[vtkusers] update unstructured grid

[John Platt]

Hi Naim,

 

Have you tried pUnstructuredGrid->Update() before setting the scalars?

Hi vtkUsers,  

 

I need help how to update an unstructured grid?

I change the scalars and I call "update" and/or "modified" functions,
but the results are wrong.

 

I create pScalars (vtkDoubleArray)

pUnstructuredGrid->GetPointData()->SetScalars(pScalars);

.

I show the plot. The plot is fine.

   

I change the scalars like this:

for(long i = 0; i < Size; ++i)

{             

        aNodeValue = pPlotData[i];  // new scalars data             

        pScalars->SetValue(i, aNodeValue);                      

}   

pScalars->Update(); // or pScalars->Modified();

pUnstructuredGrid->GetPointData()->SetScalars(pScalars);

 

.

I show the plot but the results are not correct.

 

 

Please any idea.
