Mesh Import from Wavefront OBJ Format

Description

.OBJ is a simple file format for description of geometry. SceneJS needs to import geometry, material and texture from these into a scene graph.

Proposed Solution

Create a SceneJS.LoadOBJ node that generates its subgraph when first visited by loading and parsing an OBJ file, in a similar manner to the existing SceneJS.loadCollada node:

var graph = new SceneJS.LoadOBJ({
      uri: "http://foo.com/files/myobj.obj"
})

Limitations

V0.7.5 would provide limited OBJ support, where there would be documented guidelines for what drawing programs may export to OBJ files that are desired to work with SceneJS. Initially supported features are:

• Triangle import only
• Groups
• Textures
