c-trace

Toy raytracer written in C

Traced images are sent to standard output and can either be redirected to a file or piped to an image viewer or other program that supports reading an image from standard input.

An example scene file is given in example.esc, and the image below was generated by the command

c-trace -g800x600 -s400 -b4 example.esc > example.png
