[vtkusers] change the coordinates of some vertices.

Hi chen,

 

>From what I understand, your output polydata as the modified points but not
the cells

Try doing this:

 

outputPolyData->SetPolys( InputPolyData->GetPolys( ) );

it should work for most polygonal cells (as opposed to edge cells, point
cells, strip cells, .) Even Better, you do not copy, you just pass the
pointer to the cell array and thus should not increase memory consumption.

 

if it does not work, send me your code.

 

Alex.

Dear All:

 

    How could I only change coordinates of some points on mesh surface, and
keep the topology of polypdata?

 

   I created a new polydata, in which I only changed the coordinates of some
points. I can visualize the polydata, but can not generate the mesh surface
on the new polydata.

 

  Any advice on this?

 

Best Wishes,
