The roughness of the turbulence determines the roughness of the
changes to the displacement amount. Low values smoothly change
the displacement amount. High values roughly change the
displacement amount, which produces more "kinky" changes.
Internally, there are three module::Perlin noise modules
that displace the input value; one for the @a x, one for the @a y,
and one for the @a z coordinate. The roughness value is equal to
the number of octaves used by the module::Perlin noise
modules.
Sets the roughness of the turbulence.
