This is fun!

I was going to try to draw a circle but was missing sin/sqrt. Then I thought of using a lookup table but got stumped.

Do you have any pointers for drawing a circle?

I'm looking at demo #4 (https://susam.net/fxyt.html#XYpTN1srN255pTN1sqD) to see where the circular shapes are coming from.

doesn't need to be accurate, could do something like this (distance + treshold) :

smaller with dup :

PS: fun tool !

Oh, thanks!

X^2 + y^2 > z^2 ? 1 : 0

Was also gonna jump in with the old way of doing circle boundaries, which can be done all integer: https://en.m.wikipedia.org/wiki/Midpoint_circle_algorithm
