Detailed Description

compute normals for polygonal mesh

vtkPolyDataNormals is a filter that computes point and/or cell normals for a polygonal mesh. The user specifies if they would like the point and/or cell normals to be computed by setting the ComputeCellNormals and ComputePointNormals flags.

The computed normals (a vtkFloatArray) are set to be the active normals (using SetNormals()) of the PointData and/or the CellData (respectively) of the output PolyData. The name of these arrays is "Normals", so they can be retrieved either with vtkFloatArray::SafeDownCast(output->GetPointData()->GetNormals()) or with vtkFloatArray::SafeDownCast(output->GetPointData()->GetArray("Normals"))

The filter can reorder polygons to insure consistent orientation across polygon neighbors. Sharp edges can be split and points duplicated with separate normals to give crisp (rendered) surface definition. It is also possible to globally flip the normal orientation.

The algorithm works by determining normals for each polygon and then averaging them at shared points. When sharp edges are present, the edges are split and new points generated to prevent blurry edges (due to Gouraud shading).

Warning: Normals are computed only for polygons and triangle strips. Normals are not computed for lines or vertices.; Triangle strips are broken up into triangle polygons. You may want to restrip the triangles.

Turn on/off the automatic determination of correct normal orientation. NOTE: This assumes a completely closed surface (i.e. no boundary edges) and no non-manifold edges. If these constraints do not hold, all bets are off. This option adds some computational complexity, and is useful if you don't want to have to inspect the rendered image to determine whether to turn on the FlipNormals flag. However, this flag can work with the FlipNormals flag, and if both are set, all the normals in the output will point "inward".
