Realtime global illumination is fascinating. To gain more experience in this area, I have been developing several hobby GI projects over the last few years (https://lnkd.in/etBv-vF).

My latest project (shown in attached video) is a Constructive Solid Geometry realtime pathtracer that utilizes temporal and spatial filtering techniques to eliminate noise in screenspace. In each frame each pixel samples the rendering equation integral (several bounces) and accumulates the results via a Moving Exponential Average. The output is then denoised via a spatial filter (inspired by SVGF).

The pathtracer supports realtime changes to geometry and lighting. In addition to diffusely bounced light, I added support for volumetric fog (extinction + in-scattering), day/night cycle, simple color grading, and a subtle vignette effect. It runs at 60fps on a Macbook Air (no discrete GPU).

Four years ago I applied for a position at Unity Technologies and was rejected mostly due to lack of theoretical background. They kindly suggested that I formally studied computer science.

I followed their advice and enrolled for computer science at Copenhagen University. After working my ass off for three years, I completed my bachelor's degree a few weeks ago 🎉!

Also, I received an offer from Unity Technologies as a full-time graphics engineer which I accepted 🎉. I am starting next month. I like to think that this shows how patience, focus, and hard work can make dreams come true 🤓.
