Filter: X3D only | Avalon only | All
| 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. | ||
| vKnot | MFDouble | initializeOnly | Knot vector, where size = number of control points + order of curve. | |||
| vOrder | SFInt32 | initializeOnly | 3 | Define order of surface by polynomials of degree = order-1. | ||
| 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 | ||
| meshGenerationType | SFString | inputOutput | auto | auto; dynamic; simpleStatic; advancedStatic | Geometry creation mode. Note: 'simpleStatic' needs 'glu 1.3' and may not work correctly under Windows. | |
| metadata | SFNode | inputOutput | MetadataObject | container for payload metadata inside MetadataSet element | ||
| optimizationMode | MFString | inputOutput | auto | auto; all, none, sharedVertex; stripFan; vertexResort; reduceIndexSize; singleIndex | optimization mode settings; used leading +/- to switch modes on and off | |
| resolution | SFFloat | inputOutput | 1 | factor for subdivision of mesh | ||
| 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. | ||
| uOrder | SFInt32 | inputOutput | 3 | Define order of surface by polynomials of degree = order-1. | ||
| uTessellation | SFInt32 | inputOutput | 1 | hint for surface tesselation. | ||
| vTessellation | SFInt32 | inputOutput | 1 | hint for surface tesselation. | ||
| weight | MFDouble | inputOutput | Vector assigning weight to each control point. |
