Detailed Description

Implements construction algorithms for a line segment in 3D space. Makes a segment of Line from the 2 points <P1> and <P2>. The result is a Geom_TrimmedCurve curve. A MakeSegment object provides a framework for:

• defining the construction of the line segment,
• implementing the construction algorithm, and
• consulting the results. In particular, the Value function returns the constructed line segment.

Constructor & Destructor Documentation

GC_MakeSegment() [1/4]

GC_MakeSegment::GC_MakeSegment	(	const gp_Pnt &	P1,
		const gp_Pnt &	P2 )
