[vtkusers] Rotation of single axis

[Robert V Canning]

Hi,

I am using VTK 5.0.2 with Tcl 8.4.13 on a Windows XP system.  I am still
fairly new at both VTK and Tcl and I have inherited a program requiring
some changes.  I have used the Azimuth and Elevation procedure to move the
view of the scene.  I have a 3D plot with multiple objects (actors) in it
along with X,Y,Z axis lines.  I would like to be able to rotate a single
axis for instance the X while keeping the camera fixed.  Do I need to
rotate each object or is there a way to move the whole group?  Are there
any examples (Tcl) out there that show this.  For instance if the camera is
moved so that the X,Y,Z axis appear tilted, I would then like to be able to
rotate the X axis only so that the object would look as if it is spinning.

Thank you,

Bob
