distanceIndexedPointBToSegmentAC MethodStatic

Return perpendicular distance from points[indexB] to the segment from points[indexA] to points[indexC].

  • Extrapolation options when the projection is outside of the fraction range [0,1] are:
    • false ==> return distance to closest endpoint
    • true ==> return distance to extended line segment
  • There is no index checking!
