I’ve noticed people have been looking for a obj file importer for processing/java.
Many thanks to Fabien Sanglard for his original code. I’ve added few more things i found to be important to me and added support for JOGL and processing. It runs over part of my framework called Vitamin, so if you are a pure processing user you might want to check the objscene.pde and change the rendering code.  I wanted to keep the obj importer independent of any API/Bind, so it can be easily used by different API/frameworks/whatever. Hopefully it will work that way.

My own math library for processing. It includes 3 and 4 dimensional vectors, 4×4 matrices and quaternions

These are part of my processing graphics renderer. I plan on releasing it sometime this year. Its a limited port of my graphics engine codename Chaos. But that is another story for another time. Enjoy!
