The problem from the Java 3D side is that we can't port our native layer to the quirks of each vendor's drivers. We have to use the standard D3D and OpenGL mechanisms for obtaining stereo resources. That said, Nvidia and ATI are the leading PC card manufacturers, and if we had even a hint from them about how to access the stereo buffers in their cards we could probably put in some special-case code for them. But there is no public information as far as we can tell, and we don't have the cozy relationships with them that the game developers do. The standard mechanisms do require separate front, back, and depth buffers for each eye. It may be that this is too expensive in terms of video memory for consumer-level cards, especially when the most important use of video memory, from a gaming point of view, is for textures. The approach that Nvidia seems to take is to customize their stereo drivers to support specific applications through some sort of interposing mechanism. This suggests that their stereo support is too fragile, cumbersome, or non-standard for them to expect game developers to develop stereo applications themselves. -- Mark Hood =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
