NAME

SoRotor -

The SoRotor class is a node used to animate rotations.

Insert this node in your hierarchy to apply a continuous rotation to some geometry. Since this node inherits the SoRotation node, rotation is restricted around the axis specified in the rotation field.

Detailed Description

The SoRotor class is a node used to animate rotations.

Insert this node in your hierarchy to apply a continuous rotation to some geometry. Since this node inherits the SoRotation node, rotation is restricted around the axis specified in the rotation field.

The angle value of the SoRotation::rotation field (inherited by this node) gives the rotation direction. If the value is larger than 0.0, the rotation will be done in the counterclockwise direction, if it is negative the rotation will be done in the clockwise direction.

Do not set the rotation value to exactly 0.0, as rotations are internally handled as quaternions, and when converting from an angle and a rotation value to a quaternion representation, the information about the angle 'gets lost' if there is no actual rotation.

Note also that the rotation will start at the given angle value.

FILE FORMAT/DEFAULTS:

     Rotor {
         rotation 0 0 1  0
         speed 1
         on TRUE
     }
