Hi Oleg,
Bug 4633701
- J3DGraphics.drawAndFlushImage(...) is ignoring GraphicsContext3D.setStereoMode()
and
4633700 - J3DGraphics2D.drawAndFlushImage(...) doesn't work well with
J3DG2D.copyArea()
is filed for them.
We're looking to resolve all 3 bugs in v1.3 beta2.
Thanks for your bug report.
- Kelvin

>>synopsis: J3DGraphics.drawAndFlushImage(...) is ignoring
>>GraphicsContext3D.setStereoMode()
>>description: FULL PRODUCT VERSION :
>>java version "1.4.0-beta3"
>>Java(TM) 2 Runtime Environment, Standard Edition (build
>>1.4.0-beta3-b84)
>>Java HotSpot(TM) Client VM (build 1.4.0-beta3-b84, mixed
>>mode)
>>
>>FULL OPERATING SYSTEM VERSION :
>>SunOS monolith 5.7 Generic_106541-16 sun4u sparc
>>SUNW,Ultra-5_10
>>
>>
>>
>>EXTRA RELEVANT SYSTEM CONFIGURATION :
>>Java 3D(TM) 1.3 Beta 1
>>Java Advanced Imaging(JAI) v1.1.1
>>
>>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.
