3d graphics float "benchmarks"

MiniLight: a minimal global illumination renderer (re)written in Scala, OCaml, Python, Ruby, Lua, Flex and C++ : http://www.hxa.name/minilight/ 

I think it would be interesting to have a D version and compare for the float performance and maybe even lines of code.

There is another similar "benchmark" here:

I'm too much of a D noobie myself to attempt this.
