Hi,
That looks like the matrix, but I think you can apply it just once, either
above all the transform groups or to the projection matrix.
You might have to be a bit careful as there were bugs with all but the latest
version of Java3D that said things about non-affine or non-congruent matrices.
Also reflections can cause java3D to get a bit confused about the
left-handedness / right-handness of things so when I tried something similar I
had to play around with settings like CULL_NONE and BACKFACE_NORMAL_FLIP or
similar.
From,
Greg.
