◆ intersection() [1/2]

template<class Geometry1 , class Geometry2 , class Policy >
template<class P = Policy, std::enable_if_t< P::dimIntersection==3, int > = 0>
static bool Dumux::GeometryIntersection< Geometry1, Geometry2, Policy, 3, 3, 3 >::intersection ( const Geometry1 &  geo1,
const Geometry2 &  geo2,
Intersection intersection 
)
inlinestatic

Colliding two convex polyhedra.

Note
First we find the vertex candidates for the intersection region as follows: Add vertices that are inside the other geometry for both geometries Add all intersection points of edges (codim 2) with the other tetrahedron's faces triangle Remove duplicate points from the list Return a triangulation of the polyhedron formed by the convex hull of the point cloud
Parameters
geo1/geo2The geometries to intersect
intersectionContainer to store the corner points of the polygon (as convex hull)
Note
This overload is used when polyhedron-like intersections are seeked

◆ intersection() [2/2]

template<class Geometry1 , class Geometry2 , class Policy >
template<class P = Policy, std::enable_if_t< P::dimIntersection !=3, int > = 0>
static bool Dumux::GeometryIntersection< Geometry1, Geometry2, Policy, 3, 3, 3 >::intersection ( const Geometry1 &  geo1,
const Geometry2 &  geo2,
Intersection intersection 
)
inlinestatic

Colliding segment and convex polyhedron.

Parameters
geo1/geo2The geometries to intersect
intersectionContainer to store the intersection result
Todo:
implement overloads for polygon-, segment- or point-like intersections
