Detailed Description
A simple reference implemenation rendering Wavefront OBJ format 3D models.
See http://en.wikipedia.org/wiki/Obj
The Open Asset Library implementation also supports OBJ, but there are a few issues there:
- some bugs in how tags are parsed
- only works for native filesystem-based OBJ files
OBJ is simple enough so this is a quick reference implementation.
A note to users of this model: in the interest of rendering performance, vertex data is copied per vertex. That is, it is not indexed per vertex, but instead the vertex data (including normals etc) is copied.
So if you have a large model with a lot of shared vertices, this approach could be too memory intensive.
