Jack,
That's great, I was playing around with the settings, (Had 0.05 in there)
and it didn't seem to do anything, but yeah, those values help a lot.
There's one more problem.
The shutter glasses do not switch on using J3D only. I had a colleague help
me out, and we have looked at the stereographics examples.
There's the blue line index that is used to get the galsses in synch with
the program and switch them on however , is there another way? Has Java3D
got some form of implementation for this?
Also, we noticed that the stereographics demo switchs on the Glasses if you
called a AfxMessageBox (in C) in the intialisation, and did not required a
blue line! We are not sure why, probably thread related.
Does anyone have any ideas on this, and has anyone implemented the blue line
index if it's not accesible from within J3D? The idea is to place a seperate
frame at the bottom of the screen that is updated in time with the program
and vertical interrupt, but not sure if there is an access method to get the
vertical interrupt in Java (couldn't find one in C without resorting to
DirectX or OpenGL). The full screen mode will probably be too slow for
stereo rendering for the larger projects.
Thanks for your help,
Sky

Subject: Re: [JAVA3D] Stereo Viewing with OpenGL and W2K
When you say the image's disparity grows (to quite a large extent), do you
mean that you see 2
images that do not converge to form the stereo image? I always change the
default setting for the
interocular distance with
physicalBody.setLeftEyePosition( new Point3d(-.0033, 0.0, 0.0));
physicalBody.setRightEyePosition(new Point3d(+.0033, 0.0, 0.0));
the default is .033 which dosnt work with the normal simpleuniverse setup.
