I haven't looked at the code yet, but Justin Couch mentioned he had some
fustrum methods in one of the J3d packages.

Subject: [JAVA3D] frustrum
hi all,
I'm asking myself how to retrieve the 6 planes of the viewing frustrum
in Java3D ?
In OpenGL I used:
glGetFloatv( GL_PROJECTION_MATRIX, xxx );
glGetFloatv( GL_MODELVIEW_MATRIX, yyy );
for gettting the Projection- and the Modelview so I can compute the
frustrum planes according to a formula..
O.k. I guess ModelView is LocalToVWorld, but how about the Projection
Matrix ?
Are the Front,-BackClipDistance, FieldOfView of the View-Object
sufficient, so no Projection Matrix is needed ?
greetings
