Method Details
-
getStart
Get the start point of the segment.- Returns:
- start point of the segment
-
getEnd
Get the end point of the segment.- Returns:
- end point of the segment
-
getLine
Get the line containing the segment.- Returns:
- line containing the segment
-
distance
Calculates the shortest distance from a point to this line segment.If the perpendicular extension from the point to the line does not cross in the bounds of the line segment, the shortest distance to the two end points will be returned.
Algorithm adapted from: Thread @ Codeguru- Parameters:
p
- to check- Returns:
- distance between the instance and the point
