Hi!<div><br></div><div><div>I'm using vtkPolyDataNormals to obtain point normals on my mesh. The idea is to use these normals to compute curvatures using polynomial fitting.</div></div><div><br></div><div>The problem is that vtkPolyDataNormals is not giving me the correct normal orientations for all vertices. Here's an example image:</div>
<div><br></div><div><a href="http://tinypic.com/r/2dv7l36/7">http://tinypic.com/r/2dv7l36/7</a></div><div><br></div><div>as you can see, for now I'm using a synthetic, perfectly regular noiseless mesh!</div><div><br></div>
<div>Here's my code for computing normals:</div><div><div><br></div><div>vtkSmartPointer<vtkPolyDataNormals> normals = vtkSmartPointer<vtkPolyDataNormals>::New();</div><div>normals->SetInput( meshdata->polydata );</div>
<div>normals->SplittingOff();</div><div>normals->ComputePointNormalsOn();</div><div>normals->ComputeCellNormalsOff();</div><div>normals->Update();</div></div><div><br></div><div>Thanks,</div><div>Miguel</div>
