Reimplemented from vtkCell . Reimplemented from vtkCell . Reimplemented from vtkObject . Create a local s-t coordinate system for a polygon. The values l20 and l20 are the lengths of the vectors p10 and p20, and n is the polygon normal.
Function uses ray-casting to determine if point is inside polygon.
Can also return -1 to indicate degenerate polygon. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkCell . The user must provide the vtkIdList outTris. On output, the outTris list contains the ids of the points defining the triangulation.
