GeoLOD

GeoLOD provides quadtree level-of-detail loading/unloading for multi-resolution terrains. GeoLOD can contain children and GeoOrigin nodes. Hint: children nodes expose the scene graph for the currently loaded set of nodes. Hint: rootNode specifies the geometry of the root tile. Warning: do not use rootUrl and rootNode simultaneously, since each specifies the root tile.

Interface

Filter: X3D only | Avalon only | All
id Name DataType PartType Default ValueType Description
SFVec3f bboxCenter SFVec3f initializeOnly 0 0 0 Bounding box center: position offset from origin of local coordinate system.
SFVec3f bboxSize SFVec3f initializeOnly -1 -1 -1 Bounding box size: automatically calculated, can be specified as an optimization or constraint.
SFVec3d center SFVec3d initializeOnly 0 0 0 Viewer range from geographic-coordinates center triggers quadtree loading/unloading.
MFString child1Url MFString initializeOnly Quadtree geometry loaded when viewer is within range.
MFString child2Url MFString initializeOnly Quadtree geometry loaded when viewer is within range.
MFString child3Url MFString initializeOnly Quadtree geometry loaded when viewer is within range.
MFString child4Url MFString initializeOnly Quadtree geometry loaded when viewer is within range.
SFNode geoOrigin SFNode initializeOnly GeoOrigin The geoOrigin field is used to specify a local coordinate frame for extended precision.
MFString geoSystem MFString initializeOnly 'GD','WE' Defines the geographic coordinate system that will be used for the geospatial coordinates in that node.
SFFloat range SFFloat initializeOnly 10 [0, inf) Viewer range from geographic-coordinates center triggers quadtree loading/unloading.
SFNode rootNode SFNode initializeOnly Node Use rootNode to specify root geometry. Hint: Use either rootNode or rootUrl, not both.
MFString rootUrl MFString initializeOnly Use rootUrl to specify root geometry. Hint: Use either rootNode or rootUrl, not both.
SFString triggerName SFString initializeOnly Synchronize name of the dynamic context-slot which is used by the run-time environment (e.g. Jobs) to trigger the node. Life-Nodes will automatically connect the context-eventOutut to the triggerSlot-eventInput Slot.
MFNode addChildren MFNode inputOnly The addChildren event appends nodes to the children field of a grouping node. Any nodes passed to the addChildren inputOnly field that are already in the children list of the grouping node are ignored
MFNode removeChildren MFNode inputOnly The removeChildren event removes nodes from the children fieldof the grouping node . Any nodes in the removeChildren event that are not in the children list of the grouping node are ignored
MFNode children MFNode inputOutput Node field that contains a list of children nodes
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
SFBool render SFBool inputOutput TRUE Flag to control the visibility of the node or subtree
SFBool showBBox SFBool inputOutput FALSE Show Bounding Box of Subtree.
SFInt32 level_changed SFInt32 outputOnly event with value 0 or 1, where 0 indicates the rootNode field and 1 indicates the nodes specified by the child1Url, child2Url, child3Url, and child4Url fields.
