<DIV><FONT face="Comic Sans MS" size=2></FONT> </DIV>
<DIV><FONT face="Comic Sans MS" size=2>I have searched the web for the solution
to this problem, but I have had no luck so far. I was able to display an axes
with arrow heads and axis labels using vtkAxes, vtkTubeFilter, vtkConeSource and
vtkFollower. The axes rotate with the 3D image accordingly, and the axis labels
always face the camera. Unfortunately, I have to statically set the vtkAxes
origin, and therefore, the axes disappear from the viewport when zooming. Does
anyone know a solution to always have the axes origin fixed to the lower left
corner of the viewport, but still correctly rotate with the image? I would
appreciate very much for any suggestion where to look for more
information and what functions to use and where in the codes to call them.
Thanks a lot in advance for your help.</FONT></DIV>
