MatrixCamera.ViewMatrix 屬性

public:
 property System::Windows::Media::Media3D::Matrix3D ViewMatrix { System::Windows::Media::Media3D::Matrix3D get(); void set(System::Windows::Media::Media3D::Matrix3D value); };

public System.Windows.Media.Media3D.Matrix3D ViewMatrix { get; set; }

member this.ViewMatrix : System.Windows.Media.Media3D.Matrix3D with get, set

Public Property ViewMatrix As Matrix3D

屬性值

A Matrix3D 代表相機的位置、視角方向和向上向量。

範例

以下程式碼會建立 ， MatrixCamera 並設定 ViewMatrix 和 ProjectionMatrix 屬性。

private void SetMatrixCamera(object sender, EventArgs e)
{
    //Define matrices for ViewMatrix and ProjectionMatrix properties.
    Matrix3D vmatrix = new Matrix3D(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1);
    Matrix3D pmatrix = new Matrix3D(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1);

    MatrixCamera mCamera = new MatrixCamera(vmatrix, pmatrix);
    myViewport.Camera = mCamera;
}

Private Sub SetMatrixCamera(ByVal sender As Object, ByVal e As EventArgs)
    'Define matrices for ViewMatrix and ProjectionMatrix properties.
    Dim vmatrix As New Matrix3D(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1)
    Dim pmatrix As New Matrix3D(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1)

    Dim mCamera As New MatrixCamera(vmatrix, pmatrix)
    myViewport.Camera = mCamera
End Sub

備註

此特性對於實作自身投影矩陣計算的應用非常有用。

此矩陣所指定的相機性質可能與階層的頂層轉換 Model3D 不同。
