toy-raytracer
A learning exercise.
This is adapted from the raytracer code in Chapter 9 of "ANSI Common Lisp", by Paul Graham.
I've been adding my own improvements to the code, where I think I can make it clearer, less redundant, and take advantage of Clojure's abstractions. Some of this has made for clearer, more concise code, particuarly in the places where I can use Clojure's built-in data structures and destructuring; other places it's been a more rocky transition, such as adapting to Clojure's object model (my limited understanding of it, at-least).
To run:
$ lein run | pnmtopng > foo.png
(This assumes you've installed the netpbm utilities.)
