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 |
---|---|---|---|---|---|---|
geoSystem | MFString | initializeOnly | 'GD','WE' | Defines the geographic coordinate system that will be used for the geospatial coordinates in that node. | ||
rootUrl | MFString | initializeOnly | Use rootUrl to specify root geometry. Hint: Use either rootNode or rootUrl, not both. | |||
child1Url | MFString | initializeOnly | Quadtree geometry loaded when viewer is within range. | |||
child2Url | MFString | initializeOnly | Quadtree geometry loaded when viewer is within range. | |||
child3Url | MFString | initializeOnly | Quadtree geometry loaded when viewer is within range. | |||
child4Url | MFString | initializeOnly | Quadtree geometry loaded when viewer is within range. | |||
center | SFVec3d | initializeOnly | 0 0 0 | Viewer range from geographic-coordinates center triggers quadtree loading/unloading. | ||
range | SFFloat | initializeOnly | 10 | [0, inf) | Viewer range from geographic-coordinates center triggers quadtree loading/unloading. | |
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. | |||
geoOrigin | SFNode | initializeOnly | GeoOrigin | The geoOrigin field is used to specify a local coordinate frame for extended precision. | ||
rootNode | SFNode | initializeOnly | Node | Use rootNode to specify root geometry. Hint: Use either rootNode or rootUrl, not both. | ||
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. | ||
children | MFNode | inputOutput | Node | field that contains a list of children nodes | ||
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 | |||
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 | |||
bboxCenter | SFVec3f | initializeOnly | 0 0 0 | Bounding box center: position offset from origin of local coordinate system. | ||
bboxSize | SFVec3f | initializeOnly | -1 -1 -1 | Bounding box size: automatically calculated, can be specified as an optimization or constraint. | ||
render | SFBool | inputOutput | TRUE | Flag to control the visibility of the node or subtree | ||
showBBox | SFBool | inputOutput | FALSE | Show Bounding Box of Subtree. | ||
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 | ||
metadata | SFNode | inputOutput | MetadataObject | container for payload metadata inside MetadataSet element |
