Public Property ProjectionMatrix As Matrix3D

Property Value

Matrix3D

Matrix3D that specifies the projection transformation.

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.

This property transforms the coordinate system from camera space to a normalized cube where the X and Y coordinates range from -1 to 1 and the Z coordinate ranges from zero to 1. The minimum and maximum Z coordinates in camera space are defined by how the projection matrix transforms the Z coordinate.
