DESCRIPTION¶

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

FIELDS¶

SoSFRotation rotation0
SoSFRotation rotation1
These define the two fixed rotations that are interpolated to create the pendular motion.

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

SoSFBool on
Allows applications to enable or disable the motion easily.

METHODS¶

SoPendulum()
Creates a pendulum node with default settings.

static SoType getClassTypeId()
Returns type identifier for this class.

ACTION BEHAVIOR¶

SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoRayPickAction
Concatenates interpolated rotation value with the current transformation matrix.
SoGetMatrixAction
Returns transformation matrix specified by the interpolated rotation.
