I would like to display 3-D models of building interiors in my iPhone application, but they are in Wavefront OBJ format. Is there an open source implementation of a Wavefront OBJ loader that I could use within my application?

A: 

Both Bill Dudney and Jeff LaMarche have implementations of Wavefront OBJ loaders for the iPhone (unsure if these are related) that you should be able to drop into your project.

Thanks, Brad. I tried Jeff LaMarche's implementation, but my model looked awful; triangles in mesh appearing and disappearing. I guess I need to dust off my Foley and Van Damm text......
