OpenGL picking relies on deprecated methods and/or methods known to be particularly slow in general (glReadPixels) or when used with shaders. I already used build-in picking in the past, it's nice until you use lighting and shaders which prevent it from working reliably on some drivers :s

Ardor3D has a build-in support of software picking, you can look at its source code to understand how it works. Basically, this just throws a ray into a triangle if other preliminary tests haven't considered that it has no chance to succeed.

We talked a lot about picking recently, you'll find some information here:
