Ray Tracer
Description
This is a basic shapes CPU ray tracer, written from scratch. It is one of my 2nd year projects at university and the main purpose was applying and improving my math knowledge. I have a strong background in mathematics from my high school, so I did pretty well for the time given, considering I had no previous experience with graphics at all.
I have implemented the following features:
Rendering of sphere, plane and cube; Blinn-Phong shading model; Hard and soft shadows; Multiple light sources and colors; Ambient light/Global illumination; Light attenuation; Anti-Aliasing; Transparency; Reflections; Refractions; Bounding Volume Hierarchy
Project Details

75 FOV
Project Setup
Here is my Visual Studio solution setup. Apart from the ray tracer code, I have my own math library with custom Vector2 and Vector3 classes, as well as a unit testing library (See images on the right).
Bellow, you can see the main pixel loop of the ray tracer.

Throughout the development I have adhered to the agreed upon coding standards of our university and maintained proper code structure. Here are some examples of my code.
