[vtkusers] Useless triangulation in unstructured grid rendering

[Jacques Charreyron-F264897]

Dear vtkUsers,

I have noticed that when in an ugrid point values are are modified with
grid->GetPointData()->SetScalars(pointScalars) a triangulation is done in
vtkDataSetSurfaceFilter. Which is, I guess, useless and very time consuming. I
understand that glList of vertex has to be reconstruct to set new colors but
triangulation result should be taken directly from the filter.

Does anyone know why this triangulation is done ?

Yours,

Jacques Charreyron
