Constructor Detail

DefaultArcString

public DefaultArcString(Points controlPoints)
Creates a new DefaultArcString instance from the given parameters.

Parameters:
controlPoints - interpolation points
Method Detail

getCoordinateDimension

public int getCoordinateDimension()
Description copied from interface: CurveSegment
Returns the coordinate dimension, i.e. the dimension of the space that the curve is embedded in.

Specified by:
getCoordinateDimension in interface CurveSegment
Returns:
the coordinate dimension

getControlPoints

public Points getControlPoints()
Description copied from interface: ArcString
Returns the control points of the interpolation.

The number of points is always 2 * k + 1 points (k >= 1).

Specified by:
getControlPoints in interface ArcString
Returns:
the control points of the interpolation, never null

getNumArcs

public int getNumArcs()
Description copied from interface: ArcString
Returns the number of arcs of the string.

Specified by:
getNumArcs in interface ArcString
Returns:
the number n of arcs (n >= 1)

getStartPoint

public Point getStartPoint()
Description copied from interface: CurveSegment
Returns the start point of the segment.

Specified by:
getStartPoint in interface CurveSegment
Returns:
the start point of the segment

getEndPoint

public Point getEndPoint()
Description copied from interface: CurveSegment
Returns the end point of the segment.

Specified by:
getEndPoint in interface CurveSegment
Returns:
the end point of the segment

getSegmentType

public CurveSegment.CurveSegmentType getSegmentType()
Description copied from interface: CurveSegment
Returns the type of curve segment.

Specified by:
getSegmentType in interface CurveSegment
Returns:
the type of curve segment
