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¶

Detailed Description¶
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.

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.Member Data Documentation¶
SoSFRotation SoPendulum::rotation0¶
The first rotation limit of the interpolation.SoSFRotation SoPendulum::rotation1¶
The other rotation limit of the interpolation.SoSFFloat SoPendulum::speed¶
Speed in cycles per second. Defaults to 1.SoSFBool SoPendulum::on¶
Toggles animation on or off. Defaults to being on.Author¶
