Segment2D Class

Syntax

C++

class Segment2D;

File

Description

Represents 2D Segment objects.

Remarks

Segment2D is a convex 2D curve given by two points and a bulge value. If the two points coincide, the segment has the estCoincident type. If bulge==0, the segment is a straight line segment; otherwise it is a circular arc, and bulge=tan(Angle/4).
