Detailed Description

A ConstraintSegment2 can belong to more than one ConstraintGraph2 object, thus it is unoriented. But the ConstraintGraph knows the orientation of its ConstraintSegment2's.

Member Function Documentation

◆ getCIS()

ConstraintInsertionStrategy GEOM_FADE2D::ConstraintSegment2::getCIS ( ) const

Returns: the constraint insertion strategy (CIS) of the present object

◆ getSrc()

Point2* GEOM_FADE2D::ConstraintSegment2::getSrc ( ) const

Returns: the first vertex

◆ getTrg()

Point2* GEOM_FADE2D::ConstraintSegment2::getTrg ( ) const

Returns: the second vertex

◆ insertAndSplit()

Point2* GEOM_FADE2D::ConstraintSegment2::insertAndSplit ( const Point2 & splitPoint )

Splits the ConstraintSegment2 (which must be alive) at splitPoint.

It may be impossible to represent a point exactly on a line segment using floatingpoint arithmetic. Therefore it is highly recommended to split a ConstraintSegment2 object not just be inserting points into the triangulation but using the present method. It does not require that splitPoint is exactly on the segment.

Note: A splitted ConstraintSegment2 is dead and it has two child segments (which may also be dead and have children). The class is organized as a binary tree.

◆ isAlive()

bool GEOM_FADE2D::ConstraintSegment2::isAlive ( ) const

Returns: TRUE when the object is alive, FALSE otherwise

◆ split_combinatorialOnly()

bool GEOM_FADE2D::ConstraintSegment2::split_combinatorialOnly ( Point2 * pSplit )

internal use only (unless you do something very unusual)
