bool SegSegIntersector::areColinears (  )  const

retrieves if segs are colinears. WARNING !!! Contrary to areOverlappedOrOnlyColinears method, this method use an another precision to detect colinearity !

Referenced by INTERP_KERNEL::QuadraticPolygon::buildArcCirclePolygon().

bool SegSegIntersector::haveTheySameDirection (  )  const [virtual]

Must be called when 'this' and 'other' have been detected to be at least colinear. Typically they are overlapped. Must be called after call of areOverlappedOrOnlyColinears.

Implements INTERP_KERNEL::EdgeIntersector.

void SegSegIntersector::getPlacements ( Node start,
Node end,
TypeOfLocInEdge whereStart,
TypeOfLocInEdge whereEnd,
MergePoints commonNode 
) const [virtual]

Precondition start and end must be so that there predecessor was in the same direction than 'e1'

Implements INTERP_KERNEL::EdgeIntersector.

void SegSegIntersector::areOverlappedOrOnlyColinears ( const Bounds *  whereToFind,
bool &  colinearity,
bool &  areOverlapped 
) [virtual]

Should be called once ! non const method.

Parameters:
whereToFind specifies the box where final seek should be done. Essentially it is used for caracteristic reason.
colinearity returns if regarding QUADRATIC_PLANAR::_precision ; e1 and e2 are colinears If true 'this' is modified ! So this method be called once above all if true is returned for this parameter.
areOverlapped if colinearity if true, this parameter looks if e1 and e2 are overlapped.

Implements INTERP_KERNEL::EdgeIntersector.
