Do_intersect_3

typedef unspecified_type IntersectionGeometricTraits_3::Do_intersect_3

Function object that detects an intersection between a 3D segment and a 3D triangle.

Partial model of Kernel::DoIntersect_3. Provides the operators:

• bool operator()(Segment_3 seg, Triangle_3 tr)
• bool operator()(Triangle_3 tr, Segment_3 seg)

which returns true, iff the triangle and the segment have a non empty intersection.

Intersect_3

typedef unspecified_type IntersectionGeometricTraits_3::Intersect_3

Function object that constructs the intersection between a 3D segment and a 3D triangle.

Partial model of Kernel::Intersect_3. Provides the operators:

• std::optional< std::variant< Point_3, Segment_3 > > operator()(Segment_3 seg, Triangle_3 tr)
• std::optional< std::variant< Point_3, Segment_3 > > operator()(Triangle_3 tr, Segment_3 seg)

which computes the intersection between the triangle and the segment.
