Multiply(Double, Vector3D)
public:
static System::Windows::Media::Media3D::Vector3D Multiply(double scalar, System::Windows::Media::Media3D::Vector3D vector);public static System.Windows.Media.Media3D.Vector3D Multiply(double scalar, System.Windows.Media.Media3D.Vector3D vector);static member Multiply : double * System.Windows.Media.Media3D.Vector3D -> System.Windows.Media.Media3D.Vector3DPublic Shared Function Multiply (scalar As Double, vector As Vector3D) As Vector3D參數
- scalar
- Double
標量要乘以。
傳回
乘以 和 scalar的結果vector。
範例
以下範例說明如何將純量乘以結構 Vector3D 。
// Multiplies a Vector3D by a Scalar using the static Multiply method.
// Returns a Vector3D.
Vector3D vector1 = new Vector3D(20, 30, 40);
Double scalar1 = 75;
Vector3D vectorResult = new Vector3D();
vectorResult = Vector3D.Multiply(vector1, scalar1);
// vectorResult is equal to (1500, 2250, 3000)
' Multiplies a Vector3D by a Scalar using the static Multiply method.
' Returns a Vector3D.
Dim vector1 As New Vector3D(20, 30, 40)
Dim scalar1 As Double = 75
Dim vectorResult As New Vector3D()
vectorResult = Vector3D.Multiply(vector1, scalar1)
' vectorResult is equal to (1500, 2250, 3000)
