Device.BeginScene Method
[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]
Represents the beginning of a scene.
Namespace: Microsoft.WindowsMobile.DirectX.Direct3D
Assembly: Microsoft.WindowsMobile.DirectX (in Microsoft.WindowsMobile.DirectX.dll)
Syntax
'Declaration
Public Sub BeginScene
'Usage
Dim instance As Device
instance.BeginScene()
public void BeginScene()
public:
void BeginScene()
member BeginScene : unit -> unit
Exceptions
| Exception | Condition |
|---|---|
| InvalidCallException | The method call is invalid. This occurs when BeginScene is called while already in a BeginScene and EndScene pair. Never call BeginScene twice without first calling EndScene. |
Remarks
This method attempts to lock the back buffer which is used for drawing graphical objects. Every call to BeginScene should eventually be followed by a call to EndScene before the display is updated with Device.
If the method fails, the device was unable to begin the scene, and there is no need to call EndScene. Calls to EndScene fail if the previous call to BeginScene fails.
Examples
The following code example shows how to begin and end a scene.
Protected Overrides Sub OnPaint(ByVal eventg As PaintEventArgs)
device.Clear(ClearFlags.Target, Color.Black, 0F, 0)
device.BeginScene()
sprite.Begin(SpriteFlags.None)
sprite.Draw(texture, Vector3.Empty, New Vector3(10, 10, 0), &HFFFFFF)
sprite.End()
device.EndScene()
device.Present()
End Sub
protected override void OnPaint(PaintEventArgs eventg)
{
device.Clear(ClearFlags.Target, Color.Black, 0.0f, 0);
device.BeginScene();
sprite.Begin(SpriteFlags.None);
sprite.Draw(texture, Vector3.Empty, new Vector3(10, 10, 0), 0x00ffffff);
sprite.End();
device.EndScene();
device.Present();
}
