I am having trouble solving the "position within a bitmap" problem with java3D. It appears that the method used for getting that kind of information is to capture the image in a back buffer, resize the image to a 1x1 size that views the clicked pixel only, then call the readRaster function to get the DepthComponent. They you choose the top value off the DepthComponent for the value of the selected item (since the map is selectable) and use that for the Zbuffer value. Once you have the screen x,y,z, then do a transformation of coordinate space (setting y to reference the correct direction) and multiply by the inverse of the transform our coordinates were generated by. Unfortunately, it looks like the only way to access the readRaster function is to be in immediate mode rendering. If I wanted to use Immediate Mode, I would use opengl right from the source. So it defeats the purpose. Is there another way to get at this? It seems that the idea was totally left out of the compiled implementation. This is a fairly common problem, it surprises me that it is so obtuse. Is there anyone with a different methodology that works here?? I would appreciate the help...
