Constructor & Destructor Documentation

Rectangle()

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

Constructor.

Parameters

[in]	bbm	Left Bottom point of rectangle
[in]	bbM	Right Top point of rectangle
[in]	code	Code to assign to rectangle

Member Function Documentation

getSignedDistance()

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
