Toy Raytracer

Toy raytracer I wrote in C++ back in 2015.

Features

• Accurate treatment of reflective, refractive, and diffuse surfaces, including Fresnel interactions.
• Depth of field
• Adaptive sampling (samples increased on noisy pixels)
• Probably some more things that I forgot about since 2015

Requirements

Works out-of-the box on Linux with g++ installed. Shouldn't be too hard to run on Windows.

Usage

Basic Setup

1. Run ./compile.sh. All this does is compile all .cpp files in the ./src directory.
2. To render a sample image, run ./render.sh. This may take a few minutes (go and have a coffee). The output will be written to output.bmp.
3. To render an animation, run ./animate.sh. This may take a nontrivial amount of time. The output will be unceremoniously dumped to several dozen .bmp files.

Customization

• All setup is located in main.cpp (for stills) and animation.cpp (for animations).
• Definitions for polyhedral meshes (i.e. the cube) is stored in meshData.h.
