MatrixCamera.ViewMatrix 属性

定义

命名空间:

System.Windows.Media.Media3D

程序集:

PresentationCore.dll

作为视图转换矩阵来获取或设置 Matrix3D。

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

属性值

Matrix3D

一个 Matrix3D 表示相机的位置、查找方向和向上向量。

示例

以下代码创建 MatrixCamera 并设置 ViewMatrix 和 ProjectionMatrix 属性。

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

注解

此属性适用于实现其自己的投影矩阵计算的应用程序。

此矩阵指定的相机属性可能与层次结构的 Model3D 顶级转换不同。
