August w4 2023

After much testing, we finally traced the root cause of our simulation stability issues and have a handle on it. Due to how object generation works…

August w3 2023

Investigated alternative directions for rigid body processing - found working solutions, but I expect to restructure physim work from scratch down the line. Discovered an oversight…

August w2 2023

3D Voronoi incircle-based spacing math so that first-order tori to be centered as well as possible, and second-order tori can be smaller (thus decreasing metamaterial mesh…

Made some tools to identify where kinks with the geodesics / graph traversal were, and tried a few naive approaches to solving them. This stretched my…

March w3 2023

Moved to lean more on graph traversal algorithms as geodesics for SOL placement information, which yielded a rapid improvement in maile quality.

March w2 2023

Following some advice I got from an investor friend, I worked on making my deck more data-backed and professional, including some hefty data analysis of every…
