Question:
Is it possible to create 3D models in other applications (e.g. Vue Esprit) and then export these models as .obj files for use in iPad applications?
Solution:1
Have a look at this OBJ loader hosted at google code.
It was developed by Jeff Lamarche in a series of blog posts.
Solution:2
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.
