Re: [JAVA3D] light at given point

One issue you have is that "illumination" is several different things (diffuse, specular, ambient). How would you want to combine them? I imagine you could scan your scene for all lights, test if the point is within the bounds of each light and compute the "illumination". - John Wright Starfire

Justin, Just one more observation/question. I have looked at both the JOGL and Xith3D sites and it appears that implementing 3D applications via Xith3D might be less complex than using a JOGL impl. I am developing basic interactive graphics that would run on a Windows based workstation with a 2MH

Hi, I don't mean to interrupt your Java 3D/Xith/JOGL discussion, but I'm having a curious problem with my behaviors. I'm using one behavior to move the view through space (an extension based on KeyNavigatorBehavior), but about every other time (or so) I run it, it freezes - no behaviors are called
