A simple ray tracer implemented in Rust for learning and generating images from scene descriptions.
rust-raytracer is a simple ray tracing engine written in Rust, based on the "Ray Tracing in One Weekend" tutorial. It generates photorealistic images by simulating light rays interacting with 3D scenes defined in JSON, adding features like texture mapping and parallel rendering. The project was created to learn Rust while building a functional graphics tool.
Developers learning Rust who want a hands-on project in computer graphics, or those needing a lightweight, customizable ray tracer for educational or prototyping purposes.
It offers a clear, extensible codebase for understanding ray tracing fundamentals, with performance optimizations like multi-core rendering and practical features like JSON scene descriptions, all in a memory-safe language.

Uses Rayon to leverage all CPU cores, significantly speeding up render times—for example, reducing a frame from 21 seconds to 2.5 seconds as shown in the README.
Supports image textures for objects and backgrounds, enabling realistic scenes like Earth and moon surfaces, with clear examples provided.
Scenes are easily defined and modified via JSON files, allowing quick prototyping without code changes, as demonstrated in the sample scene.
Based on 'Ray Tracing in One Weekend', making it an excellent resource for learning Rust and ray tracing algorithms from scratch.
Lacks advanced ray tracing features such as motion blur, depth of field, or physical-based rendering materials, making it basic compared to commercial engines.
Relies entirely on CPU parallelization with Rayon, which is slower than GPU-based alternatives for complex or high-resolution scenes.
The author admits the code may not be idiomatic or good, which could pose challenges for maintenance or extension by other developers.
