• MTLLoader
• TGALoader
• GLTFLoader

If there is a library missing you can include it yourself.

Here are sample Three.js Worlds containing 3D models plus materials:

Warning: MTL files and Three.js versions

Some MTL files work with old Three.js versions (old APIs on this site) but not with new Three.js versions (new APIs).

One known issue is the line "Tr 1" in MTL files. The solution is to either use an old API, or edit the MTL file to change "Tr 1" to "Tr 0" or remove the line. See discussion.
