TITLE: Freemish Crate COUNTRY: USA WEBPAGE: www.graphicilluminations.com RENDERER USED: POV-RAY Version 3.1e TOOLS USED: Demo version of Rhino 3d. Text created with Photoshop 5 RENDER TIME: 4 minutes 9.0 seconds (249 seconds) HARDWARE USED: P1 233mhz 64Mb RAM IMAGE DESCRIPTION: Years ago I read about a special crate that one could build AND it would produce an actual photograph of a Freemish crate. You may remember the Freemish crate from school, it's known as an "undecidable" illusion. Although the crate is cube, it is impossible to build. Also, years ago, when I started ray tracing I always thought it would be fun to take a "picture" of this special freemish crate but never got around to it. Then I saw this months IRTC topic and I knew what I must do. The bad part is I did not catch this until the 24th. I am pleased with the results but I feel this model has the potential to be a very stunning render. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: The actual objects in the model was created with the demo version of Rhino 3D. Then exported as a POV file with the objects each in their own INC file. The rest was created in POV-RAY. I would say the two hardest aspects of this render were cutting the crate to give the proper illusion and the placement of the light. The cutting took quite a while. The one thing you find first is the fact that the camera angle or perspective cannot change once you cut the crate. So you have to set up the whole scene before you start cutting. The one issue I was not prepared for was the light. I really wanted to use shadows but it took some time to find a place for the light so that the shadow did not give away the illusion to quickly, ie: the shadow had gaping holes in it where I did the cutting.
