Introduction

vtkSpline3D provides methods for creating a 1D cubic spline object from given parameters, and allows for the calculation of the spline value and derivative at any given point inside the spline intervals.

Methods

computeCoefficients

Argument	Type	Required	Description
points		Yes

extend

Method used to decorate a given object (publicAPI+model) with vtkSpline3D characteristics.

Argument	Type	Required	Description
publicAPI		Yes	object on which methods will be bounds (public)
model		Yes	object on which data structure will be bounds (protected)
initialValues	ISpline3DInitialValues	No	(default: {})

getClose

Get whether the spline is closed (the last point is joined to the first).

getIntervals

Get the parametric values delimiting each spline interval. When empty, the intervals default to the point indices.

getPoint

Argument	Type	Required	Description
intervalIndex	Number	Yes
t	Number	Yes

newInstance

Method used to create a new instance of vtkSpline3D.

Argument	Type	Required	Description
initialValues	ISpline3DInitialValues	No	for pre-setting some of its content

setClose

Set whether the spline is closed (the last point is joined to the first).

Argument	Type	Required	Description
close	Boolean	Yes

setIntervals

Set the parametric values delimiting each spline interval. Pass an empty array to fall back to the point indices.

Argument	Type	Required	Description
intervals	Array[Number]	Yes
