A Monte Carlo Ray Tracer (Path Tracer) written in Rust.
This project was developed as an educational exploration of ray tracing and global illumination. The implementation is inspired by the book Ray Tracing in One Weekend.
- Path Tracing
- Monte Carlo global illumination
- Multiple bounces (recursive rays)
- Materials
- Diffuse (Lambertian)
- Perfect reflections
- Glass / dielectric refraction
- Emissive materials (light sources)
- Acceleration Structure
- Bounding Volume Hierarchy (BVH)
- Fast traversal for ray intersection tests
- BVH construction and intersection approach adopted from https://jacco.ompf2.com/2022/04/13/how-to-build-a-bvh-part-1-basics/
- Scene Import
- glTF scene loading
- Triangle mesh rendering only
- Parallel Rendering
- Multithreaded rendering using rayon
- Image rows rendered in parallel across CPU cores
Ensure you have Rust installed.
Build the project:
cargo build --release
Run the renderer:
cargo run --release
Rendering parameters such as resolution, sample count, can be configured in the src/lib.rs file.
