TITLE: Are we taught the truth ? NAME: Franck Angella COUNTRY: France EMAIL: angella@goelette.tsi.u-bordeaux.fr WEBPAGE: http://goelette.tsi.u-bordeaux.fr/perso_angella.html TOPIC: SCHOOL COPYRIGHT: I SUBMIT TO THE STANDARD RAYTRACING COMPETITION COPYRIGHT. JPGFILE: fabook.jpg ZIPFILE: fabook.zip RENDERER USED: Povray 3.0 TOOLS USED: TerrainMaker RENDER TIME: 2 hours for 'Past', 5 hours for 'Future' HARDWARE USED: PPro200, 256Megs IMAGE DESCRIPTION: School has always existed, and will exist for ever. What we learn is different and so is the way we learn. But maybe one day people will forget what the truth was, and learn false things about us and our ancestors. This image shows what people may learn about prehistoric people in a few years. They may learn that there were schools in caverns too. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: This image is made of 2 images: -The first picture (grotte.pov) represents the cavern. Walls are heightfields generated with TerrainMaker. A picture of real prehistoric drawing is mapped on it. The picture comes from Lascaux, France. Tables are created with some superellipsoids. The flame is a simple halo. The most difficult problem was to add lights which could correspond to the shadows on the wall mappings. -The second picture(fabook.pov) uses the cavern generated before with a mapping on the first page of a book made by a parametric Bezier patch object. The transparent page uses a normal bump pattern. Most of the other objects are transparent and filtering light. Shadowless texts were added inside these transparent objects. Pens are transparent too with halo inside. The whole scene was rendered with radiosity on.
