SoPendulum¶

InventorModule¶

genre	`InventorNodesAutomatic`
author	`Silicon Graphics Inc`
package	`MeVisLab/Standard`
definition	inventor.def

Purpose¶

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.
