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.
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 ccw SFBool initializeOnly TRUE If ccw is TRUE, the normals shall follow the right hand rule. Also used for orientation of trajectory curve.
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.
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.
SFFloat resolution SFFloat inputOutput 1 factor for subdivision of mesh
SFInt32 multiResolutionLevel SFInt32 initializeOnly 1 resolution level in progressive mesh
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 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 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.
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. Note: 'simpleStatic' needs 'glu 1.3' and may not work correctly under Windows.
SFString normalUpdateMode SFString initializeOnly nice none; fast; nice force update of normals; nice update is with creaseAngle, fast is without
