Detailed Description

Animated oscillating rotation node.

The SoPendulum class is derived from SoRotation, so it applies a rotation to the current transformation. Using engines connected to the realTime global field, the rotation value is animated over time between two fixed rotations, achieving the effect of a swinging pendulum. The period of the swing can be adjusted by changing the speed field. The current rotation at any time is available in the rotation field, inherited from SoRotation

FILE FORMAT/DEFAULT

Pendulum {

rotation	0 0 1 0
rotation0	0 0 1 0
rotation1	0 0 1 0
speed	1
on	TRUE

}

ACTION BEHAVIOR

SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoRayPickAction
Concatenates interpolated rotation value with the current transformation matrix.

SoGetMatrixAction
Returns transformation matrix specified by the interpolated rotation.

SoSFRotation SoPendulum::rotation0

Defines the first of the two fixed rotations that are interpolated to create the pendular motion.

Defines the second of the two fixed rotations that are interpolated to create the pendular motion.

SoSFFloat SoPendulum::speed

Defines the speed of the pendulum, in cycles per second.
