<p>Hello,<br>
<br>
instead of using the "->setRadius(double)" option, i would like to subClass the vtkSphereSource in such a way that it is possible to pass a pointer (double*) to it.<br>
The goal is to simply assign a pointer once and the sphere should automatically change its radius when the double value, which the pointer is pointing to, changes.<br>
I just want to call the "->update()" option of the Qt widget but avoid changing the radius manually.<br>
<br>
Is this possible? Any ideas how to subclass the vtkSource?<br>
<br>
Best Regards<br>
