Gets or sets the projection transformation.

Namespace: Microsoft.WindowsMobile.DirectX.Direct3D
Assembly: Microsoft.WindowsMobile.DirectX (in microsoft.windowsmobile.directx.dll)

Syntax

'Declaration
Public Property Projection As Matrix
'Usage
Dim instance As Transforms
Dim value As Matrix

value = instance.Projection

instance.Projection = value

public Matrix Projection { get; set; }

public:
property Matrix Projection {
    Matrix get ();
    void set (Matrix value);
}

/** @property */
public Matrix get_Projection ()

/** @property */
public void set_Projection (Matrix value)

public function get Projection () : Matrix

public function set Projection (value : Matrix)

Not applicable.

Property Value

A Matrix that represents the projection transformation.

Remarks

The default projection transformation Matrix is the identity Matrix.

Example

The following example shows how to use the Projection property. This example is taken from the Direct3D Mobile Matrices Sample.

' For the projection matrix, set up a perspective transform (which
' transforms geometry from 3-D view space to 2-D viewport space, with
' a perspective divide making objects smaller in the distance). To build
' a perspective transform, you need the field of view (1/4 PI is common),
' the aspect ratio, and the near and far clipping planes (which define
' the distances at which geometry should no longer be rendered).
device.Transform.Projection = Matrix.PerspectiveFovLH(System.Convert.ToSingle(Math.PI) / 4, 1.0F, 1.0F, 100.0F)

// For the projection matrix, set up a perspective transform (which

// the aspect ratio, and the near and far clipping planes (which define
// the distances at which geometry should no longer be rendered).
device.Transform.Projection = Matrix.PerspectiveFovLH((float)Math.PI / 4, 1.0f, 1.0f, 100.0f);
