  • loktar: Done from scratch instead of following the patterns I had in my original was able to golf it down to an acceptable size.

  • pavel: Still seems like this is a matter of perspective. You are chosing a perspective in which the core is always fixed, even though the motion I am describing specifically involves holding the two sides fixed and rotating the core... In my reference frame the core is rotating. So what if the core contains more parts than the side pieces when you take the cube apart?
  • 13thptr: that escalated quickly

  • rodrigo.siqueira: Artfarnaa, it is possible to make super fast, see this pure JS fast implementation: https://csl.name/mandelbrot/ There are many tricks specifically created to calculate Mandelbrot Set (e.g. avoid calculations in a rectangle inside the main set because all pixels are white and calculations in this white area is slower than other parts), but no speed optimization were used here because of space constraints. Some tricks to make it faster: do not use time variable to do calculations (because it is max 60 fps), do not plot each pixel, but store them in an array and plot at once using c.putImageData(img)...
  • KilledByAPixel: There is one way to make it very very fast. I just made a quick shader of it for you! https://www.shadertoy.com/view/wtjGz3
  • artfarnaa: Thanks guys, great inspiration.
