See Dragging Sensors for more information on this type of sensors. This node allows you to limit the draggin operation between two angles. The offset field is relative to the X axis. In addition to the fields which are common to all dragging sensors, this node has the following fields: maxAngle which specifies the maximum rotation. minAngle which specifies the minimum rotation. diskAngle: I still haven't found how this field affects the behaviour of the node Note: if maxAngle is smaller than minAngle, then the rotation is not limited.. By default the rotation is not limited. Syntax: PlaneSensor { enabled TRUE offset 0 autoOffset TRUE maxAngle -1 minAngle 0 diskAngle 0.262 } 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) rotation_changed (3D vector plus an angle, the 3D vector is the Y axis of the local coordinate system) trackPoint_changed (3D point) The following example uses a CylinderSensor to rotate a Cone limited between 0 and 1.57 (+- 90 degrees). First one needs to create a group node which will include both the sensor and a Transform node containg a Cone geometry. Example: #VRML V2.0 utf8 Group { children [ DEF cs CylinderSensor { minAngle 0 maxAngle 1.57 } DEF tr Transform { children Shape {geometry Cylinder {}} } ] } Now we need to create a route between the eventOut rotation_changed from the CylinderSensor to the exposed field rotation of the Transform node. The route to achieve this is: ROUTE cs.rotation_changed TO tr.set_rotation Note: On the VRML example provided the axes are not inside the same group as the sensor.
