vtkPolyDataNormals 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.
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).
|
What is the input update extent that is required to produce the desired output? By default, the whole input is always required but this is overridden in many subclasses. Reimplemented from vtkPolyDataSource. |
|
Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataToPolyDataFilter. |
|
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataToPolyDataFilter. |
|
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataToPolyDataFilter. |
|
Construct with feature angle=30, splitting and consistency turned on, flipNormals turned off, and non-manifold traversal turned on. ComputePointNormals is on and ComputeCellNormals is off. Reimplemented from vtkPolyDataSource. |
|
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkSource. |
|
Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataToPolyDataFilter. |
|
Turn on/off the computation of Cell Normals. |
|
Turn on/off the computation of Point Normals. |
|
Turn on/off the enforcement of consistent polygon ordering. |
|
Specify the angle that defines a sharp edge. If the difference in angle across neighboring polygons is greater than this value, the shared edge is considered "sharp". |
|
Turn on/off the global flipping of normal orientation. Flipping reverves the meaning of front and back for Frontface and Backface culling in vtkProperty. Flipping modifies both the normal direction and the order of a cell's points. |
|
Control the depth of recursion used in this algorithm. (Some systems have limited stack depth.) |
|
Turn on/off traversal across non-manifold edges. This will prevent problems where the consistency of polygonal ordering is corrupted due to topological loops. |
|
Turn on/off the splitting of sharp edges. |
