IMAGE DESCRIPTION: Based on the tallest buildings in the world Petronis Towers, Kuala Lampaur, 
(according to the international architects governing body), this image demonstrates what a nice
fisheye shot from 2 meters above the topping ball on the spire would look like.  Shot emulates 
about a 5mm fisheye on a 35mm camera (140 degree spread).  Just the classic city highrise shot -- 
except from the top <grin>.  Uses focal blur instead of antialiasing. 

DESCRIPTION OF HOW THIS IMAGE WAS CREATED: tower models created in Moray using CSG from a 
cross section in Scientific American article.  Details of railings and "sky-bridge" gleaned 
from web images.  Background imagemap is patched together from numerous chunks of air photos 
(1 meter per pixel resolution) gathered from www.terraserver.microsoft.com and stitched 
together (and blended / touched up) in PSP.  Initial camera and model placement was in Moray, then
exported and code hand-tweaked for fisheye lens.  As a final fix, the groundplane was converted 
to a large diameter hemisphere (instead of a large flat "cube" )to emphasize the fish-eye effect.    
imagemap is not included in .zip because of size.  I tried bot AA and focal blur and had better luck 
with JPEG'd focal blur instead of AA.
