EMAIL: wmp506@bham.ac.uk NAME: Bill Pragnell TOPIC: Nature COPYRIGHT: I SUBMIT TO THE STANDARD RAYTRACING COMPETITION COPYRIGHT. TITLE: A Reminder of Home COUNTRY: Great Britain WEBPAGE: None at present RENDERER USED: POVray 3.0 TOOLS USED: No others RENDER TIME: 4-5 hours HARDWARE USED: Pentium 166, 16MB RAM IMAGE DESCRIPTION: This image may appear unrelated to the topic at first glance, but I didn't want to go for the obvious subject matter, eg forests animals etc. We take the natural world for granted, but at some point in history it may not be so accessible to us. This image depicts an arboretum on the moon or some similar lifeless body, constructed by the inhabitants to remind them of their origins. IMAGE CREATION DESCRIPTION: The image was created solely using POVray 3.0, hand-coded using with no other tools but those inherent in the description language. The cliffs and ground are height-fields built up from the POV bozo and granite texture maps. The planet (earth, perhaps?) in the sky is coloured with a four-layer texture, the starfield and nebulae in two layers. All the man-made bits are lots of CSG using torii and cylinders, textured with the crand grain finish. I recently noticed that raytraced objects look much more realistic with slightly rounded edges; there are no really sharp edges in real life. The plants and tree are simpler than they look - the only complicated bit is the leaves; they were made with sneaky CSG invloving spheres. Note - cliffs and rocky terrains are difficult to custom-build using POV textures, especially only using a PC. Most of the parsing was taken up by the height-fields.
