Helix -- from Wolfram MathWorld

for , where is the radius of the helix and is a constant giving the vertical separation of the helix's loops. which is a constant. In fact, Lancret's theorem states that a necessary and sufficient condition for a curve to be a helix is that the ratio of curvature to torsion be constant.

Helix - Wikipedia

A circular helix, (i.e. one with constant radius) has constant band curvature and constant torsion. A curve is called a general helix or cylindrical helix if its tangent makes a constant angle with a fixed line in space.
