DXR Path Tracer
A DXR path tracer with OptiX denoising. 5 months worth of research, trial & error as part of a project to learn and understand DirectX Raytracing & raytracing concepts.

This is a graduation project for my study at the Breda University of Applied Sciences. It is by far my most proud piece of tech that I've built at the time of writing.

Starting off this project, I had little clue about raytracing or pathtracing. This entire project has been a giant learning experience. I've spent countless hours researching, programming, bug fixing and drank many litres of coffee to get to this point.
The video above will explain it all much better than I can with text. Have a look!
