I think I will wait for the next release of activiz and hope that things will become better then.
<br/>
In between I will write my own filters by simply iterating over own vtkPolydata structures.
<br/>
I am very successfull with this although not getting the data processed in parallel.
<br/>
<br/>
Meanwhile I tried paraview and python custom filters which is OK for prototyping purposes.
<br/>
<br/>
Would be glad to stay in contact and get some news on this, if any...
<br/>
<br/>

I found a topic where someone was able to inherit successfully from a
<br/>
Activiz/vtk class.
<br/>
<br/>

<br/>
Note: All classes are static, that's the reason why you cannot inherit
<br/>
from any wrapped vtk class.
<br/>
But as I learned a few days ago there's a way to extent a static class.
<br/>
If you like I can show you how to do that.

<br/>
<br/>
And there is also an example how the guy managed it to do that. The
<br/>
example he wrote worked for me but I have tried it with another class
<br/>
and I get a InvalidCastException at the constructor.
<br/>
<br/>
public class myCommand : vtkCommand
<br/>
{
<br/>
private vtkPolyData Points;
<br/>
<br/>
public myCommand()
<br/>
{
<br/>
Points = vtkPolyData.New();
<br/>
}
<br/>
<br/>
//public override void Execute(vtkObject caller, uint eventId,
<br/>
IntPtr callData)
<br/>
//{
<br/>
// base.Execute(caller, eventId, callData);
<br/>
// Console.WriteLine("Callback!");
<br/>
//}
<br/>
}
<br/>
<br/>
I did not understand so far why this not work and the other example works.
