<DIV><SPAN class=229565113-06092002><FONT face=Arial>What I did in the
Java-Program is to simple store the function currently displayed in the edior in
an array. When the vtk window has to be redrawn and the transfer function has
been modified, I just create a new vtkColorTransferFunction from the array.
Although this is of course not optimal, the overhead introduced is negligible,
if node counts don't get to high. How many nodes do you expect to be in
your functions?</FONT></DIV>

<BLOCKQUOTE style="MARGIN-RIGHT: 0px">I have got a question concerning the
package you have mentioned. I'm using vtkqt by Matthias Koenig which works
fine except for the fact that I'm not able to render stereo in his
vtkQtRenderWindow. Calling the method "StereoCapableOn()" results in an error.
Could you please test for me if this method works with the package you are
using ?<BR><BR>A week ago I downloaded your java-program to graphically edit a
transfer function. I'm trying to<BR>implement something similar using Qt.
Unfortunately, I encountered a problem concerning the<BR>editing of a
vtkColorTransferFunction. You can add a point to this function and you
can remove<BR>one but I couldn't find a method to modify an already existing
point. However, this is necessary<BR>for my application because I want to
enable the user to change the transfer function interactively.<BR>The problem
is that I don't want a new point to be added each time the user changes the
color<BR>but I want to modify the recently added point. How did you manage
this ?<BR><BR>Regards,<BR>Steffen<BR><BR>Stefan Bruckner wrote:<BR>
