There's a sample image below which it says "First results, 83 lines of code." Is that the total number of source lines in that version of the raytracer? Wow! I mean, the sample doesn't look especially beautiful, but 83!! WOW!!
Hi there, I wrote this ray tracer. Thanks to everyone for your positive comments. I don't have a copy of that version any more, but it was 83 lines from start to finish, including the scene description and dealing with Java to display the image. No AA or multi-CPU support, but point-light sources and reflection, and a little general-purpose vector library.
There was probably more code on each line than is typical Lisp style, though.
There are some techniques in the code for getting good performance (as good as Java at least) for mathematical routines - the JVM is the limiting factor rather than Clojure.
I hope it helps to show that Clojure is a practical language, since the concepts in it are going to be important in the near future. Also, if anyone is impressed by shiny spheres and wants to talk of entrepreneurial things, email's on the project page. :)
