"Kithrup" by Steve Sloan EMAIL: sloan@geosim.msfc.nasa.gov NAME: Steve Sloan TOPIC: Science Fiction COPYRIGHT: I SUBMIT TO THE STANDARD RAYTRACING COMPETITION COPYRIGHT. RENDERER USED: Povray for Windows Version 3.0 (PovWin 3.0) TOOLS USED: "Terrain Maker" was used for the heightfield, and "Wc2pov" by Keith Rule was used to convert the 3DS dolphins (from 3D Cafe) to POV 2.0 format. I have lost the name of the artist who made the dolphin models, but thank him/her for their use. RENDER TIME: 3h 53m 09s HARDWARE USED: 486 DX4-100, Windows 3.1 with Win 32s IMAGE DESCRIPTION: This image is based on a scene from the novel _Startide_Rising_ by David Brin. According to the cover blurb: "The Terran exploration vessel Streaker has crashed on the uncharted water-world of Kithrup, bearing one of the most important discoveries in galactic history. Above, in space, armadas of alien races clash in a titanic struggle to claim her. Below, a handful of her human and dolphin crew battles armed rebellion and a hostile planet to safeguard her secret-- the fate of the Progenitors, the fabled First Race who seeded wisdom throughout the stars." The damaged Streaker landed on the ocean floor of Kithrup, so the "crewfen" (the dolphin members of her crew) could make repairs while the ship was in hiding. Each fin has a work harness, with manipulator arms for repair work, and water-jet impellers for fast propulsion. In this scene, Captain Creideiki (a fin) inspects one of the ship's detector bouys, while a school of metallic-scaled native fish swims by. Streaker looms in the background. Note the two JPEGs included in Kithrup.ZIP. They were my inspiration for this scene. Fin_Sled.JPG, a picture of a dolphin wearing a work sled, was scanned from an illustration by David Cherry, and Streaker.JPG, a line drawing of Streaker, was scanned from the book. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: I coded everything but the dolphins directly into POV, using CSG functions like union, difference, etc., and primitives like spheres, cylinders, boxes, and tori. Individual parts were constructed, tested, then placed into the final scene. Note the school of fish. I used while loops to create a regular 3D grid of individual fish, to simulate the natural orderliness of fish in "formation", but added a slight random offset to each fish's position, to keep their "ranks" from looking too perfect. I used metallic textures for each fish, like "New_Penny" and "Soft_Silver", because the world of Kithrup has much more metal than Earth, and its seas are full of metal salts, which are incorporated into the scales and bones of all its creatures.
