id | Name | DataType | PartType | Default | ValueType | Description |
---|---|---|---|---|---|---|
![]() |
cacheMode | SFString | initializeOnly | auto | auto; dlist; vbo; off | controls the creation of geo cache objects; auto is vbo or dlist for dynamic objects |
![]() |
ccw | SFBool | initializeOnly | TRUE | If ccw is TRUE, the normals shall follow the right hand rule. Also used for orientation of trajectory curve. | |
![]() |
lit | SFBool | initializeOnly | TRUE | Specifies whether to enable/disable lighting the geometry. TRUE enables lighting, FALSE disables lighting. | |
![]() |
multiResolutionLevel | SFInt32 | initializeOnly | 1 | resolution level in progressive mesh | |
![]() |
normalUpdateMode | SFString | initializeOnly | nice | none; fast; nice | force update of normals; nice update is with creaseAngle, fast is without |
![]() |
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! | |
![]() |
uClosed | SFBool | initializeOnly | FALSE | Whether opposite surface sides are closed (seamless) across u dimension. | |
![]() |
uDimension | SFInt32 | initializeOnly | 0 | Number of control points in u dimension. | |
![]() |
uKnot | MFDouble | initializeOnly | Knot vector, where size = number of control points + order of curve. | ||
![]() |
vClosed | SFBool | initializeOnly | FALSE | Whether opposite surface sides are closed (seamless) across u dimension. | |
![]() |
vDimension | SFInt32 | initializeOnly | 0 | Number of control points in v dimension. | |

![]() |
removeTrimmingContour | SFNode | inputOnly | Contour2D | remove Trimming Contour field | |
![]() |
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. | |
![]() |
invalidateVolume | SFBool | inputOutput | FALSE | set volume invalid | |
![]() |
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 | |
