From: "John Tsiombikas" To: "Ian Mapleson" Date: Tue, 9 May 2006 07:30:19 +0300 Hello again, you wanted a benchmark that would take some time huh? Well, take a look at this :) Keeping in mind that the raytracer is dead-simple, brute-force, etc etc. Increasing the object count is a good way to make this much more complicated... I've made a small scheme program to generate the regular sphere-fractal recursively (mainly because I wanted something to do to learn scheme actually :) So you might as well try it out if you happen to have a scheme interpreter (like guile). here it is: http://nuclear.dnsalias.com/tmp/sfract/gen_fract.scm and here are a few pics: http://nuclear.dnsalias.com/tmp/sfract/ I run it as: $ ./guile -s gen_fract.scm | ./c-ray-f -s 1024x768 -r 5 >out.ppm and with 5 iterations (change the 2nd argument to the (generate ...) call near the bottom if you wish to change them) it took about 14 minutes on my Athlon64 :) -- John Tsiombikas (Nuclear / Mindlapse) nuclear@siggraph.org http://nuclear.demoscene.gr/
