Which is the minimum feature level for DirectX?
The feature level tells DirectX the minimum level of hardware your app supports, with D3D_FEATURE_LEVEL_9_1 as the lowest feature set and D3D_FEATURE_LEVEL_11_1 as the current highest. You should support 9_1 as the minimum if you want to reach the widest possible audience.
How to work with device resources in Direct3D?
Get a CoreWindow for your app. Get an interface for the Direct3D device and context. Create the swap chain to display your rendered image in the CoreWindow. Create a render target for drawing and populate it with pixels. Present the swap chain! The first thing we need to do is create a window.
What is the role of DXGI in Windows Store?
Understand the role of the Microsoft DirectX Graphics Infrastructure (DXGI) in your Windows Store DirectX game. DXGI is a set of APIs used to configure and manage low-level graphics and graphics adapter resources. Without it, you’d have no way to draw your game’s graphics to a window.
How to use Direct3D with the GPU?
The first step to using Direct3D is to acquire an interface for the Direct3D hardware (the GPU), represented as instances of ID3D11Device and ID3D11DeviceContext. The former is a virtual representation of the GPU resources, and the latter is a device-agnostic abstraction of the rendering pipeline and process.
How to use DXGI to manage GPU resources?
Think of DXGI this way: to directly access the GPU and manage its resources, you must have a way to describe it to your app. The most important piece of info you need about the GPU is the place to draw pixels so it can send those pixels to the screen.
When to use the HWND pointer in createwindow?
When you call CreateWindow, you get back an opaque pointer to the window called an HWND; you’ll need to keep the HWND pointer and use it any time you need to reference the window, including destroying or recreating it, and (especially important) when creating the DXGI swap chain you use to draw in the window.
