Constructor Details

CircleShape

public CircleShape(double radius)

Constructor.

Parameters:

radius - radius.

CircleShape

public CircleShape(double radius,
 int polygonSegments)

Constructor.

Parameters:

radius - radius.

polygonSegments - number of segments in polygon representation.

Method Details

getRelativeBounds

public Bounds2d getRelativeBounds()

Description copied from interface: OtsShape

Returns the bounds relative to the location. The default implementation returns the bounds of the contour.

Specified by:

getRelativeBounds in interface Locatable

Specified by:

getRelativeBounds in interface OtsShape

Returns:

bounds relative to the location.

signedDistance

public double signedDistance(Point2d point)

Description copied from interface: OtsShape

Signed distance function. The point must be relative. 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, which is expensive.

Specified by:

signedDistance in interface OtsShape

Parameters:

point - point for which distance is returned.

Returns:

distance from point to these bounds.

getRelativeContour

public Polygon2d getRelativeContour()

Description copied from interface: OtsShape

Returns the contour of the object in relative coordinates.

Specified by:

getRelativeContour in interface OtsShape

Returns:

the contour of the object in relative coordinates

toString

public String toString()

Overrides:

toString in class Object
