id Name DataType PartType Default ValueType Description
SFBool closed SFBool initializeOnly FALSE Whether or not the curve is closed (i.e. matching endpoints).
MFDouble knot MFDouble initializeOnly knot vector, where size = number of control points + order of curve.
SFInt32 order SFInt32 initializeOnly 3 define order of surface by polynomials of degree = order-1.
MFVec2d controlPoint MFVec2d inputOutput The control points are defined in 2D coordinate space.
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
SFInt32 tessellation SFInt32 inputOutput 0 hint for surface tesselation.
MFDouble weight MFDouble inputOutput vector assigning weight to each control point.
