EMAIL: beliaev@utu.fi NAME: N.B. TOPIC: Physics & Math COPYRIGHT: I SUBMIT TO THE STANDARD RAYTRACING COMPETITION COPYRIGHT. TITLE: how do I model phenomenon X COUNTRY: Finland WEBPAGE: RENDERER USED: POV-Ray 3.01 for Windows 95 TOOLS USED: nothing special: .TGA to .JPG, .ZIP, etc. RENDER TIME: over 25 hours HARDWARE USED: Pentium 166MHz 16Mb IMAGE DESCRIPTION: I really find this round's topic interesting, but it's a bit too narrow, and it gives advantage to those studying/working in the fields over the others (I mean pure artists like me). Actually, I used to have a lot of physics and math in my college days, but time has passed and my mind seems to be free from both disciplines.... This image is absolutely non-scientific (or pseudo-scientific), and it's definitely inspired by Truman Brown's Woild images. If you find this image off-topic, please consider: 1."scenes that show theories in action", 2. an allegory... DESCRIPTION OF HOW THIS IMAGE WAS CREATED: The text was written in POV-Ray text editor. "Trial and error"raytracing was used instead of graph paper. Most of the objects were made as *.inc files (sometimes nested), so that it was easy to add/remove them to/from the main scene and raytrace only portions of the image. I used 320x240 window (without aa) for test renderings. Present image is raytraced with radiocity on. All objects are my own (and made for this IRTC round). They are included in the .ZIP. Please feel free to use them. Objects: 1. "Lake" is a height_field from a smoothened Mandelbrot fractal image. 2. "Liquid_in_the_lake" is a box with normal_map: wood, spiral2 and bumps. 3. "Spiral_object" is made of cylindrical blobs (n=2500) in a while loop. 4. "Female_figure" is made of CSG of multi-element blobs. There are a number of control parameters to change the position of arms and legs. However, because of lack of time the model is not "fully-functional". 5. "Car" is made of CSG of multi-element blobs, wheels are CSG of cylinders, torii (?!) and boxes, seats are superellipsoids (hardly seen on the picture). In .ZIP there's a rendered picture of the whole car included.
