public:
 static System::Windows::Media::Media3D::Vector3D Subtract(System::Windows::Media::Media3D::Point3D point1, System::Windows::Media::Media3D::Point3D point2);

public static System.Windows.Media.Media3D.Vector3D Subtract (System.Windows.Media.Media3D.Point3D point1, System.Windows.Media.Media3D.Point3D point2);

static member Subtract : System.Windows.Media.Media3D.Point3D * System.Windows.Media.Media3D.Point3D -> System.Windows.Media.Media3D.Vector3D

Public Shared Function Subtract (point1 As Point3D, point2 As Point3D) As Vector3D

Parameters

point1

Point3D

The Point3D structure to be subtracted from.

point2

Point3D

The Point3D structure to subtract from point1.

Returns

Vector3D

A Vector3D structure that represents the difference between point1 and point2.

Examples

The following example shows how to subtract a Point3D structure from a Point3D structure.

// Subtracts a Point3D from a Point3D using the static Subtract method.  
// Returns a Vector3D.

Point3D point1 = new Point3D(10, 5, 1);
Point3D point2 = new Point3D(15, 40, 60);
Vector3D vectorResult = new Vector3D();

vectorResult = Point3D.Subtract(point1, point2);
// vectorResult is equal to (-5, -35, -59)

// Displaying Results
syntaxString = "vectorResult = Point3D.Subtract(point1, point2);";
resultType = "Vector3D";
operationString = "Subtracting a Point3D from a Point3D";
ShowResults(vectorResult.ToString(), syntaxString, resultType, operationString);
