NurbsSweptSurface
NurbsSweptSurface describes a generalized surface that defines a path in 2D space and constant cross section that may be 2D or 3D. Conceptually it is the NURBS equivalent of the Extrusion node but permits the use of non-closed cross sections. It contains a crossSectionCurve [X3DNurbsControlCurveNode] and a trajectoryCurve [NurbsCurve]

| id | Name | DataType | PartType | Default | ValueType | Description |
|---|---|---|---|---|---|---|
 |
crossSectionCurve | SFNode | inputOutput | NurbsControlCurveNode | 2D or 3D curve for describing a constant cross section of the path | |
|
trajectoryCurve | SFNode | inputOutput | NurbsControlCurveNode | The trajectory curve is a 2d curve in the xz-plane that describes the path over which to trace the cross-section. | |
 |
ccw | SFBool | inputOutput | TRUE | ccw = counterclockwise: ordering of vertex coordinates orientation. Hint: ccw false can reverse solid (backface culling) and normal-vector orientation. | |
|
solid | SFBool | inputOutput | 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! | |
|
lit | SFBool | initializeOnly | TRUE | Specifies whether to enable/disable lighting the geometry. TRUE enables lighting, FALSE disables lighting. | |
 |
resolution | SFFloat | inputOutput | 1 | factor for subdivision of mesh | |
 |
multiResolutionLevel | SFInt32 | initializeOnly | 1 | resolution level in progressive mesh | |
|
invalidateVolume | SFBool | inputOutput | FALSE | set volume invalid | |
 |
normalUpdateMode | SFString | initializeOnly | nice | none; fast; nice | force update of normals; nice update is with creaseAngle, fast is without |
|
cacheMode | SFString | initializeOnly | auto | auto; dlist; vbo; off | controls the creation of geo cache objects; auto is vbo or dlist for dynamic objects |
 |
optimizationMode | MFString | inputOutput | auto | auto; all, none, sharedVertex; stripFan; vertexResort; reduceIndexSize; singleIndex | optimization mode settings; used leading +/- to switch modes on and off |
|
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 | |
|
metadata | SFNode | inputOutput | MetadataObject | container for payload metadata inside MetadataSet element |
