Drawing / Painting as Many Rects as Possible (Still WIP, feel free to comments or contribute!)

Moved here

Fastest Rectangles

Some thoughts:

  • How many ways can you draw rectangles in a browser (eg. dom, css, 2d canvas, svg, webgl)
  • How is the fastest (most number of) rectangles can you draw with each approach?

Task:

  • Paint random rectangles for 5 seconds, find out how fast each approach takes.

Hello, it's me, I was wondering
If after all these years you'd like to meet to go over everything
They say that time's supposed to heal, yeah
But I ain't done much healing
Hello, can you hear me?
