id Name DataType PartType Default ValueType Description
MFDouble uKnot MFDouble initializeOnly Knot vector, where size = number of control points + order of curve.
MFDouble vKnot MFDouble initializeOnly Knot vector, where size = number of control points + order of curve.
MFDouble weight MFDouble inputOutput Vector assigning weight to each control point.
MFNode trimmingContour MFNode inputOutput Contour2D The trimmingContour field, if specified, shall contain a set of Contour2D nodes.
SFBool solid SFBool initializeOnly TRUE Setting solid true means draw only one side of polygons (backface culling on), setting solid false means draw both sides of polygons (backface culling off). Warning: default value true can completely hide geometry if viewed from wrong side!
SFBool uClosed SFBool initializeOnly FALSE Whether opposite surface sides are closed (seamless) across u dimension.
SFBool vClosed SFBool initializeOnly FALSE Whether opposite surface sides are closed (seamless) across u dimension.
SFInt32 uDimension SFInt32 initializeOnly 0 Number of control points in u dimension.
SFInt32 uOrder SFInt32 inputOutput 3 Define order of surface by polynomials of degree = order-1.
SFInt32 uTessellation SFInt32 inputOutput 1 hint for surface tesselation.
SFInt32 vDimension SFInt32 initializeOnly 0 Number of control points in v dimension.
SFInt32 vOrder SFInt32 initializeOnly 3 Define order of surface by polynomials of degree = order-1.
SFInt32 vTessellation SFInt32 inputOutput 1 hint for surface tesselation.
SFNode addTrimmingContour SFNode inputOnly Contour2D add Trimming Contour field
SFNode controlPoint SFNode inputOutput Coordinate controlPoint defines a set of control points of dimension uDimension x vDimension. This set of points defines a mesh where the points do not have a uniform spacing.
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
SFNode removeTrimmingContour SFNode inputOnly Contour2D remove Trimming Contour field
SFNode texCoord SFNode inputOutput VisualProperty texCoord provides additional information on how to generate texture coordinates. By default, texture coordinates are generated automatically from the parametric subdivision.
