[JAVA3D] Confusion

[Demetrius]

There is something very basic I think I'm missing about the Java3D view model.  It seems to me that all coordinates must be between -1 and 1 (unless a scale trans form is used to).  Meaning if I take a box with vertices at (-0.5,0.5,0),(0.5,0.5,0),(0.5,-0.5,0), and (-0.5,-0.5,0) and add it to a transform group than has it's translation set to (2,0,0) the box out of my viewing volume.  Even though my backClipDistnace is 10000, and my front clip distance is 0.1.  Can anyone explain what I'm missing?   Thanks in advance!
