Hi list,<br>
<br>
the scalars of the vtkPolyData, the output of vtkCurvatures, contain<br>
the values of the (selected type of) curvature, if I understand<br>
correctly. I am looking for the way to associate each curvature value to<br>
a specific region of the surface (vertex/triangle/edge). Could you point<br>
me in the right direction please?<br>
<br>
On a related note, is there a way to make vtkCurvature compute both<br>
curvatures (i.e. mean and Gaussian) at the same time, instead of just<br>
one of them?<br>
<br>
Thanks!<br></blockquote><div><br></div><div>I think you just need to</div><div><br></div><div>polydata->GetPointData()->SetActiveScalars("YourArrayName") </div><div><br></div><div>to color the points by an array ( and polydata->GetCellData()->SetActiveScalars("YourArrayName") if the array is the same length as (and attached to) the triangles instead of the points)</div>
