I wonder if anyone can help with the following. I want to display a 3D grid of lines and some other objects in Java3D, and to let the mouse select either grid intersection points or these other objects embedded in the grid. If the mouse IS NOT on an object I want to select the nearest grid point if it is within some maximum 2D distance of the cursor. If the mouse IS on an object I would prefer to select the nearest of any grid points nearer the user than the object if that point is within that same distance limit, otherwise the object. Can anyone advise me on how to do this or point me to an open source example that I could use or adapt? Ray Chan p.s.
