Detailed Description

Defines an PHLV5 edge.

Role: The PHLV5_EDGE class acts as the primary output of the API api_phlv5_compute. Each PHLV5 edge is essentially a wrapper to an underlying ACIS EDGE. It contains a pointer to the CURVE of the EDGE, a pointer to a list of PHLV5_SEGMENTs (containing visibility information for that EDGE), and a pointer to a polyline representing the EDGE in 3D space. The modeling data with visibility start and stop parameters can be used to display the hidden line representation in an end user application or, for better performance, the polyline data can be used directly.

Constructor & Destructor Documentation

PHLV5_EDGE::PHLV5_EDGE	(	CURVE *	Curve = 0,
		BODY *	Body = 0,
		FACE *	theFace = 0,
		PHLV5_SEGMENT *	Seg = 0,
		float *	Point = 0,
		int	n = 0,
		int	MySense = 0,
		EDGE *	Edge = 0,
		PHLV5_OCC *	occ = 0,
		logical	persistable = TRUE
	)

C++ initialize constructor requests memory for this object and populates it with the data supplied as arguments.

Role: Applications should call this constructor only with the overloaded new operator, because this reserves the memory on the heap, a requirement to support roll back and history management.

Parameters:

	Curve	A curve.
	Body	Body.
	theFace	Face.
	Seg	Segment.
	Point	Polyline points.
	n	number of points.
	MySense	Sense.
	Edge	ACIS EDGE pointer
	occ	PHLV5_OCC pointer.

PHLV5_EDGE::PHLV5_EDGE

(

PHLV5_EDGE const &

e

)

C++ copy constructor.

Parameters:

e

PHLV5_EDGE to copy.
