Hi Simon, 

unfortunately that is what tried (before I used the method I told you before) - but without any success. My code is as follows:

InitVTKSendor{

matrix = vtkMatrix4x4::New();

actor = vtkActor::New();

actor->SetUserMatrix(matrix);

ren1->AddActor(actor)

renWin->Render();

}

 

UpdataVTKSensor{

actor->GetUserMatrix()->SetElement(i,j,z); ....

actor->GetUserMatrix()->Modified();

renWin->Render()

}

The first Render() produces a nice image. The Update-procedure results in no change whatever I use as matrix->SetElement() inputs.

 

Regards, Peter.
