Plane Constructor (Point3d, Point3d, Point3d)

Initializes a plane from three non-collinear points.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 5.0
public Plane(
	Point3d origin,
	Point3d xPoint,
	Point3d yPoint


Type: Rhino.GeometryPoint3d
Origin point of the plane.
Type: Rhino.GeometryPoint3d
Second point in the plane. The x-axis will be parallel to x_point-origin.
Type: Rhino.GeometryPoint3d
Third point on the plane that is not collinear with the first two points. taxis*(y_point-origin) will be > 0.
