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: NurbsSurface → Geometry → Entity → SceneObject → A3DObject

The NurbsSurface type exposes the following members:

Constructors
