Member Function Documentation

getSignedDistance() [1/3]

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

Remarks

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

getSignedDistance() [2/3]

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

Reimplemented from Figure.

getSignedDistance() [3/3]

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

virtual

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

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

Parameters

[in]

p

Point<double> instance

Reimplemented from Figure.

operator+=() [1/2]

Rectangle & operator+=

(

Point< real_t >

a

)

Operator +=.

Translate rectangle by a vector a

operator+=() [2/2]

Rectangle & operator+=

(

real_t

a

)

Operator *=.

Scale rectangle by a factor a

setBoundingBox()

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

Assign bounding box of the rectangle.

Parameters

[in]	bbm	Left Bottom point
[in]	bbM	Right Top point
