NurbsPositionInterpolator

NurbsPositionInterpolator describes a 3D NURBS Curve and outputs interpolated position values. The SFNode controlPoint field can contain a single Coordinate or CoordinateDouble node.

id Name DataType PartType Default ValueType Description
SFFloat set_fraction SFFloat inputOnly setting fraction in range [0,1] selects input key for corresponding keyValue output, computing a 3D position on the curve.
SFVec3f value_changed SFVec3f outputOnly Linearly interpolated output value determined by current key time and corresponding keyValue pair.
MFDouble knot MFDouble inputOutput knot vector, where size = number of control points + order of curve.
SFInt32 order SFInt32 inputOutput 3 define order of surface by polynomials of degree = order-1.
MFDouble weight MFDouble inputOutput Output values for linear interopolation, each corresponding to knots. Hint: number of weights must match number of knots!
SFNode controlPoint SFNode inputOutput Coordinate Uses same definition as NurbsCurve
SFBool enabled SFBool inputOutput TRUE Flag to enable/disable the node behaviour
MFString logFeature MFString inputOutput state, child, parent, route, eventIn, eventOut controls the logging of changes, state: log state changes (e.g. live), child: log child add/remove, parent: log parent add/remove, route: log route add/remove; eventIn: log receiving of events, eventOut: log sending of events: guiView, runtime system should create node-view, guiEdit: runtime system should create node-editeverything: log everything
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
