Ray Tracing Engine
As part of the practical exercises for Computer Graphics Winter 2019-20, I incrementally built my own ray tracing system, which then was used to generate a high-quality rendering for the end-of-term rendering competition. This beautiful image of fireworks was created using the above source code for submission to rendering competition. Refer here for its full webpage.
