When in doubt, use the default parameter value.

Parameters

type	the geometry type
c	a function returning the ith corner (in Dune reference element order) e.g. `[&](unsigned int i){ return corners[i]; }`, where `corners` is a random access container storing the corners, and the returned corner is stored in a container (e.g. Dune::FieldVector) that exports `value_type` and `dimension`.

Template Parameters

dim	the dimension of the geometry
CornerF	the function type (is deduced)

Returns: volume of the geometry or NaN signalling not implemented

Note: This is only correct for convex polytopes (flat sides)

Triangulate area given points of a convex hull (2d)

Template Parameters

dim	Specifies the dimension of the resulting triangulation
dimWorld	The dimension of the coordinate space
Policy	Specifies the algorithm to be used for triangulation

Note: this specialization is for 1d discretization using segments; sorts the points and connects them via segments

Template Parameters

dim	Specifies the dimension of the resulting triangulation
dimWorld	The dimension of the coordinate space
Policy	Specifies the algorithm to be used for triangulation

Note: this specialization is for 2d triangulations using mid point policy; Assumes all points of the convex hull are coplanar; This inserts a mid point and connects all corners with that point to triangles; Assumes points are given as a ordered sequence representing the polyline forming the convex hull

Template Parameters

dim	Specifies the dimension of the resulting triangulation
dimWorld	The dimension of the coordinate space
Policy	Specifies the algorithm to be used for triangulation
