Can I import .obj files for use on the iPad

Is it possible to create 3D models in other applications (e.g. Vue Esprit) and then export th开发者_JAVA百科ese models as .obj files for use in iPad applications?

There isn't any built in support for this, but you can use any C or C++ based OBJ loader to get the data into a usable format, and then render using your standard GL functions.

A good place to start is the GLGravity sample, which has a 3D teapot that it draws, this doesn't have an OBJ loader though.

Have a look at this OBJ loader hosted at google code.

It was developed by Jeff Lamarche in a series of blog posts.
