Ray Tracing in One Weekend: From Zero to Stunning Images

This tutorial teaches you how to write a ray tracer in a weekend using C++. Starting with basic PPM image output, it progressively introduces concepts like rays, cameras, spheres, and materials, culminating in a renderer capable of producing anti-aliased images with diffuse and metallic materials. The tutorial covers vector math, ray-sphere intersection, surface normal calculations, material abstraction, and depth of field, providing clear code examples and beautiful renderings. Even without prior programming experience, you can follow along and build your own ray tracer.
