Just a quick note to let anyone interested that the source code to my work-in-progress Haskell raytracer and photon mapper is now available at:
I'm currently mid way through debugging and optimising the photon map solution. It works, though it takes 10 minutes or so on my MacBook Pro.
When run it will output the following image:
To build the program you just need the latest Haskell Platform and the bmp package from cabal.
I'm still a beginner at Haskell so some of the code may not represent the most idiomatic or best practice Haskell. If anyone has any advice, comments or constructive criticism, I'm keen to hear it at email@example.com.
(I plan to make the package Cabal compatible soon).
