getEdgeDistance method
Computes the "edge distance" of an intersection point along the specified input line segment.
@param segmentIndex is 0 or 1 @param intIndex is 0 or 1
@return the edge distance of the intersection point
Implementation
double getEdgeDistance(int segmentIndex, int intIndex) {
double dist = computeEdgeDistance(intPt[intIndex],
inputLines[segmentIndex][0]!, inputLines[segmentIndex][1]!);
return dist;
}
