Arc2D

Arc2D is a geometry node. Arc2D specifies a linear circular arc with center (0,0) with angles measured starting at positive x-axis and sweeping towards positive y-axis. Hint: insert a Shape node before adding geometry or Appearance.

Interface

Filter: X3D only | Avalon only | All
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
SFFloat endAngle SFFloat initializeOnly 1.570796 [0..2pi] Arc extends from startAngle counterclockwise to endAngle, in radians. Warning: simple-geometry dimensions cannot be changed after initial creation, use Transform scale instead.
SFBool invalidateVolume SFBool inputOutput FALSE set volume invalid
SFBool lit SFBool initializeOnly FALSE 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
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
SFFloat radius SFFloat initializeOnly 1 [0..infinity] radius of circle, of which the arc is a portion. Warning: simple-geometry dimensions cannot be changed after initial creation, use Transform scale instead.
SFFloat resolution SFFloat inputOutput 1 factor for subdivision of mesh
SFFloat startAngle SFFloat initializeOnly 0 [0..2pi] Arc extends from startAngle counterclockwise to endAngle, in radians. Warning: simple-geometry dimensions cannot be changed after initial creation, use Transform scale instead.
