Evalutes an helix at a parameter.

Parameters
  • t (float) – Parameter

  • a (float) – Constant

  • b (float) – Constant

  • c (float) – Constant

list – The (x, y, z) coordinates.

Notes

An interpretation of the constants a and b are the radius of the helix is a, and the slope of the helix is b / a.
