TITLE: Tibanna Gas Mine NAME: Henry Wagner COUNTRY: USA EMAIL: henryw@panix.com WEBPAGE: http://www.panix.com/~henryw/ TOPIC: Flight COPYRIGHT: I SUBMIT TO THE STANDARD RAYTRACING COMPETITION COPYRIGHT. JPGFILE: tibanna.jpg ZIPFILE: tibanna.zip RENDERER USED: POV-Ray 3.0 msdos TOOLS USED: Notepad, and some custom written C programs RENDER TIME: 4 hours 30 minutes 23 seconds HARDWARE USED: Micron P150, 32 Megs IMAGE DESCRIPTION: This image was inspired by the work of Ralph McQuarrie in the book "The Illustrated Star Wars Universe". The main object is a Tibanna gas refinery (pages 144-145) and the balloons floating by are from page 164. I started by making it a daylight scene with clouds but the background seemed to take away from the objects so I switched to a night image. I tried putting in a starfield (lots of tiny spheres) but with radiosity these stars didn't show up so I took them out. Radiosity adds some amazing lighting effects, the gas refinery seems to glow inside. I used a big area light off to the left side of the image to create the smooth shading. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: I created several programs to generate scene objects inorder to add some randomness. The source is included in tibanna.zip. GENWIN.CPP: This program generates the little windows as boxes. There are a total of 15 sets of windows in the scene. GLGTOWER.CPP: This program randomly positions the light towers that hang below the big center section of the gas refinery. DETAIL.CPP: This program randomly generates small detail objects, boxes, cylinders, cones, spheres, and cylinders with halos on top, that are places on the lower portion of the gas refinery. GENSTAYS.CPP: This program generates all the thin cylinder supports for the balloon. To generate all the necessary include files you need to run BUILD.BAT The other files included in tibanna.zip are: BALLOON.INC: The object definitions for the balloon object BALLOON.POV: Test scene file for the balloon object TIBANNA.INC: The object definitions for the Tibanna Gas Mine TIBANNA.POV: Main scene file used to create final image LGTOWER.POV: Test scene file for the light tower object LGTOWER.INC: The object definitions for the light tower object GLGTOWER.EXE: Compiled version of GLGTOWER.CPP GENWIN.EXE: Compiled version of GENWIN.CPP GENSTAYS.EXE: Compiled version of GENSTAYS.CPP DETAIL.EXE: Compiled version of GENSTAYS.EXE The final image was rendered with these parameters: c:\povray3\povray +Lc:\povray3\include +Itibanna.pov +Otibanna.tga +FT +v -x -p +W800 +H600 +B1000 +r9 +QR +A0.300 +J1.000
