elm-obj-loader

This is an Elm library for importing simple Wavefront .obj files into your WebGL application.

It is currently Elm 0.19, though the previous incarnation works for 0.18.

Examples

* Model viewer * Suzanne from Blender

See the demo source.

Usage

• Export / convert your model from Blender or other 3D content creation tool as an .obj file.
• The default export options from Blender work fine.
• Make sure you keep Write Normals selected.

Limitations

Completely supported face types are those with vertex position, normals and optionally vertex texture coordinates. (v, vn, vt) Only a small subset of the specification is supported though - specifically:

• Your model needs vertex normals (vn).

• Smooth groups are ignored (s n).

• Only tris and quads are supported. (Tris might load slightly faster)

• No free-form curves / surfaces.

• No material library (mtllib) support.

• No negative indexing.
