Hi Kelvin,
First of all thanks for accepting and filing bug#4632388. Secondly,
I filed a couple of reports in Sun's Bug Database in late December
and since then haven't heard anything from Sun. So I though maybe
it's a good idea to post reports to this mailing list.
Thanks,
-Oleg Pariser @ NASA-JPL Multimission Image Processing Lab

>A DESCRIPTION OF THE PROBLEM :
>In Immidiate mode, J3DGraphics2D.drawAndFlushImage(...) is
>ignoring
>GraphicsContext3D.setStereoMode(GraphicsContext3D.STEREO_LEFT)
>setting and renders to both eyes(i.e. stereoMode
>STEREO_BOTH). What is interesting, if I set stereoMode to
>STEREO_LEFT, then call GraphicsContext3D.draw(...), then
>call J3DGraphics2D.drawAndFlushImage(...), the result is
>correct: image is drawn only to left eye.
>But if I set stereoMode to STEREO_LEFT and call
>J3DGraphics2D.drawAndFlushImage(...) *without* calling
>GraphicsContext3D.draw(...) first, the image gets drawn to
>both eyes.
>
>P.S. In describing the problem I used STEREO_LEFT, but the
>same is applicable to STEREO_RIGHT
>
>STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
>1.Compile and run submitted test program which requires two
>imageFileNames to run.
>2. Notice that images gets rendered to both eyes, even
>though the expected result is image#1 rendered to
>STEREO_LEFT and image#2 rendered to STEREO_RIGHT
>
>EXPECTED VERSUS ACTUAL BEHAVIOR :
>Expected result: After calling
>GraphicsContext3D.setStereoMode(GraphicsContext3D.STEREO_LEFT)
>J3DGraphics2D.drawAndFlushImage(...) renders only in left
>eye.
>Actual result: J3DGraphics2D.drawAndFlushImage(...) renders
>in both eyes.

>This bug can be reproduced always.
