TITLE: chess COUNTRY: UK WEBPAGE: RENDERER USED: povray 3.6.1 TOOLS USED: MicroEmacs 3.11, gnuchess, ffmpeg, mpeg2enc, Linux (Slackware) CREATION TIME: Final render ~12h HARDWARE USED: Athlon 11000 VIEWING RECOMMENDATIONS: ANIMATION DESCRIPTION: A chess battle. DESCRIPTION OF HOW THIS ANIMATION WAS CREATED: I saved a simple/short chess game (gnuchess vs a version of gnuchess altered to only think 1 move ahead), and wrote a simple conversion program to make a Povray include file (game.inc) which has an array for each move and a list of the piece(s) moved/captured. The moves were then grouped into a number of scene files (title + sc001.pov -> sc019.pov) containing 1 or moves, the camera, look_at position and aperture were stored in separate file (camera.inc), most of the camera positioning between 'cuts' utilised splines. My early attempts had problems with MPEG encoding artifacts when using VCDish bandwidths, my solution was to use focal blur to cut down the detail where it was not required. The sky was created using an agate pattern with colour values sampled from some photos of the sky, the surrounding hills are simple height maps (not detailed, but are never in sharp focus). The pieces themselves are mostly SOR's with some CSG for the knight and king/queen. Most of the mpeg encoding was done with mpeg2enc, but the final pass for the IRTC entry was done with ffmpeg (2 pass) "vcd_final.sh" I created a very basic sound track (64kbit mono) consisting of a few basic sounds as it seems to enhance the video. If I had more time, I would work on the arm movements for the sword/mace, the physics of king falling and maybe improve the sound.
