Hi All, I found several posts for this question, but no one has an answer. I tried to do it myself. Right now, I wrote a class to draw a rubber-wand like window on the graphics model, so I can get the 4 screen coordinates for the window, combined them with the eye point, I can construct a pyramid.
So, now the problem comes to how to compute the intesection between an infinite pyramid with any scene model? It's not an easy problem for me, since J3D doesn't has this kind of PickShape. Does anyone have a good way to do it? Considering this widely used picking operation, does Sun have any plan to include anything like PickPyramid in the future?
