I want to point out that picking is *heavily* related to graphics drivers/cards. Java code may be used to process results of picking, but picking itself is a hardware operation that occurs during rendering to framebuffers.
No it's not. In both Java3D and Aviatrix3D we do picking purely in software. It does it's own ray intersection calculations through walking the scene graph checking against bounds and optionally geometry. If you want multi-threaded code to actually work, using hardware picking is going to cause severe problems as what appears on the screen may well be 2 or 3 frames behind the application code.
