This is a prototype triangle filler based on stamping. It starts off extremely slowly but gradually speeds up to ~65% of the speed of my pen-based tri filler. I plan to switch from vector costumes to high-resolution bitmap costumes to solve this issue. I also plan to optimize the code, as this tri filler is only ~20% faster than my pen-based tri filler even when not stamping. This also uses ~3 GB of VRAM on my system with an AMD graphics card, so good luck running this on integrated graphics or on a smartphone.
