subdivide

public void subdivide(Segment s0,
                      Segment s1)

Subdivides this Linear segment into two segments at t = 0.5. can be done with getSegment but this is more efficent.

Specified by:

subdivide in interface Segment

Parameters:

s0 - if non-null contains portion of curve from 0->.5

s1 - if non-null contains portion of curve from .5->1

Subdivides this Linear segment into two segments at given t.

Specified by:

subdivide in interface Segment

Parameters:
