TITLE: City in the Snow COUNTRY: United Kingdom WEBPAGE: www.rayjay.clara.co.uk RENDERER USED: WinMegaPov 0.4 TOOLS USED: Paint Shop Pro for creating Ident text height field WebGraphics Optimizer for image conversion RENDER TIME: 18 hrs as a Background task HARDWARE USED: Intel PII/450MHz 128MB IMAGE DESCRIPTION: Population and environmental pressures have created the need for cities to be built in locations previously thought too harsh to sustain large populations. Here we see a typical new mountain city. Like most harsh environment cities, the majority is underground, but the need to see blue sky means that a grid of grey rectangular office/accomodation blocks nestle in the curve of the mountainside. Also visible is the large fusion reactor that powers the city and its outpost (you can see a quad-jet performing a visual inspection of the data/power line connecting the outpost), and the quad-jet port which provides the only physical link to the rest of the world. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: The picture relies heavily on features added to POV 3.1 by Nathan Kopp's MegaPov. The landscape is a Ridged Multi-Fractal IsoSurface (included in the Zip file is an image of the landscape alone). All buildings except the far reactor and the landing pad of the quad-jet port, are CSGs of boxes, spheres and cylinders. The reactor, quad-jet landing pad and quad-jets are blobs. Almost all textures were applied via slope_maps with a bozo sub-texture used to stop the snow forming straight lines on the buildings. Rendered with radiosity so that the shadows are not black, which increases the blue in the image and drops the perceived temperature by a few degrees. The only post-processing done on the image was to convert from tga to jpeg. Zip file includes full source.
