Constructor Details

BoundingBoxRounded

public BoundingBoxRounded(double dx,
 double dy,
 double r)

Constructor.

Parameters:

dx - double; complete length along x dimension.

dy - double; complete length along y dimension.

r - double; radius of rounding, must be positive.

Method Details

getMinX

public double getMinX()

Specified by:

getMinX in interface org.djutils.draw.bounds.Bounds<OtsBounds2d,org.djutils.draw.point.Point2d,org.djutils.draw.Drawable2d>

Specified by:

getMinX in interface OtsBounds2d

getMaxX

public double getMaxX()

Specified by:

getMaxX in interface org.djutils.draw.bounds.Bounds<OtsBounds2d,org.djutils.draw.point.Point2d,org.djutils.draw.Drawable2d>

Specified by:

getMaxX in interface OtsBounds2d

getMinY

public double getMinY()

Specified by:

getMinY in interface org.djutils.draw.bounds.Bounds<OtsBounds2d,org.djutils.draw.point.Point2d,org.djutils.draw.Drawable2d>

Specified by:

getMinY in interface OtsBounds2d

getMaxY

public double getMaxY()

Specified by:

getMaxY in interface org.djutils.draw.bounds.Bounds<OtsBounds2d,org.djutils.draw.point.Point2d,org.djutils.draw.Drawable2d>

Specified by:

getMaxY in interface OtsBounds2d

contains

public boolean contains(org.djutils.draw.point.Point2d point)
                 throws NullPointerException

Specified by:

contains in interface org.djutils.draw.bounds.Bounds<OtsBounds2d,org.djutils.draw.point.Point2d,org.djutils.draw.Drawable2d>

Specified by:

contains in interface OtsBounds2d

Throws:

NullPointerException

covers

public boolean covers(org.djutils.draw.point.Point2d point)
               throws NullPointerException

Specified by:

covers in interface org.djutils.draw.bounds.Bounds<OtsBounds2d,org.djutils.draw.point.Point2d,org.djutils.draw.Drawable2d>

Specified by:

covers in interface OtsBounds2d

Throws:

NullPointerException

signedDistance

public double signedDistance(org.djutils.draw.point.Point2d point)

Signed distance function. The coordinates must be transformed to this bound's space. Negative distances returned are inside the bounds, with the absolute value of the distance towards the edge. The default implementation is based on the polygon representation and is expensive.

Specified by:

signedDistance in interface OtsBounds2d

Parameters:

point - Point2d; point for which distance is returned.

Returns:

double; distance from point to these bounds.

asPolygon

public org.djutils.draw.line.Polygon2d asPolygon()

Returns a polygon representation of the bounds, such that an intersection can be derived.

Specified by:

asPolygon in interface OtsBounds2d

Returns:

Polygon2d; polygon representation of the bounds.
