Catenary curve through three points
Hangs a catenary curve from two points with the thrid directing its fall.
Files for Grasshopper 0.7 - 0.8.x:
20101018_catenary_arch_2.ghxParameters:
- Point: Start of curve
- Point: A point on the curve
- Point: End of curve
Outputs:
- Curve: The Catenary curve
Notes:
Curves are drawn in the xz-plane. If you want the curve in another plane, the points need to be rotated into the xz-plane and then the curve needs to be rotated out into the desired plane.
Uses a hill-climbing algorithm to pass curve through the third point. Hill climbing stops when the tolerance is reached or the max iterations are reached.
