Member Function Documentation

intersection() [1/3]

template<class Geometry1, class Geometry2, class Policy>

template<class P = Policy, std::enable_if_t< P::dimIntersection==0, int > = 0>

bool Dumux::GeometryIntersection< Geometry1, Geometry2, Policy, 3, 2, 2 >::intersection ( const Geometry1 & geo1, const Geometry2 & geo2, Intersection & intersection )

inlinestatic

Parameters

geo1/geo2	The geometries to intersect
intersection	The intersection point

Note

this overload is used when point-like intersections are seeked

intersection() [2/3]

template<class Geometry1, class Geometry2, class Policy>

template<class P = Policy, std::enable_if_t< P::dimIntersection==1, int > = 0>

bool Dumux::GeometryIntersection< Geometry1, Geometry2, Policy, 3, 2, 2 >::intersection ( const Geometry1 & geo1, const Geometry2 & geo2, Intersection & intersection )

inlinestatic

Parameters

geo1/geo2	The geometries to intersect
intersection	Container to store the corners of intersection segment

Note

this overload is used when segment-like intersections are seeked

intersection() [3/3]

template<class Geometry1, class Geometry2, class Policy>

template<class P = Policy, std::enable_if_t< P::dimIntersection==2, int > = 0>

bool Dumux::GeometryIntersection< Geometry1, Geometry2, Policy, 3, 2, 2 >::intersection ( const Geometry1 & geo1, const Geometry2 & geo2, Intersection & intersection )

inlinestatic

Note

First we find the vertex candidates for the intersection region as follows: Add vertices of first polygon that are inside the second polygon Add intersections of polygon edges Remove duplicate points from the list Compute the convex hull polygon

Parameters

geo1/geo2	The geometries to intersect
intersection	Container to store the corner points of the polygon (as convex hull)

Note

This overload is used when polygon like intersections are seeked
