In order to make a Menger-sponge isosurface i want a function that will
give me a triangular wave.
I tried using floor, but I get a plane at x=0 where it should be empty
space. Is this a bug? What would be a better way to get a triangle wave?
isosurface {
function {
abs(x/6+3-floor(x/6+3)-.5)-2/6
}
contained_by { box { -3,3 } }
pigment { color rgb x }
}
