SpotLight

SpotLight is a light source that illuminates geometry within a conical beam Light illuminates all geometry and is not scoped by scene graph hierarchy Lights have no visible shape themselves and shine through occluding geometry. Hint: HeadLight is controlled by NavigationInfo.

id Name DataType PartType Default ValueType Description
SFVec3f attenuation SFVec3f inputOutput 1 0 0 Constant, linear-distance and squared-distance dropoff factors.
SFFloat beamWidth SFFloat inputOutput 1.570796 (NOT IMPLEMENTED YET) Inner solid angle (in radians) where light source has uniform full intensity if beamWidth greater then; cutOffAngle, beamWidth reset to equal cutOffAngle.
SFFloat cutOffAngle SFFloat inputOutput 0.785398 Outer solid angle (in radians) where light source intensity becomes zero if beamWidth greater then; cutOffAngle, beamWidth reset to equal cutOffAngle.
SFVec3f direction SFVec3f inputOutput 0 0 -1 Orientation of light relative to local coordinate system.
SFVec3f location SFVec3f inputOutput 0 0 0 Position of light relative to local coordinate system.
SFFloat radius SFFloat inputOutput 100 (NOT IMPLEMENTED YET) Maximum effective distance of light relative to local light position, affected by ancestor scaling.
SFBool global SFBool inputOutput TRUE indicates if the light is global (influences all elements in the scene) or local (only the childs of the parent node)
SFFloat ambientIntensity SFFloat inputOutput 0 [0, 1] Brightness of ambient (nondirectional background) emission from the light.
SFColor color SFColor inputOutput 1 1 1 color of light, applied to colors of objects.
SFFloat intensity SFFloat inputOutput 1 [0, 1] Brightness of direct emission from the light.
SFBool showProxyGeometry SFBool inputOutput FALSE toggle geometry at light position (use for visual debugging)
SFVec3f proxyGeometrySize SFVec3f inputOutput 1 1 1 scales proxy geometry
SFFloat shadowIntensity SFFloat inputOutput 0 [0, 1] intensity of the shadow; 0 is no shadow at all
SFBool on SFBool inputOutput TRUE Enables/disables this effector (e.g. light)
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
