Detailed Description

Interpolates supplied nodes with bezier line segments.

The line interpolator interpolates supplied nodes (see InterpolateLine) with bezier line segments. The finess of the curve may be controlled using SetMaximumCurveError and SetMaximumNumberOfLineSegments.

Subclasses that wish to interpolate a line segment must implement this. For instance vtkBezierContourLineInterpolator adds nodes between idx1 and idx2, that allow the contour to adhere to a bezier curve.

Implements vtkContourLineInterpolator.

virtual void vtkBezierContourLineInterpolator::SetMaximumCurveError ( double )

virtual

The difference between a line segment connecting two points and the curve connecting the same points. In the limit of the length of the curve dx -> 0, the two values will be the same. The smaller this number, the finer the bezier curve will be interpolated. Default is 0.005

virtual double vtkBezierContourLineInterpolator::GetMaximumCurveError ( )

virtual

The difference between a line segment connecting two points and the curve connecting the same points. In the limit of the length of the curve dx -> 0, the two values will be the same. The smaller this number, the finer the bezier curve will be interpolated. Default is 0.005

virtual void vtkBezierContourLineInterpolator::SetMaximumCurveLineSegments ( int )

virtual

Maximum number of bezier line segments between two nodes. Larger values create a finer interpolation. Default is 100.

virtual int vtkBezierContourLineInterpolator::GetMaximumCurveLineSegments ( )

virtual

Maximum number of bezier line segments between two nodes. Larger values create a finer interpolation. Default is 100.

virtual void vtkBezierContourLineInterpolator::GetSpan	(	int	nodeIndex,
		vtkIntArray *	nodeIndices,
		vtkContourRepresentation *	rep
	)

virtual

Span of the interpolator. ie. the number of control points its supposed to interpolate given a node. The first argument is the current nodeIndex. ie, you'd be trying to interpolate between nodes "nodeIndex" and "nodeIndex-1", unless you're closing the contour in which case, you're trying to interpolate "nodeIndex" and "Node=0". The node span is returned in a vtkIntArray. The node span is returned in a vtkIntArray. The node span returned by this interpolator will be a 2-tuple with a span of 4.
