Raytracer in Rust

A rudimentary raytracer in Rust.

Goals

• Working raytrace implementation with basic shapes
• Different shading materials with Lambert, Metal and Glass
• Scene, Camera and Render API
• Shapes including Planes, Spheres, Triangles, Disks and Rectangles
• Antialiasing, gamma correction and working aspect ratio
• Depth of field with aperture and focus distance settings

TODOs

Updated as of 12/13/2018

• Add an Axis-Aligned Bounding Box system (AABB tree collision detection)
• Add in mesh-based intersections to be able to read .OBJ format
• Voxel-raytracing
• Multi-threading with multiple-producer single-consumer
• Adding in .X3D format support to import Blender export data
• Lights, including spot-lighting and ambient lighting
• Camera animation / rendering multiple frames

Layout of Code

This raytracer library is broken up into several smaller modules to modularize it as much as possible.

• raytracer::math contains all raw math functions and libraries for computing 3-dimension vectors
• raytracer::geometry contains all shapes and AABB-related tools
• raytracer::shading contains lights and materials
• raytracer::rendering contains tools for creating and rendering scenes

Install

Clone and run the code with

git clone https://github.com/sleibrock/rust-raytracer
cd rust-raytracer
cargo run
