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.

Filter: X3D only | Avalon only | All
id Name DataType PartType Default ValueType Description
MFString geoSystem MFString initializeOnly 'GD','WE' Defines the geographic coordinate system that will be used for the geospatial coordinates in that node.
MFString rootUrl MFString initializeOnly Use rootUrl to specify root geometry. Hint: Use either rootNode or rootUrl, not both.
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.
SFVec3d center SFVec3d initializeOnly 0 0 0 Viewer range from geographic-coordinates center triggers quadtree loading/unloading.
SFFloat range SFFloat initializeOnly 10 [0, inf) Viewer range from geographic-coordinates center triggers quadtree loading/unloading.
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.
SFNode geoOrigin SFNode initializeOnly GeoOrigin The geoOrigin field is used to specify a local coordinate frame for extended precision.
SFNode rootNode SFNode initializeOnly Node Use rootNode to specify root geometry. Hint: Use either rootNode or rootUrl, not both.
MFNode children MFNode inputOutput Node field that contains a list of children nodes
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
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.
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
