Member Function Documentation

areColinears()

bool ArcCSegIntersector::areColinears ( ) const

virtual

By construction, no chance that an arc of circle and line to be colinear.

Implements INTERP_KERNEL::EdgeIntersector.

getPlacements()

void ArcCSegIntersector::getPlacements ( Node *  start, Node *  end, TypeOfLocInEdge &  whereStart, TypeOfLocInEdge &  whereEnd, MergePoints &  commonNode  ) const

virtual

to call only if 'areOverlapped' have been set to true when areOverlappedOrOnlyColinears was called

Implements INTERP_KERNEL::EdgeIntersector.

areOverlappedOrOnlyColinears()

void ArcCSegIntersector::areOverlappedOrOnlyColinears ( bool &  obviousNoIntersection, bool &  areOverlapped  )

virtual

See http://mathworld.wolfram.com/Circle-LineIntersection.html _cross is 'D', the computation is done with the translation to put back the circle at the origin

Implements INTERP_KERNEL::EdgeIntersector.

References INTERP_KERNEL::EdgeArcCircle::getRadius(), INTERP_KERNEL::EdgeIntersector::identifyEarlyIntersection(), and INTERP_KERNEL::Node::sign().

getIntersectionsCharacteristicVal()

std::list< IntersectElement > ArcCSegIntersector::getIntersectionsCharacteristicVal ( ) const

virtual

The size of returned vector is equal to number of potential intersections point. The values are so that their are interpretable by virtual Edge::isIn method.

Implements INTERP_KERNEL::EdgeIntersector.
