Constructor & Destructor Documentation

◆ Rectangle()

Rectangle ( const Point< real_t > &  bbm,
const Point< real_t > &  bbM,
int  code = 1 
)

Constructor.

Parameters
[in]bbmLeft Bottom point of rectangle
[in]bbMRight Top point of rectangle
[in]codeCode to assign to rectangle

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]gGrid instance
[in]dVect 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]pPoint 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]pPoint<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]bbmLeft Bottom point
[in]bbMRight Top point
