.SH NAME
SoPendulum \- 
.PP
The \fBSoPendulum\fP class is used to create oscillating rotations\&.
.PP
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\&.

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\&.

.PP
Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for run-time type checking and 'downward' casting\&. Usage example:
.PP
.PP
.nf
void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}
.fi

.PP
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in \fIall\fP 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 \fBInventor/nodes/SoSubNode\&.h\fP (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine\&.h (for engine classes) and so on\&.

.PP
Reimplemented from \fBSoRotation\fP\&.
.SS "const \fBSoFieldData\fP * SoPendulum::getFieldData (void) const\fC [protected]\fP, \fC [virtual]\fP"
Returns a pointer to the class-wide field data storage object for this instance\&. If no fields are present, returns \fCNULL\fP\&. 
.PP
Reimplemented from \fBSoRotation\fP\&.
.SS "void SoPendulum::write (\fBSoWriteAction\fP *action)\fC [virtual]\fP"
Action method for \fBSoWriteAction\fP\&.
.PP
Writes out a node object, and any connected nodes, engines etc, if necessary\&.

.SS "\fBSoSFRotation\fP SoPendulum::rotation1"
The other rotation limit of the interpolation\&. 
.SS "\fBSoSFFloat\fP SoPendulum::speed"
Speed in cycles per second\&. Defaults to 1\&. 
.SS "\fBSoSFBool\fP SoPendulum::on"
