[JAVA3D] Viewing and Objects......help!!

[Sackmunky]

I am moving the viewer around a scene. I want to place a transparent box always in front of the viewer, like a window they are always looking at. How do I place this in front of the viewer?   Do I have to calculate where the viewer is at all times, draw a box, and change it accordingly,   or,   Can I place a box in the scene, (kinda like a layer), that no matter where I look, It will stay in the same place?   Thanks for your input.....   Zak
