Hi again,
I think I found thesource of the problem and unfortunately a possible BUG
(don't know if its a bug in the driver of the graphics card or in j3d) when
using the GraphicsContext3D class in mixed stereo mode. I have an object in a
scene graph which get rendered correctly for both eyes. But I'm also rendering
2 planes with different colors in immediate mode via the GraphicsContext3D. One
plane should be in the image of the right eye, one plane in the image of the
left eye. The planes are centered at (0,0,0) and parallel to the xy-plane (no
modeltransforamtion is applied to the GraphicsContext3D). The plane for the
right eye is renered when Canvas3D . renderField( Canvas3D . FIELD_RIGHT ) is
called and the plane for the left eye when Canvas3D . renderField( Canvas3D .
FIELD_LEFT ) is called. The renderField method is overriden by a class
inherited from Canvas3D. The plane for the left eye is rendered in the correct
position.
BUT the plane for the left eye is located to the right and a little bit back
(negative z) from (0,0,0).
Can somebody from SUN comment on this. Testcase can be made available.
I'm using Win NT4.0 SP 6a, j3d OpenGL version 1.2.1_01, Java SDK 1.3.1, Fire
GL2 graphics card.
regards
Paul
