Animation and raytracing are two capabilities of computers that interests me. Raytracing is a technique in which a computer program produces a photo-realistic picture from a spesification of objects and their surfaces, lights, atmosphere etc. You supply the specification, the program generates or renders the picture. Being a full time student with little spare time and money, however, I have had to limit my exploration. I found it so fun, however, that I soldered a FPU into my PowerBook 165 to boost rendering-performance. This page represents a summary of my explorations so far. POV-Ray and myself is responsible for the triangle to the right.

My own humle creations
All the QuickTime movies are in cross-platform format.
Rolling glassballs.This movie, of some rolling glassballs (432 kb) in QT format, was one the first things I made with POV-Ray. The animation is meant to be looped, and looks best in 16 bit or more colours. Then you really can see all the reflections and refractions!
Tryggve/Sunniva Morph.The morph Try_Sun.mov (915 kb) or Try_Sun.MPG (360 kb). This is two friends of mine, morphed to each other with Morph 2.0.1. At least they were friends... 8^) I can't say much about the quality of the MPEG version. It looks like crap on my computer, but I have no MPEG supporting hardware.
Flying logo.The animation of the L.A.G logo (697 kb) or logo.MPG (292 kb). Maybe a more approperiate name would have been Ego.mov... 8^) Only the QT version have sound. The flying "marble" letters were done with POV-Ray. The warped crossfade to the standard logo was done with Morph 2.0.1. The sound was produced with Soundeffects 0.9.2 and SoundEdit. So it's not Myst exactly, but what I could do with the tools available. The movie and sound were mixed together in the absolutely faboulus QuickEditor 3.6.
Early modules.I used POV-Ray to make a model of some particle detector modules I worked with at CERN. This is an early picture of them (52 kb). Kind of... uninteresting.
Later modules.A picture of the same modules with more life (48 kb). Some bumps here and there, and more subtle lightning makes the difference.
Rotating modules.A QT movie of the rotating modules (995 kb). A first version of this movie was made before I got the FPU. Each frame took approx 6 hours to render, and there were 60 of them... This one, however, was made after having soldered an FPU onto the daughterboard. It containes 120 slightly bigger frames, rotating the modules 3 degrees between each frame. In addition, I used a minimum of anti-aliasing (supersampling) when rendering. Really makes a lot of difference! The job took a weekend, with each frame grabbing a small half-hour!
Reflecting refraction.A picture of two spheres, one with a mirror surface and the other one of glass, lying side by side on a partly reflective, tiled floor. Sort of a classic Ray-tracing Show Case.
Lunar Sector.The 832x624 (16") ray-traced picture "Lunar Sector" (235 kb). This is my first shot at the unavoidable space-theme. A quite simple picture done in POV-Ray. No re-touching is done, the picture is the direct output from the renedering. Incidently, I used genuine surface-maps of the Earth and Moon. You can see that the Moon's surface have been 'stretched' a bit too much. I could have PhotoShopped away some of that, but I didn't want to to any post-processing.
