I don't have an answer to your question unforunately. I just wanted to say
we all feel your pain when it comes to documentation. Between the API doc
and the usage doc there is probably, what, 500 pages of docs? Yet it still
isn't enough. I wouldn't want to write it myself. The best thing we can do
is keep submitting solutions and explanations to Justin Couch to add to the
FAQ pages.

Subject: [JAVA3D] Projection Matrix
I am trying to compute the projection matrix Java3D uses based on the
information in mainly the View class, but it also depends on the Canvas3D,
Screen3D, Physical Body, and Physical Environment (and possibly more?).
My frustration is building up based on poor documentation and complicated
policies (many, many different policies and combinations). I was
wondering if anyone has already done this? Or possibly the someone who
actually did this could give us the code (or pseudo-code) to calculate it?
Also, is it possible to get the projection matrix? I have tried to set up
my viewing policies, then change to Compatability Mode to get the VpcToEc,
but by changing modes, it resets it to the identity matrix.
Thanks in advance,
Blaine
