getIntersectionAlongSegment method
Computes the intIndex'th intersection point in the direction of a specified input line segment
@param segmentIndex is 0 or 1 @param intIndex is 0 or 1
@return the intIndex'th intersection point in the direction of the specified input line segment
Implementation
Coordinate getIntersectionAlongSegment(int segmentIndex, int intIndex) {
// lazily compute int line array
computeIntLineIndex();
return intPt[intLineIndex![segmentIndex][intIndex]];
}
