CURRENT UPDATED FILLER: CAN FILL 1000 TRIANGLES IN A SINGLE FRAME FILLS 20K TRIANGLES/second ON A HIGH-POWER COMPUTER already 4K TRIANGLES per second... ON A LAGGY CHROMEBOOK WITH NO INTERNET almost as fast (maybe surpassing) Azex, but sometimes unreliable, as the screen can refresh while drawing the triangles Legacy Centroid filler: This triangle filler was slow--it filled 1000 triangles in about 4-5 seconds. (subject to device CPU, one computer took 3.5 sec while another took 0.5 sec on average)
The new, improved method fills the incircle then proceeds to fill into the corners with decreasing pen sizes. My (legacy) method was to make smaller and smaller triangles based on a precision factor P, centered at the centroid. (Precision was hand-set, another method would be to use the circumradius as precision)
