compareTo
Defines a comparison operation on DepthSegments which orders them left to right. Assumes the segments are normalized.The definition of the ordering is:
- -1 : if DS1.seg is left of or below DS2.seg (DS1 invalid input: '<' DS2)
- 1 : if DS1.seg is right of or above DS2.seg (DS1 > DS2)
- 0 : if the segments are identical
- The logic does not obey the
invalid reference

- Specified by:

in interfaceComparable
- Parameters:
obj
- a DepthSegment- Returns:
- the comparison value
-
compareX
Compare two collinear segments for left-most ordering. If segs are vertical, use vertical ordering for comparison. If segs are equal, return 0. Segments are assumed to be directed so that the second coordinate is >= to the first (e.g. up and to the right).- Parameters:
seg0
- a segment to compareseg1
- a segment to compare- Returns:
