A single-day quick implementation of the Ray Tracing in One Weekend book. The goal was to get something reasonably clean working fast, and I believe I achieved that:

Features checklist:

• PPM image creation
• Ray-sphere intersection, normals (and all the basic linear algebra and geometry. Vector boilerplates is mostly the nalgebra crate)
• Boxed anti-aliasing
• Clean movable vector camera (TODO: Clean everything and store proj matrices instead)
• Naive and Lambertian diffuse material
• Metallic material
• Dieletrics
• Defocus blur
