RtRs

Simple ray tracing & rasterization engine written in rust.

Features

Ray Tracing:

• Rendering quadrics: sphers, cones, cones (with slabs),
• Rendering meshes (passed as .obj files). Also precomputing vertex normals
• Bounding Volumes Hierarchy
• Full camera movement + zoom
• Precomputed mesh normals
• Object rotations
• Parallel execution
• Lambertian/Phong shading
• Gouraud/Phong shading
• Antialiasing via supersampling (via distributed ray tracing)
• Soft shadows (via distributed ray tracing)
• Reflections + glossy reflections (via distributed ray tracing)
• Refraction & attenutation

Rasterization:

• Mesh rasterization
• Object rotation
• Lambertian/Phong shading
• Gouraud/Phong shading
• Texture mapping with stripe effect
• Backface culling
• Full camera movement + zoom
• Simple antialising (via supersampling)
• Clipping
• Camera movement

How to run the code

You need to install Rust on your system and then just type the command:

cargo run --release

The binary file will be located at target/release/rtrs. There is also a binary attached which is located at rtrs (Note: compiled on OS X Catalina 10.15.6).

Core dependencies

• tobj to load .obj files
• nannou to open a window and detect key press events, which is an analog of OpenFrameworks for Rust language
• image to save an image
• rayon which provides easy-to-use parallelism for Rust
