Package esys :: Package pyvisi :: Module normals :: Class Normals

Class Normals

Known Subclasses:

ellipsoid.Ellipsoid
, ellipsoid.EllipsoidOnPlaneClip
, ellipsoid.EllipsoidOnPlaneCut

Class that defines normals. Normals are used to average the normals of points in order to generate better sufaces (in the case of tensors, normals avoids the tensors from appearing black in color).

Instance Methods

__setInput(self)

vtkPolyData

_getNormalsOutput(self)
Return the output of the normals.

_setupNormals(self, object)
Setup the normals.
