I doodled with writing a raytracer once. Shitty it was, but I did it in Haskell and with minimal knowledge of how it's properly supposed to be done.

Pic related.

>> No.18  

Mine's in Haskell too!

>> No.19  

You're in luck then. CSG is surprisingly simple to do in Haskell. As you can see from the green sphere in my shot -- it's been carved up with two more spheres. Fancy detail: the change in shape can be seen in one of its shadows...

>> No.20  

Just out of interest -- how long does yours take to produce a 640x480 image? Mine took around five seconds for the test scene in >>17, singlethreaded (don't know how to parallelize Haskell programs) on a socket 939 AMD64 X2 4400.

Amusingly enough it takes like twenty seconds to compile the Main module with the "-O" flag on. Haskell is serious bizness.

>> No.21  

>>20
5 seconds without antialiasing, 23 seconds with, on a 2.33GHz core2duo.
How many lines of code is yours? Mine is around 280 right now..

>> No.22  

987, but I use two newlines between toplevel definitions and the thing is split up into five or six modules.
