CGAL 4.12  3D Mesh Generation

The concept IntersectionGeometricTraits_3
provides types and functors required to implement a model of MeshDomain_3
, when the domain is described by a simplicial surface mesh forming its boundary. The concept IntersectionGeometricTraits_3
mainly provides the detection and construction of intersections between segments and triangles.

Types  
typedef unspecified_type  Point_3 
Point type.  
typedef unspecified_type  Segment_3 
Segment type.  
typedef unspecified_type  Triangle_3 
Triangle type.  
typedef unspecified_type  Do_intersect_3

Operations  
Do_intersect_3  do_intersect_3_object () 
Returns the intersection detection functor.  
Intersect_3  intersect_3_object () 
Returns the intersection constructor.  
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.
Function object that constructs the intersection between a 3D segment and a 3D triangle.
Partial model of Kernel::Intersect_3
. Provides the operators:
boost::optional< boost::variant< Point_3, Segment_3 > > operator()(Segment_3 seg, Triangle_3 tr)
boost::optional< boost::variant< Point_3, Segment_3 > > operator()(Triangle_3 tr, Segment_3 seg)
which computes the intersection between the triangle and the segment.
