SphericalHarmonics

The SphericalHarmonics node is a geometry node for visualizing the famous SH functions y. It is to be used within a Shape node and can have an Appearance. Hint: this type of geometry already has vertex colors; green if y is positive and red if not.

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
SFBool lit SFBool initializeOnly TRUE Specifies whether to enable/disable lighting the geometry. TRUE enables lighting, FALSE disables lighting.
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
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 useGeoCache SFBool initializeOnly TRUE controlls the use of geometry caches for primitives with equal properties
SFInt32 bandIndex SFInt32 inputOutput 0 The band index l (must not be negative).
SFString channel SFString inputOutput r [r, g, b] If SH coefficients are given, the channel defines, which component of the SH coefficient vector shall be used for display.
MFVec3f coefficients MFVec3f inputOutput SH coefficients (of size bandIndex x bandIndex). If given, the node generates the geometry according to the coefficients instead for a single (l,m) parameterization.
SFInt32 functionIndex SFInt32 inputOutput 0 The function index m, with m in [-l,l].
SFBool invalidateVolume SFBool inputOutput FALSE set volume invalid
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
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 resolution SFFloat inputOutput 1 factor for subdivision of mesh
SFInt32 subdivision SFInt32 inputOutput 100 Specifies the number of samples for subdividing the node for rendering.
