Implementation of "Raytracing in one weekend" and "The next week" by Peter Shirley (http://in1weekend.blogspot.com/2016/01/Ray-tracing-in-one-weekend.html)
Partially inspired from this excellent article "Accelerated Ray Tracing in One Weekend in CUDA" by Roger Allen (https://devblogs.nvidia.com/accelerated-ray-tracing-cuda/)
Since this uses CUDA you will need nvcc. Just use make run.
