Method Details

getIndex

public int getIndex()

Get an index indicating the segment's position along a path.

Returns:

the index

getStart

public Point3D getStart()

Get the starting point for the segment

Returns:

the starting point for the segment

getEnd

public Point3D getEnd()

Get the ending point for the segment.

Returns:

the ending point

getSegmentLength

public double getSegmentLength()

Get the length of a segment.

Returns:

the length of the segment

getSegmentLengthFunction

public RealValuedFunctOps getSegmentLengthFunction()

Get a function that will compute the length of a subsegment from the start of of the segment to a point specified by the segment's path parameter.

In some unusual cases, a function is not available due to numerical accuracy issues, in which case numerical integration may be used.

Returns:

a function that computes the subsegment length given a path parameter provided as the function's argument; null if a function is not available.

getCoords

public double[] getCoords()

Get the coordinate array for the segment. This will include intermediate control points the end point

Returns:

the coordinate array for the segment

getData

public Path3DInfo.SegmentData getData()

Get the segment data associated with this segment.

Returns:

the segment data for this entry

getType

public int getType()

Get the type of the segment

Returns:

the segment type (PathIterator3D.SEG_MOVETO, PathIterator3D.SEG_LINETO, PathIterator3D.SEG_QUADTO, PathIterator3D.SEG_CUBICTO and PathIterator3D.SEG_CLOSE)

getTypeString

public String getTypeString()

Get the type of the segment, formatted as a string

Returns:

a string describing the segment type
