NAME
SoPendulum -The SoPendulum class is used to create oscillating rotations.
A smooth transition between rotation0 and rotation1 is created using a cosine function. In the beginning of the cycle, rotation0 is used. Halfway through the cycle, the resulting rotation equals rotation1, and at the end of the cycle, we're at rotation0 again.
SYNOPSIS
#include <Inventor/nodes/SoPendulum.h>
Inherits SoRotation.

Member Function Documentation
void SoPendulum::initClass (void) [static]Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
Reimplemented from SoRotation.
void SoPendulum::write (SoWriteAction * action) [virtual]Action method for SoWriteAction.
Writes out a node object, and any connected nodes, engines etc, if necessary.
Reimplemented from SoNode.
