These splines give the user more control over the shape of the curve than the cardinal splines implemented in vtkCardinalSpline . Three parameters can be specified. All have a range from -1 to 1.
Tension controls how sharply the curve bends at an input point.
A value of -1 produces more slack in the curve. A value of 1 tightens the curve. Continuity controls the continuity of the first derivative at input points. Bias controls the direction of the curve at it passes through an input point. A value of -1 undershoots the point while a value of 1 overshoots the point.
