Summary
| Description |
English: A logarithmic spiral with arc-length parametrization that doubles its distance from the origin every full turn (a=1, k=(ln 2)/(2π), s=0 to 28). Also selected first derivative vectors, which are unit tangent vectors and corresponding second derivative vectors, which are curvature vectors perpendicular to their tangents and are reduced to half their length with each full turn. |
