Projection Faster and Uncompressed

u/@noel

I love this one and I follow the logic, until the z & w performing. I know it's a bitwise AND operation on z and w, but I don't actually grasp it.
u/@noel

I mean on this one: x.fillRect(i, j, 1, (z & w) / w)
u/joeytwiddle

Here (z & w) / w is the height of the rectangle. If that height is less than 1, then the canvas anti-aliasing renders a grey pixel, instead of a black one.
u/@noel

Thanks u/joeytwiddle Now I think I get it. (z & w) ensures that the value of z remains within the range of the canvas width 'w', and the dividing by w normalizes the height value. Great trick!
