This is a simple implementation in C of the ray tracer presented in Peter Shirley’s books with some enhancements like multi-threaded rendering.
First of all, you will need make and the pthread library to build
rt. If you don’t have it or you don’t want multi-threaded rendering,
you can go comment everything related to this in rt.c
and change the run rule in the Makefile to use the
commented command instead.
make # Just to create rt executable
make run # Create rt executable and run it
