For desktop applications, SharpDX provides a helper class
SharpDX.Windows.
RenderLoop
that implements the rendering loop and processes any
window messages for us. The following code demonstrates its use within
a
D3DApplicationDesktop.Run
implementation:
public override void Run()
{
SharpDX.Windows.RenderLoop.Run(Window, () => {
... Render frame
Present();
});
}

To take advantage of the lifecycle management built into the
Common.
DeviceManager
class and the
Common.D3DApplicationBase
abstract base
class, we can optionally override the following methods in our
D3DApp
implementation:
// Override / extend the default SwapChainDescription1
protected override SwapChainDescription1
CreateSwapChainDescription()
{ ... }
// Event-handler for DeviceManager.OnInitialize
protected override void CreateDeviceDependentResources(DeviceManag
er deviceManager)
{ ... }
// Event-handler for D3DApplicationBase.OnSizeChanged
protected override void CreateSizeDependentResources(D3DApplicatio
nBase app)
{ ... }

We are now able to create an instance of
D3DApp
, initialize the Direct3D device and
resources, and then start the application loop. To ensure all resources are correctly
released, we can use a
using
code block. The following code snippet shows how this
might be done:
using (var app =
new D3DApp(form)
)
{
// Only render frames at the maximum rate the
