See Dragging Sensors for more information on this type of sensors. This node allows you to limit the draggin operation to a rectangular area. In addition to the fields which are common to all dragging sensors, this node has the following fields: maxPosition which specifies the maximum X and Y. minPosition which specifies the minimum X and Y. Note: if maxPosition is lower than minPosition for an axis, then the movement is not limited for that axis. By default the movement is not limited in neither X or Y. Syntax: PlaneSensor { enabled TRUE offset 0 0 0 autoOffset TRUE maxPosition -1 -1 minPosition 0 0 } In addition to the exposed fields presented in the syntax the CylinderSensor node generates the following events (see Dragging Sensors for a description of their meaning): isActive (boolean) translation_changed (3D vector) trackPoint_changed (3D point) Example: Using a PlaneSensor to move a Sphere in a rectangular area defined by (-1,-1), (1,1). First one needs to create a group node which will include both the sensor and a Transform node containg a Sphere geometry. Example: #VRML V2.0 utf8 Group { children [ DEF ts PlaneSensor { minPosition -1 -1 maxPosition 1 1 } DEF tr Transform { children Shape {geometry Cylinder {}} } ] } Now we need to create a route between the eventOut translation_changed from the PlaneSensor to the exposed field translation of the Transform node. The route to achieve this is: ROUTE ts.translation_changed TO tr.set_translation Note: On the VRML example provided the axes are not inside the same group as the sensor.
