Function Documentation

template<typename MeshT >

double MeshFunctions::calc_angle_around	(	const MeshT &	_mesh,
		const typename MeshT::VertexHandle	_vh
	)

Get the sum of the angles around a vertex

Parameters

_mesh	Mesh to work on
_vh	Vertex

Returns: Sum of angles around the vertex

Definition at line 216 of file MeshFunctions.cc.

template<typename MeshT >

double MeshFunctions::calc_area ( const MeshT & _mesh )

Get the area of a mesh ( sum over all triangle areas)

Parameters

_mesh Mesh to calculate area

Returns: Area spanned by the mesh
