﻿NurbsSurfacePointList Methods

# NurbsSurfacePointList Methods

The NurbsSurfacePointList type exposes the following members.

Methods
NameDescription
EnsurePrivateCopy
If you want to keep a copy of this class around by holding onto it in a variable after a command completes, call EnsurePrivateCopy to make sure that this class is not tied to the document. You can call this function as many times as you want.
EpsilonEquals
Check that all values in other are within epsilon of the values in this
Equals (Inherited from Object.)
GetControlPoint
Gets the control point at the given (u, v) index.
GetGrevillePoint
Gets the 2-D Greville point associated with the control point at the given (u, v) index.
GetHashCode (Inherited from Object.)
GetPoint(Int32, Int32, Point3d)
Gets a world 3-D, or Euclidean, control point at the given (u, v) index. The 4-D representation is (x, y, z, 1.0).
GetPoint(Int32, Int32, Point4d)
Gets a homogeneous control point at the given (u, v) index, where the 4-D representation is (x, y, z, w). The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).
GetType (Inherited from Object.)
GetWeight
Gets the weight of a control point at the given (u, v) index. Note, if the surface is non-rational, the weight will be 1.0.
SetControlPoint(Int32, Int32, ControlPoint)
Sets the control point at the given (u, v) index.
SetControlPoint(Int32, Int32, Point3d)
Sets the control point at the given (u, v) index.
SetPoint(Int32, Int32, Point3d)
Sets a world 3-D, or Euclidean, control point at the given (u, v) index. The 4-D representation is (x, y, z, 1.0).
SetPoint(Int32, Int32, Point4d)
Sets a homogeneous control point at the given (u, v) index, where the 4-D representation is (x, y, z, w). The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).
SetPoint(Int32, Int32, Point3d, Double)
Sets a world 3-D, or Euclidean, control point and weight at a given index. The 4-D representation is (x*w, y*w, z*w, w).
SetPoint(Int32, Int32, Double, Double, Double)
Sets a world 3-D, or Euclidean, control point at the given (u, v) index. The 4-D representation is (x, y, z, 1.0).
SetPoint(Int32, Int32, Double, Double, Double, Double)
Sets a homogeneous control point at the given (u, v) index, where the 4-D representation is (x, y, z, w). The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).
SetWeight
Sets the weight of a control point at the given (u, v) index. Note, if the surface is non-rational, it will be converted to rational.
ToString (Inherited from Object.)
ValidateSpacing
Simple check of distance between adjacent control points
