Threaded Raytracer

A comprehensive implementation of a multi-threaded CPU raytracer built in Rust, based on the "Ray Tracing in One Weekend" series. This project explores advanced rendering techniques, performance optimization, and Rust's capabilities for systems programming. ## Key Features - **Multi-threaded Rendering**: Utilizes Rust's `rayon` crate for parallel pixel processing - **SIMD Optimizations**: Leverages vector operations for improved performance - **Progressive Rendering**: Real-time preview of rendering progress - **Material System**: Supports various material types including metals, dielectrics, and emitters - **Scene Description**: Flexible scene definition through code ## Technical Highlights The raytracer implements several advanced techniques: - **Monte Carlo Integration**: For accurate lighting calculations - **Importance Sampling**: Optimized sampling strategies for different materials - **BVH Acceleration**: Bounding Volume Hierarchy for faster ray-object intersections - **Memory Optimization**: Careful data structure design for cache efficiency ## Performance Results Through careful optimization, the implementation achieves: - 4x speedup through multi-threading - Additional 2x speedup through SIMD operations - Maintains clean, readable code thanks to Rust's type system The project demonstrates Rust's strengths in systems programming while exploring the fascinating world of computer graphics and raytracing algorithms.
