Detailed Description

To store and treat a figure (or shape) information.

This class is essentially useful to construct data for mesh generators and for distance calculations.

Member Function Documentation

Compute signed distance from a line.

Parameters

[in]	p	Point for which distance is computed
[in]	a	First vertex of line
[in]	b	Second vertex of line

void getSignedDistance	(	const Grid &	g,
		Vect< real_t > &	d ) const

Calculate signed distance to current figure with respect to grid points.

Parameters

[in]	g	Grid instance
[in]	d	Vect instance containing calculated distance from each grid index to Figure

virtual real_t getSignedDistance ( const Point< real_t > & p ) const

virtual

Return signed distance from a given point to current figure.

Parameters

[in] p Point instance from which distance is computed
