simple sdf "showcase" move ur mouse, you get the closest distance from all the shapes! green = positive distance (outside of any shape) red = negative distance (inside of any shape)
a Signed Distance Function (SDF) basically shows any distance from a point to a shape the currently supported shapes are rectangles, circles, and line segments, which with union and subtraction can make pretty complex shapes. SDF functions from Inigo Quilez Referenced a BUNCH of code from @falkimore all other code by yours truly
