Hi Kelvin: Thank you for your instruction. I checked the PureImmediateStereo.java file and found that the line: public static String defaultSharedStereoZbuffer = Boolean.TRUE.toString();
is there correctly. My graphic card does support the stereo. I am not perfectly sure whether through OpenGL standard API, but as a newly purchased GeForce2 MX card, it should work that way, am I right? After running the program, I did see: This machine support stereo, you should see a red cone on the left and green cone on the right. I also checked all my driver configurations (changed each of them each time, to see whether the problem could disappear or be influenced). I could not find any thing which is related to this problem. Can you please tell me what graphic card you are using? For my card, I have to patch the card driver (nv4_mini.sys) with SoftQuadro to get the card working with stereo mode. Do you have better device which support stereo and does not need to be patched? Fixing this problem is crucial to my image so let me describe this problem again here: When I run the PureImmediateStereo.java file I see "This machine support stereo, you should see a red cone on the left and green cone on the right." first. I did see the red and green cones to different eyes through a glasses. However, I also saw flashing (or flickering) of part of the cone images on the top of the images. The size of the flashing image increased from the top of the cone until they reached the full size and then started again. If you did not see what I described here, I may need to try another card which is better than the one I am using. Thank you a lot for your great help! G.B.
