I have a pair of stereoscopic images, e.g. left.jpg and right.jpg
and want to "render" these images into a stereo Canvas3D.
Using Open-GL this is very easy:
...
glDrawBuffer(GL_BACK_LEFT);
glDrawPixels(width, height, GL_RGBA, GL_UNSIGNED_BYTE, leftBuffer);
glDrawBuffer(GL_BACK_RIGHT);
glDrawPixels(width, height, GL_RGBA, GL_UNSIGNED_BYTE, rightBuffer);
glutSwapBuffers();
...
I tried something like the code below, but this does not work
at all. All kinds of manually configuring the rendering pipeline
(immediate mode) result in some unexpected
behaviour.
...
GraphicsContext3D g3D = ...
g3D.setStereoMode( GraphicsContext3D.STEREO_LEFT );
g3D.draw( raster_left );
g3D.setStereoMode( GraphicsContext3D.STEREO_RIGHT );
g3D.draw( raster_right );
...
Does anybody know example code for this problem or if this is not
possible at all with j3d?
My configuration (WindowsNT, jdk 1.3, j3d1.2, Diamond Fire GL 1000 Pro)
works well in stereo for the examples in j3d using the standard rendering
pipeline
(despite the known bug that the z-buffer for the right eye is not cleared)
Thank in advance for any hint.
