DESCRIPTION

69       The SoPendulum class is derived from SoRotation, so it applies a  rota‐
70       tion  to  the  current  transformation.  Using engines connected to the
71       realTime global field, the rotation value is animated over time between
72       two  fixed  rotations, achieving the effect of a swinging pendulum. The
73       period of the swing can be adjusted by changing the  speed  field.  The
74       current rotation at any time is available in the rotation field, inher‐
75       ited from SoRotation
76

FIELDS

78     SoSFRotation        rotation0
79     SoSFRotation        rotation1
80          These define the two fixed rotations that are interpolated to create
81          the pendular motion.
82
83     SoSFFloat           speed
84          Defines the speed of the pendulum, in cycles per second.
85
86     SoSFBool            on
87          Allows applications to enable or disable the motion easily.

METHODS

91                         SoPendulum()
92          Creates a pendulum node with default settings.
93
94     static SoType       getClassTypeId()
95          Returns type identifier for this class.

ACTION BEHAVIOR

99       SoGLRenderAction,  SoCallbackAction, SoGetBoundingBoxAction, SoRayPick‐
100       Action
101          Concatenates interpolated rotation value with the current  transfor‐
102          mation matrix.
103
104     SoGetMatrixAction
105          Returns  transformation  matrix  specified by the interpolated rota‐
106          tion.
