Thank you so much @richard, @jwunderl, @AqeeAqee, and whoever else (like other members on the MakeCode team) contributed to this release! This runs super smooth now!

This will also allow for other 3d rendering systems to be developed, not having to work pixel-by-pixel, greatly improving performance! While my project most likely still won’t run on hardware due to the other math, these changes allow for much better performance in the sim! I could see many great uses for filled polygons in the future, and I’m excited for what will be possible in the future!
