A simple multi-threaded ray tracer written in Rust

Ray Tracer Engine

This is a ray tracer engine based on the books Ray Tracing in One Weekend and Ray Tracing: The Next Week by Peter Shirley.

The engine is written in Rust, adapted from the C++ version of the book. A few changes have been made from the provided implementation:

• Multi-Threading support
• SAH (Surface Area Heuristic) for building the BVH tree
• Various optimizations for improving the run-time performance

Future plans:

• Add support for other objects
• Add support for more textures
• Improve performance using Monte Carlo and other methods
