CylinderSensor Node


The CylinderSensor node maps the mouse movement into the a conceptual cylinder, rotating the shapes in the Y axis of its local coordinate system. 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.
