rs_pbrt

rs_pbrt is a Rust crate that implements the physically based rendering techniques from the third edition of the PBRT book. This project provides a Rust counterpart to the original C++ code, enabling high-quality rendering with the safety and performance benefits of Rust.

rs_pbrt focuses on physically based rendering (PBR), a technique that simulates the physical behavior of light to produce highly realistic images. This approach is essential for creating accurate and visually appealing renderings.

Extensive documentation is available to help users understand and utilize rs_pbrt. The latest documentation covers various aspects of the library, including usage, features, and examples.

Several test scenes are provided to demonstrate the capabilities of rs_pbrt. These scenes include complex models and lighting setups, showcasing the renderer's ability to handle detailed and realistic scenarios.

To build rs_pbrt, use the following commands:

> cargo build --release --no-default-features
> ./target/release/rs_pbrt --help

Running the command with --help will display available options and usage information:
