For more info about debugging apps, see Using the debug layer to debug apps. If we use the debug build, we also pass the D3D11_CREATE_DEVICE_DEBUG flag. We pass the D3D11_CREATE_DEVICE_BGRA_SUPPORT flag to the Flags parameter to make Direct3D resources interoperate with Direct2D. So, to get the highest feature level available, we list the D3D_FEATURE_LEVEL array entries from highest to lowest. Direct3D walks the array in order and returns the highest supported feature level. We specify levels 9.1 through 11.1 in the array of D3D_FEATURE_LEVEL values. To create the Direct3D device, we call the D3D11CreateDevice function. To use the Direct3D API to render a scene, we must first create a Direct3D device that represents the display adapter. OMSetRenderTargets binds the render target to the output-merger stage to specify the render target as the output target.Īfter the sample app is started, it initializes and loads, and is then ready to run. If you declare ID3D11RenderTargetView with ComPtr, you can then use ComPtr’s GetAddressOf method to get the address of the pointer to ID3D11RenderTargetView (**ID3D11RenderTargetView) to pass to ID3D11DeviceContext::OMSetRenderTargets. We can then use those variables to access the ComPtr class and its members. We declare Direct3D interface variables with the ComPtr smart pointer template from the Windows Runtime C++ Template Library (WRL), so we can manage the lifetime of those variables in an exception safe manner.

Declaring Direct3D interface variables with ComPtr You also need basic experience with graphics programming concepts. We assume that you are familiar with C++.

Objective: To set up DirectX resources in a C++ Universal Windows Platform (UWP) app and to display a solid color. Here, we show you how to create a Direct3D device, swap chain, and render-target view, and how to present the rendered image to the display.
