Class Patch

Patch class

A Patch is a parametric modeling surface, similar to NurbsSurface, it’s also defined by two PatchDirection, the U and V. But difference between Patch and NurbsSurface is that the PatchDirection curve can be one of Bezier, QuadraticBezier, BasisSpline, CardinalSpline and Linear

public class Patch : Geometry

Constructors

NameDescription
Patch()Initializes a new instance of the Patch class.
Patch(string)Initializes a new instance of the Patch class.

Properties

NameDescription
CastShadows { get; set; }Gets or sets whether this geometry can cast shadow
ControlPoints { get; }Gets all control points
Deformers { get; }Gets all deformers associated with this geometry.
Excluded { get; set; }Gets or sets whether to exclude this entity during exporting.
virtual Name { get; set; }Gets or sets the name.
ParentNode { get; set; }Gets or sets the first parent node, if set the first parent node, this entity will be detached from other parent nodes.
