Hi Barry,
Unfortunately, my organization blocks where ever it is that hosts your images, so I can't see what you are describing. I will check it out this weekend on another computer. It does sound a little thought intensive. If you give up on this approach let me know. I'll tell you the way I solve it in 2-dimensions using mostly trig. It also makes taking into account the view rotation possible if that's important to you.
Thanks,
Minion
