CGAL 5.1.2 - 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.

Operations | |

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.
