compute normals for polygonal mesh
<p>
<a class="el" href="a01267.html" title="compute normals for polygonal mesh">vtkPolyDataNormals</a> is a filter that computes point normals for a polygonal mesh. 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.<p>
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).<p>
<dl class="warning" compact><dt><b>Warning:</b></dt><dd>Normals are computed only for polygons and triangle strips. Normals are not computed for lines or vertices.<p>
Triangle strips are broken up into triangle polygons. You may want to restrip the triangles.</dd></dl>
