GeoTouchSensor
A GeoTouchSensor node tracks the location and state of a pointing device and detects when the user points at geometry contained by the parent group of the GeoTouchSensor. This node provides the same functionality as a TouchSensor but also provides the ability to return the geographic coordinate under the pointing device.

Filter: X3D only | Avalon only | All
id | Name | DataType | PartType | Default | ValueType | Description |
---|---|---|---|---|---|---|
geoOrigin | SFNode | initializeOnly | GeoOrigin | used to specify a local coordinate frame for extended precision | ||
geoSystem | MFString | initializeOnly | 'GD','WE' | used to define the spatial reference frame | ||
hitGeoCoord_changed | SFVec3d | outputOnly | (-inf, inf) | generated while the pointing device is pointing towards the GeoTouchSensor's geometry (i.e., when isOver is TRUE). It is a field containing the geospatial coordinate for the point of intersection between the pointing device's location and the underlying geometry. The value of the geoSystem string defines the spatial reference frame of the geospatial coordinate. | ||
hitNormal_changed | SFVec3f | outputOnly | Events containing surface normal vector at the hitPoint. | |||
hitPoint_changed | SFVec3f | outputOnly | Events containing 3D point on surface of underlying geometry, given in TouchSensor's local coordinate system. | |||
hitTexCoord_changed | SFVec2f | outputOnly | Events containing texture coordinates of surface at the hitPoint. | |||
touchTime | SFTime | outputOnly | Time event generated when sensor is touched by pointing device. | |||
isOver | SFBool | outputOnly | Is pointing device over sensor's geometry? | |||
description | SFString | inputOutput | Text description to comment the sensor task. Can be used in run-time systems to give usefull feedback to the user and developer | |||
enabled | SFBool | inputOutput | TRUE | Enables/disables the sensor node. | ||
isActive | SFBool | outputOnly | FALSE | isActive true/false events are sent when the sensor gets active | ||
metadata | SFNode | inputOutput | MetadataObject | container for payload metadata inside MetadataSet element |
