An Euler spiral is a curve whose curvature changes linearly with its curve length (the curvature of a circular curve is equal to the reciprocal of the radius). Euler spirals are also commonly referred to as spiros, clothoids, or Cornu spirals. Euler spirals have applications to diffraction computations. They are also widely used in railway and highway engineering to design transition curves between stra… WebThe clothoid spline has G2 continuity. The result should be used in geometric optimzation, so squared distance (x p - x c) 2 + (y p - y c) 2 may be used. If there is no analytic solution, can anyone give a good suggestion to an iterative solution. Definition of clothoid and splines: Clothoid is also called Cornu spiral or Euler spiral.
