NurbsSurface class

NurbsSurface class

NurbsSurface is a surface represented by NURBS(Non-uniform rational basis spline), A NurbsSurface is defined by two NurbsDirectionNurbsSurface.u and NurbsSurface.v. The w component in control point is used as control point’s weight whatever the direction’s type is a CurveDimension.TWO_DIMENSIONAL or CurveDimension.THREE_DIMENSIONAL

Inheritance: NurbsSurfaceGeometryEntitySceneObjectA3DObject

The NurbsSurface type exposes the following members:

Constructors

ConstructorDescription
__init__(self)Initializes a new instance of the NurbsSurface class.
__init__(self, name)Initializes a new instance of the NurbsSurface class.
