Reimplemented in \fBSoPendulum\fP, and \fBSoRotor\fP\&.

This function performs the typical operation of a node for any action\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoRotation::GLRender (\fBSoGLRenderAction\fP * action)\fR [virtual]\fP"
Action method for the \fBSoGLRenderAction\fP\&.

.PP
This is called during rendering traversals\&. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoRotation::callback (\fBSoCallbackAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoCallbackAction\fP\&.

.PP
Simply updates the state according to how the node behaves for the render action, so the application programmer can use the \fBSoCallbackAction\fP for extracting information about the scene graph\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoRotation::getBoundingBox (\fBSoGetBoundingBoxAction\fP * action)\fR [virtual]\fP"
Action method for the \fBSoGetBoundingBoxAction\fP\&.

.PP
Calculates bounding box and center coordinates for node and modifies the values of the \fIaction\fP to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node\&.

.PP
Nodes influencing how geometry nodes calculate their bounding box also override this method to change the relevant state variables\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoRotation::getMatrix (\fBSoGetMatrixAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoGetMatrixAction\fP\&.

Updates \fIaction\fP by accumulating with the transformation matrix of this node (if any)\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoRotation::pick (\fBSoPickAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoPickAction\fP\&.

Does common processing for \fBSoPickAction\fP \fIaction\fP instances\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoRotation::getPrimitiveCount (\fBSoGetPrimitiveCountAction\fP * action)\fR [virtual]\fP"
Action method for the \fBSoGetPrimitiveCountAction\fP\&.

.PP
Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the \fIaction\fP\&.

.PP
Nodes influencing how geometry nodes calculate their primitive count also override this method to change the relevant state variables\&. 
.PP
Reimplemented from \fBSoNode\fP\&.

.PP 
.SS "\fBSoSFRotation\fP SoRotation::rotation"
Rotation specification\&. Defaults to no rotation at all\&. See the \fBSbRotation\fP documentation for instructions on how to set the value of this field\&.

.PP
Note that there is one \fIvery\fP common mistake that is easy to make when setting the value of an \fBSoSFRotation\fP field, and that is to inadvertently use the wrong \fBSbRotation\fP constructor\&. This example should clarify the problem:

.PP
.PP
.nf
mytransformnode\->rotation\&.setValue(0, 0, 1, 1\&.5707963f);
.fi
.PP

.PP
The programmer clearly tries to set a PI/2 rotation around the Z-axis, but this will fail, as the \fBSbRotation\fP constructor invoked above is the one that takes as arguments the 4 floats of a \fIquaternion\fP\&. What the programmer almost certainly wanted to do was to use the \fBSbRotation\fP constructor that takes a rotation vector and a rotation angle, which is invoked like this:

Another common problem is to set the rotation value to exactly 0\&.0, while wanting to store just a rotation \fIangle\fP in the field: rotations are internally handled as quaternions, and when converting from an angle and a rotation value to a quaternion representation, the information about the angle 'gets lost' if there is no actual rotation\&.
