If the input surface is open in the direction specified by the "direction" attribute, then this node will make the surface periodic in that direction. If the input surface is periodic, then this node will make the surface open.

This node behaves as a toggle, ie. if a surface is closed twice, then the result is exactly the same as the original surface.

Use this node if you want to close a surface such that it becomes curvature continous along one direction.

Long name (short name)TypeDefaultFlags
inputSurface (is) nurbsSurfaceNULLoutputinputconnectable
The input surface
preserveShape (ps) enum1outputinputconnectablestorablekeyable
0 - without preserving the shape 1 - preserve shape 2 - blend
blendBias (bb) double0.5outputinputconnectablestorablekeyable
Skew the result toward the first or the second surface depending on the blend value being smaller or larger than 0.5.
blendKnotInsertion (bki) boolfalseoutputinputconnectablestorablekeyable
If set to true, insert a knot in one of the original surfaces (relative position given by the parameter attribute below) in order to produce a slightly different effect.
parameter (p) double0.1outputinputconnectablestorablekeyable
The parameter value for the positioning of the newly inserted knot.
direction (d) enum0outputinputconnectablestorablekeyable
The direction in which to close: 0 - U, 1 - V, 2 - Both U and V
