This is the implementation of the ray tracing algorithm on the CPU

Build

The supported platforms are Windows and Linux. On Linux you need to manually install GLFW 3. After that you can build the program doing

make

Usage

You need to run the renderer from the command line providing it the proper arguments:

./ray_trace.exe --scene scene_0.txt --threads 16 --init-scale 2

This will open a window with the rendered scene. You can more around with WASD and change the camera direction with the mouse.

You should use a number of threads equal to the number of CPU cores. The --init-scale lowers the initial resolution of the scene when moving the camera and can be any power of two between 1 and 16 (1, 2, 4, 8, 16).
