I looked at the testcases under 4900656, and I suspect one of the the common
themes to be TransformGroups under an OrderedGroup. In my case, I don't have
any TGs under the OrderedGroup, and all of my OrderedGroups do work fine
until I introduce a SharedGroup a couple of levels above the OrderedGrou
There is a flag in the PolygonAttributes to flip the normals if the
transform contains a reflection. However, that one works only with the
opengl version, and not with the directx version of j3d.

Well, I have both CULL_NONE and normalflip always set to true since I need
to see 2 lit sides always. And the problem is that setting
backFaceNormalFlip to true kills both front and back lighting on the
reflected geometry. Setting the flip flag to false, produces correct front
side lighting, but th
We have released a new version, 441, of "Jun for Java".
The major changes since the version 431 includes:
* JunOpenGLFluxModel is updated to Jun490 and can generate
images and/or movie.
* Support multi languages. Window titles, menu labels,
dialog messages are displayed in
What I'm doing in my program, is to detect if the transform contains a
reflection or a non-homogeneous scaling, and if yes, I'm duplicating the
branch below it and manually flip and rescale all the normals so that after
applying the transform they will point to the correct direction and have the

The problem with reflection appears to be that the CCW winding and the
*transformed* normal direction are inconsistent, unlike the case of rotation.
Consider, for example, a quad that is on the -ve xy plane and rotated 180
deg. about the y-axis. The result, coordinate wise, should be identical to

Hi folks,
Does anyone out there understand the view transfomation mechanics/policy
when rendering in mixed mode?
I have a mixed-mode app. My drawing method gets called by Canvas3D's
"postRender()" method. I get the GraphicsContext3D from the Canvas3D,
and I draw a Shape3D that I believe is sized
