# The Business Card Ray Tracer ![png version of the ppm output image](rgl.png "6.out | ppm -e9t | topng") This is a more readable adaptation of Andrew "aek" Kensler's original 1337-size ray tracer written in plan 9 C. You can read an updated version of his [here](http://eastfarthing.com/blog/2016-01-12-card/). I also recommend you take a look at Paul Heckbert's “A Minimal Ray Tracer”, Graphics Gems IV.
