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