问题描述
似乎多重采样纹理进行多重采样，因此反锯齿。
我想使用多重采样纹理。
和这样的CreateTexture。
但是ID3D11ShaderResourceView创建失败。
It seems that multisample texture do multisampling, so Anti-Aliased.
I want to use multisample texture.
And CreateTexture like this.
But ID3D11ShaderResourceView create fail.
// 我像这样创建了SwapChain。

CreateShaderResourceView（）函数错误代码'E_INVALIDARG一个或多个参数无效。'
是否有任何样本使用多重采样纹理？
CreateShaderResourceView() function Error Code 'E_INVALIDARG One or more arguments are invalid.'
Is there any sample use multisample texture?
推荐答案
使用此标志指定翻转演示模型并指定DXGI持久保存内容调用
IDXGISwapChain1 :: Present1 后的后台缓冲区。
此标记不能用于多重采样。
Use this flag to specify the flip presentation model and to specify that DXGI persist the contents of the back buffer after you callIDXGISwapChain1::Present1. This flag cannot be used with multisampling.
最后一句很重要。
但首先要做的是启用调试层。您可以在
，如果你将D3D11_CREATE_DEVICE_DEBUG放在flags参数中，那么它将启用调试运行时。当您的应用程序附加调试器时，调试运行时将提供有关错误的更多信息。如果您使用Visual Studio作为调试器是
，那么您可以在输出窗口中看到此信息。
But the first thing you should do is to enable the debug layer. You can do this in the call toD3D11CreateDevice, if you put D3D11_CREATE_DEVICE_DEBUG in the flags parameter then it will enable the debug runtime. When you have a debugger attached to your application, the debug runtime will provide more information about what went wrong. If you are using Visual Studio as the debugger, then you can see this information in the output window.
