Well I probably butchered the formula but here is what I made:
#declare MinRad = pi/2;
#declare MaxRad = (3*pi/4)*10;
#declare Test =
union {
#while (MinRad < MaxRad)
object {sphere {<0,0,0>, 0.1 translate <cos(MinRad)*1, sin(MinRad)*1,
MinRad/10> pigment {Red}}}
#declare MinRad = MinRad + 0.01;
#end
}
object {Test rotate x * -90 translate <0,-2,0>}
This created a spiral but always the same distance from the center. I was
trying to make something that would get closer to the center as it moved up
or down.
What did I do wrong? (I'm sorry my math skills are really poor...)
