.PP 
The \fBSoComposeRotation\fP class is used to compose rotations from angle and axis\&.
.PP
Simple usage example: 


.PP
.nf
#Inventor V2\&.1 ascii

Separator {
   Transform {
      rotation =
      ComposeRotation { axis 0 1 0  angle =
         ElapsedTime { }\&.timeOut
      }\&.rotation
   }
   Cube { }
}

.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
For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups\&. 
.PP
Implements \fBSoBase\fP\&.
.SS "const \fBSoFieldData\fP * SoComposeRotation::getFieldData (void) const\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 \fBSoFieldContainer\fP\&.
.SS "const \fBSoEngineOutputData\fP * SoComposeRotation::getOutputData (void) const\fC [virtual]\fP"
\fIThis API member is considered internal to the library, as it is not likely to be of interest to the application programmer\&.\fP 
.PP
Implements \fBSoEngine\fP\&.
.SH "Member Data Documentation"
.PP 
.SS "\fBSoMFVec3f\fP SoComposeRotation::axis"
Set of axis vectors for the output rotations\&. Default value is (0\&.0f, 0\&.0f, 1\&.0f)\&. 
.SS "\fBSoMFFloat\fP SoComposeRotation::angle"
Set of scalar rotation values for the output rotations\&. Default value is 0\&.0\&. 
.SS "\fBSoEngineOutput\fP SoComposeRotation::rotation"
(\fBSoMFRotation\fP) Rotations generated from the angle and axis input fields\&.
