Public Property ViewMatrix As Matrix3D

Property Value

Matrix3D

A Matrix3D that represents the position, look direction and up vector for the camera.

Examples

The following code creates a MatrixCamera and sets the ViewMatrix and ProjectionMatrix properties.

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

Remarks

This property is useful for applications that implement their own projection matrix calculation.

The camera properties specified by this matrix might differ from the top-level transform of the Model3D hierarchy.
