Detailed DescriptionThe 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​. FILE FORMAT/DEFAULTS: Pendulum { rotation 0 0 1 0 rotation0 0 0 1 0 rotation1 0 0 1 0 speed 1 on TRUE }

Member Function Documentation

SoType SoPendulum::getTypeId (void) const [virtual]Returns the type identification of an object derived from a class inheriting SoBase​. This is used for run-time type checking and 'downward' casting​. Usage example: void foo(SoNode * node) { if (node->getTypeId() == SoFile::getClassTypeId()) { SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type } }For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses​. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode​.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine​.h (for engine classes) and so on​. For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups​. Reimplemented from SoRotation​.

const SoFieldData * SoPendulum::getFieldData (void) const [protected], [virtual]Returns a pointer to the class-wide field data storage object for this instance​. If no fields are present, returns NULL​. 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​.
