This repo is just an experimental project that I have been doing, in order to learn Rust.

Screenshots

• 5 samples per pixel
• 6320 triangles

How to use

In main.rs instantiate camera and a scene (in this order) and add to-be rendered objects to scene.objects array. Then run cargo run --release.

NOTE: As teapot model has thousands of triangles to render, the process might take a lot of time. You can simply remove this 3D model by commenting out the lines where it is added to scene.

//scene.objects.push(Box::new(obj));

TODO: The wasm integration will make usage easier.

Features

The following program has support of:

• Diffuse and specular materials
• Lights (3 types)
• Reflections
• Shadows
• Camera and viewport control (FOV, orientation)
• Antialising (by multisampling)
• Simple .obj file reading
• AABB optimization
• Multithreading
• Builder pattern for constructing objects

To do

• Integration with WebAssembly
  • Interaction with objects
• Gamma correction
• Refraction
• Textures

It was in turn inspired by several projects listed below:
