HIGH QUALITY and VERY FAST! Targeting speed again... Seemed to run faster with changing count by 1, instead of changing by 2 and going from the incenter to each corner every time. Only supports res of 1. (Otherwise things look wonky) All code by me! Thanks to the internet for pretty much all the math used here. Thanks to @Chrome_Cat for the idea of using custom blocks to hold multiple placeholder values and probably speeding things up a bit. Also, I got the idea of how to fill triangles from a lot of great triangle fillers out there that were made by smarter people. Comparisons on my computer: Dolphin Tri Fill Improved (this one) is about 17,000 per second at 1000 per frame! @-Rex-Test- and @Geotale filler is about 12,000 per second at 1000 per frame. https://scratch.mit.edu/projects/509029922/ Azex triangle filler is about 13,000 per second at 1000 per frame. (I think this one is recommended by 3Dgas?) https://scratch.mit.edu/projects/885002848/
