Rusty Raytracer

Rusty Raytracer is a simple ray tracing project implemented in Rust, inspired by Peter Shirley's "Ray Tracing in One Weekend". This was my first project ever using Rust, I used it as a way to learn the language and explore foundational concepts in computer graphics.

Features

• Materials: Supports Lambertian (diffuse), Metal (reflective), and Dielectric (refractive) materials.
• Customizable Camera: Allows for different camera angles, positions, and field of view (FOV).
• Random Sampling: Implements random sampling for realistic rendering.
• Scene Composition: Renders scenes with multiple spheres and materials.

Example Output

The raytracer is capable of rendering scenes like this:

Getting Started

Prerequisites

• Rust (edition 2021 or later)
• A basic understanding of Rust and ray tracing concepts is helpful but not required.

Installation

1. Clone the repository:

git clone https://github.com/L3chuga/rusty-raytracer.git
cd rusty-raytracer

2. Build the project:

cargo build --release

3. Run the ray tracer:

cargo run --release

The rendered image will be saved as image.ppm in the project directory. With the default configuration (low resolution and low detail) it takes around 11 seconds to render a full image in my low spec laptob. You can freely change the constants in main.rs to get better images at a larger rendering time cost. You can use online .ppm viewers to see the finished images but I recommend using a vscode .ppm extension as this way you can see the image being generated in real time.
