GeoProximitySensor
Overview
GeoProximitySensor generates events when the viewer enters, exits and moves within a region of space (defined by a box).
The GeoProximitySensor node belongs to the Geospatial component and requires at least support level 2, its default container field is children. It is available from X3D version 3.2 or higher.

Fields
SFNode [in, out] metadata NULL [X3DMetadataObject]
Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.
Hint
SFString [in, out] description “”
Author-provided prose that describes intended purpose of the node.
Hint
- Many XML tools substitute XML character references for special characters automatically if needed within an attribute value (such as & for & ampersand character, or " for “ quotation-mark character).
SFNode [ ] geoOrigin NULL [GeoOrigin] (deprecated)
Single contained GeoOrigin node that can specify a local coordinate frame for extended precision.
Hint
Warning
- XML validation requires placement as first child node following contained metadata nodes (if any).
MFString [ ] geoSystem [ “GD”, “WE” ]
Identifies spatial reference frame: Geodetic (GD), Geocentric (GC), Universal Transverse Mercator (UTM). Supported values: “GD” “UTM” or “GC” followed by additional quoted string parameters as appropriate for the type.
Hints
- X3D Architecture 25.2.2 Spatial reference frames
- X3D Architecture 25.2.4 Specifying geospatial coordinates
- UTM is Universal Transverse Mercator coordinate system
Warning
- Deprecated values are GDC (replaced by GD) and GCC (replaced by GC).
SFBool [in, out] enabled TRUE
Enables/disables node operation.
SFVec3f [in, out] size 0 0 0 [0,∞)
size of Proximity box around center location, oriented within local transformation frame.
Hint
- size 0 0 0 is same as enabled false.
SFVec3d [in, out] center 0 0 0 (-∞,∞) (starting with vs. 3.3)
Position offset from origin of local coordinate system.
SFVec3d [in, out] geoCenter 0 0 0 (-∞,∞)
Position offset from origin of local coordinate system.
Hint
Warning
- Requires X3D
profile='Full'
or else include<component name='Geospatial' level='1'/>
SFBool [out] isActive
isActive true/false events are sent as viewer enters/exits Proximity box. isActive=true when viewer enters Proximity box, isActive=false when viewer exits Proximity box.
Warning
- It is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
SFTime [out] enterTime
Time event generated when user’s camera enters the box.
Warning
- It is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
SFTime [out] exitTime
Time event generated when user’s camera exits the box.
Warning
- It is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
SFVec3d [out] geoCoord_changed
Sends geospatial coordinates of viewer’s position corresponding to world position returned by position_changed.
Hint
Warnings
- Requires X3D
profile='Full'
or else include<component name='Geospatial' level='1'/>
- It is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
SFVec3f [out] position_changed
Sends translation event relative to center.
Warning
- It is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
SFRotation [out] orientation_changed
Sends rotation event relative to center.
Warning
- It is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
SFVec3f [out] centerOfRotation_changed
Sends changed centerOfRotation values, likely caused by user interaction.
Warning
- It is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
Advice
Hints
- Multiple USEd instances are cumulative, but avoid overlaps.
- Can first use GeoTransform to relocate/reorient box.
- Surround entire world to start behaviors once scene is loaded.
- X3D for Advanced Modeling (X3D4AM) slideset
Warning
- Requires X3D
profile='Full'
or else include<component name='Geospatial' level='2'/>
