When we specified many of these things, we were trying to keep open the possibility for different types of implementations. We also wanted to make sure we didn't put in contraints that made it impossible to add more advanced features in the future. It is true that the specification states that t

Hello! After asking around on this list for hardware acc on laptops I finally bought an IBM a20p, ATI mobility 16 MB, 512k, w98, and I do get hardware accelleration on it, but of course the standard is not as high as on my ordinary PC (450 mhz PIII, 512k, 32 MB videocard). And I have to downscale

Hi Boris I have tried what you said but it doesn't work. when I try to rotate the object it seems  to want to rotate (jerk) but it comes again to the initial position. may  be I have something wrong. I changed the  processStimulus(Enumeration enumeration) methode of the MouseRotate classe as foll

The rotation/orbiting about a Center ( x, y, z ) seems to be the best solution for you, however if you absolutely use the default behavior, wouldn't it be possible to create a new locale at the coordinates mentioned and attach the viewplatform to that locale ? We should be able to see the objec

Hi Mohammed! It is esier then you describe. The A matrix is actually constant. The center of the object should be calculated only once, when the object is just created , and no transformation is aplied to it yet. All further transformations are present in T matrix, so what this formula does is f
