Member Function Documentation

void setBoundingBox	(	const Point< double > &	bbm,
		const Point< double > &	bbM
	)

Assign bounding box of the brick.

Parameters:

[in]	bbm	first point (xmin,ymin,zmin)
[in]	bbM	second point (xmax,ymax,zmax)

double getSignedDistance

(

const Point< double > &

p

)

const [virtual]

Return signed distance of a given point from the current brick.

The computed distance is negative if p lies in the brick, negative if it is outside, and 0 on its boundary

Parameters:

[in]

p

Point<double> instance

Reimplemented from Figure.

Brick& operator+=

(

Point< double >

a

)

Operator +=.

Translate brick by a vector a

Brick& operator+=

(

double

a

)

Operator *=.

Scale brick by a factor a

void getSignedDistance	(	const Grid &	g,
		Vect< double > &	d
	)		const [inherited]

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 [inherited]

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
