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.

virtual double getSignedDistance

(

const Point< double > &

p

)

const [virtual]

Return signed distance from a given point to current figure.

Parameters:

[in]

p

Point instance from which distance is computed

Reimplemented in Polygon, Triangle, Ellipse, Sphere, Circle, Brick, and Rectangle.

void getSignedDistance	(	const Grid &	g,
		Vect< double > &	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

Remarks:

Vector d doesn't need to be sized before invoking this function

double dLine	(	const Point< double > &	p,
		const Point< double > &	a,
		const Point< double > &	b
	)		const

Compute 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

Returns:

Signed distance
