Create an Additional Swap Chain
This example demonstrates how to create an additional swap chain using the SwapChain class. Additional swap chains are useful for supporting multiple viewports; for example, a single window partitioned into four sub-windows, each with different views of the same scene.
In Microsoft DirectX 9.0 for Managed Code, each Device is created with a default swap chain known as the implicit swap chain. Using the SwapChain class allows creation of additional swap chains for rendering operations.
To create a new swap chain:
- Create an instance of the PresentParameters class, or use an existing instance and set the presentation properties to the values you need for the swap chain.
- Then create a swap chain object using the SwapChain class constructor.
In the following C# code example, device is assumed to be the rendering Device.
[C#] // Create a swap chain using an existing instance of PresentParameters. SwapChain sc = new SwapChain(device, presentParams);
