The spiral1 pattern creates a spiral that winds around the
z-axis similar to a screw. When viewed sliced in the x-y plane, it looks like
the spiral arms of a galaxy. Its syntax is:
pigment {
spiral1 Number_of_Arms
[PIGMENT_MODIFIERS...]
}
The Number_of_Arms value determines how may arms are
winding around the z-axis.
As a normal pattern, the syntax is
normal {
spiral1 Number_of_Arms [, Bump_Size]
[NORMAL_MODIFIERS...]
}
where the Number_of_Arms value is a required
parameter but the float Bump_Size which follows is
optional.
Note: The comma is required especially if Bump_Size is negative.
The pattern uses the triangle_wave wave type by default but may
use any wave type.
