NurbsCurve

NurbsCurve is a 3D curve analogous to NurbsPatchSurface. The container controlPoint field is a Coordinate or CoordinateDouble node.

id Name DataType PartType Default ValueType Description
MFDouble knot MFDouble initializeOnly knot vector, where size = number of control points + order of curve.
MFDouble weight MFDouble inputOutput vector assigning weight to each control point.
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
MFString optimizationMode MFString inputOutput auto auto; all, none, sharedVertex; stripFan; vertexResort; reduceIndexSize; singleIndex optimization mode settings; used leading +/- to switch modes on and off
SFBool closed SFBool initializeOnly FALSE Whether or not the curve is closed (i.e. matching endpoints).
SFBool invalidateVolume SFBool inputOutput FALSE set volume invalid
SFBool lit SFBool initializeOnly TRUE Specifies whether to enable/disable lighting the geometry. TRUE enables lighting, FALSE disables lighting.
SFFloat resolution SFFloat inputOutput 1 factor for subdivision of mesh
SFInt32 multiResolutionLevel SFInt32 initializeOnly 1 resolution level in progressive mesh
SFInt32 order SFInt32 initializeOnly 3 define order of surface by polynomials of degree = order-1.
SFInt32 tessellation SFInt32 inputOutput 1 hint for surface tesselation.
SFNode controlPoint SFNode inputOutput Coordinate controlPoint defines a set of control points to describe the final shape of the surface.
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
SFString cacheMode SFString initializeOnly auto auto; dlist; vbo; off controls the creation of geo cache objects; auto is vbo or dlist for dynamic objects
SFString meshGenerationType SFString inputOutput auto auto; dynamic; simpleStatic; advancedStatic Geometry creation mode.
SFString normalUpdateMode SFString initializeOnly nice none; fast; nice force update of normals; nice update is with creaseAngle, fast is without
