Ray Tracing in One Weekend

Ray Tracing in One Weekend book series, done in Rust

Features

• Multi-threaded CPU raytracing of spheres
• Global/indirect illumination
• Multiple materials, image textures, and noise textures
• Only dependencies aside from std are for randomness (currently rand and rand_chacha)
• Serialization of PPM files for render output
• Deserialization of PPM files for texture input

Usage

Run using cargo run --release, choose scene by entering a number when prompted, wait for render to finish, then view the resulting render.ppm in the root directory of the project

Example renders

Future plans

• More materials, including emitters, volumetrics
• Triangle/quad primitives
• Parsing of some simple 3D model format
• Optimizations (e.g. surface area heuristic for BVH)
