TITLE:Petronis Towers COUNTRY:USA WEBPAGE:N/A RENDERER USED: POV-Ray for Windows Version 3.02 watcom.win32 (Pentium optimised) TOOLS USED:Moray for tower models and initial placements, Paintshop Pro v3.0 for preparation of imagemap. RENDER TIME:30 sec parse, 6 min 15 sec render HARDWARE USED: 233 MHz Pentium-class, 64 Mbytes RAM, Win 95 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 . 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.
