Software ray-tracer written in C. Inspired by, The Ray Tracer Challenge by Jamis Buck.
To build run meson setup build, then meson compile -C build.
To run the tests, run meson test -C build.
- Criterion 2.4.2 (Optional, only required for the tests)
The project roughly follows the structure laid out by the book, deviating where deemed necessary.

Source code for this demo is located in test/sphere.c.
It shows two spheres in 3D space rendeded by casting rays on a canvas.
No shading or light simulation is done, thus the lack of "depth".
Source code for this demo is located in test/lighting.c.
It shows a sphere that is lit by a point light.
Source code for this demo is located in test/camera.c (dd88842).
It shows three spheres surrounded by two "walls" and a "floor".
Source code for this demo is located in test/shadows.c.
It shows three spheres surrounded by two "walls" and a "floor", illuminated by two light sources.
Source code for this demo is located in test/planes.c.
It shows three spheres, sitting on a plane, illuminated by three colored lights.
