ControlPoint

ControlPoint struct

Represents control point geometry with three-dimensional position and weight.

Derived Classes:

Namespace: Rhino.Geometry
ControlPoint: references

Constructors (5)

ControlPoint(double x, double y, double z, double weight)

Constructs a new homogeneous control point, where the 4-D representation is (x, y, z, w). The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).

ControlPoint(double x, double y, double z)

Constructs a new world 3-D, or Euclidean, control point. The 4-D representation is (x, y, z, 1.0).

ControlPoint(Point3d euclideanPt, double weight)

Constructs a control point from a world 3-D, or Euclidean, location and a weight. The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).

ControlPoint(Point3d pt)

Constructs a new world 3-D, or Euclidean, control point. The 4-D representation of this is (x, y, z, 1.0).

ControlPoint(Point4d pt)

Constructs a new homogeneous control point, where the 4-D representation is (x, y, z, w). The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).

Properties (6)

Location

Gets or sets world 3-D, or Euclidean location of the control point.

Unset

Gets the predefined, unset control point.

Weight

Gets or sets the weight of this control point.

X

Gets or sets the X coordinate of the control point.

Y

Gets or sets the Y coordinate of the control point.

Z

Gets or sets the Z coordinate of the control point.

Methods (2)

EpsilonEquals(ControlPoint other, double epsilon)

Check that all values in other are within epsilon of the values in this

Equals(ControlPoint other)

Determines if two points exactly match.
