Detailed Description

template<template< int, typename > class QF, int N, typename T = double>
class geom::ComplexWithFreeVertex< QF, N, T >

A local simplicial complex with a free node at the center.

Parameters:

	QF	is the quality functor for the simplices.
	N	is the dimension.
	T	is the number type. By default it is double.

This class implements the complex of simplices that surround a free node. It provides functions to aid in the optimization of the location of this node. The faces in the complex that are not incident to the free node are fixed. You can set the fixed faces with the ComplexWithFreeVertex(FaceIterator begin,FaceIterator end) constructor or with set(FaceIterator begin,FaceIterator end). You can evaluate various quantities as a function of the position of the free node:

• computeBBox(const Vertex& v,BBox<N,T>* bb) calculates the bounding box for the complex.
• computeContent(const Vertex& v) returns the content of the complex.
• computeGradientOfContent(const Vertex& v,Vertex* gradient) calculates the gradient of the content.
• computeNorm2(const Vertex& v) returns the 2-norm of the quality metric.
• computeGradientOfNorm2(const Vertex& v,Vertex* gradient) calculates the gradient of the 2-norm of the quality metric.
• computeNorm2Modified(const Vertex& v) returns the 2-norm of the modified quality metric.
• computeGradientOfNorm2Modified(const Vertex& v,Vertex* gradient) calculates the gradient of the 2-norm of the modified quality metric.
