[vtkusers] Re: Best vtk / QT package?

[Stefan Bruckner]

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?

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 ?

A week ago I downloaded your java-program to graphically edit a transfer
function. I'm trying to
implement something similar using Qt. Unfortunately, I encountered a
problem concerning the
editing of a vtkColorTransferFunction. You  can add a point to this
function and you can remove
one but I couldn't find a method to modify an already existing point.
However, this is necessary
for my application because I want to enable the user to change the
transfer function interactively.
The problem is that I don't want a new point to be added each time the
user changes the color
but I want to modify the recently added point. How did you manage this ?

Regards,
Steffen

I've examined nearly all of the packages out there, most of them are
pretty outdated. The best and probably most current (VTK 4, QT 3) is
VTK_QT by Carsten Kuebler. 

Source is provided in an MS Visual Studio project, but I've managed to
compile it under Linux within minutes without problems.

I am trying to get vtk and qt working properly.

Which is the best vtk/qt package available?
Which has the best chance of being supported in the future?
Which should I avoid altogether? (maybe too old to work with newer
versions?)

I appreciate all help and opinions!

Thanks,
Alex Lear
