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

Constructor	Description
init	Initializes a new instance of the NurbsSurface class.
init	Initializes a new instance of the NurbsSurface class.

Properties

Property	Description
name	Gets or sets the name.
properties	Gets the collection of all properties.
scene	Gets the scene that this object belongs to
parent_nodes	Gets all parent nodes, an entity can be attached to multiple parent nodes for geometry instancing
excluded	Gets or sets whether to exclude this entity during exporting.
parent_node	Gets or sets the first parent node, if set the first parent node, this entity will be detached from other parent nodes.
visible	Gets or sets if the geometry is visible
deformers	Gets all deformers associated with this geometry.
control_points	Gets all control points
cast_shadows	Gets or sets whether this geometry can cast shadow
receive_shadows	Gets or sets whether this geometry can receive shadow.
vertex_elements	Gets all vertex elements
u	Gets the NURBS surface’s U direction
v	Gets the NURBS surface’s V direction
