X3D Reference

GeoLOD

GeoLOD

GeoLOD provides quadtree level-of-detail loading/unloading for multi-resolution terrains. GeoLOD can contain children and GeoOrigin nodes.

The GeoLOD node belongs to the Geospatial component and its container field is children. It is available since X3D version 3.0 or later.

Hierarchy

* Derived from multiple interfaces.

Fields

SFNode [in, out] metadata NULL [X3DMetadataObject]

Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.

SFNode [ ] geoOrigin NULL [GeoOrigin] (deprecated)

Field geoOrigin.

MFString [ ] rootUrl [ ] [URI]

Use either rootNode or rootUrl to specify root geometry, not both.

MFString [ ] child1Url [ ] [URI]

Quadtree geometry loaded when viewer is within range.

MFString [ ] child2Url [ ] [URI]

Quadtree geometry loaded when viewer is within range.

MFString [ ] child3Url [ ] [URI]

Quadtree geometry loaded when viewer is within range.

MFString [ ] child4Url [ ] [URI]

Quadtree geometry loaded when viewer is within range.

SFVec3d [ ] center 0 0 0 (-∞,∞)

Viewer range from geographic-coordinates center triggers quadtree loading/unloading.

SFFloat [ ] range 10 [0,∞)

Viewer range from geographic-coordinates center triggers quadtree loading/unloading.

Hint

Not setting range values indicates that level switching can be optimized automatically based on performance.

SFInt32 [out] level_changed

Output field level_changed.

MFNode [ ] rootNode [ ] [X3DChildNode]

Field rootNode.

SFVec3f [ ] bboxSize -1 -1 -1 [0,∞) or −1 −1 −1

Bounding box size is usually omitted, and can easily be calculated automatically by an X3D player at scene-loading time with minimal computational cost. Bounding box size can also be defined as an optional authoring hint that suggests an optimization or constraint.

Hint

Can be useful for collision computations or inverse-kinematics (IK) engines.

SFVec3f [ ] bboxCenter 0 0 0 (-∞,∞)

Bounding box center: optional hint for position offset from origin of local coordinate system.

MFNode [out] children

Output field children.

Description

Hints

  • Children nodes expose the scene graph for the currently loaded set of nodes.
  • RootNode specifies the geometry of the root tile.
  • Include <component name='Geospatial' level='1'/>

Warning

  • Do not use rootUrl and rootNode simultaneously, since each specifies the root tile.
