<DIV><FONT face=Arial size=2>Dear all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am trying to get a vtkFollower to track a
particular object on screen i.e. I would like the X,Y,Z coordinates of the
follower to move with a particular mesh on screen, but the orientation to stay
fixed ( facing the screen). </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I setup an assembly with a mesh (representing a
tool) and two followers, that should track the extremities of the tool. On first
display everything looks alright. However, as soon as I SetCamera() in each
Follower, all relative information between them and the tool seems to be lost.
The difference in position along the depth of the tool is converted into
difference in position with respect to the screen i.e. once the camera is
set, the position between the two followers never changes, while there should be
relative movement between them as the two followers are placed at different
depths.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is this a bug, or is this the way vtkFollower is
intended to work? And if the latter is the case, does anyone know of an easy way
to accomplish what I am trying to do?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any help would be much appreciated.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks!</FONT></DIV>
