Directx11 Project不会显示图形输出

时间：2018-04-13 12:29:50

标签： c++ directx directx-11 hlsl

我对Directx很新，所以我接下来不知道这里发生了什么。

我已确认窗口和DirectX API的初始设置和激活已成功。但是，虽然绘图和更新功能似乎完全可操作，但它们仍然无法显示输出。我检查了链接器，我的对象类，我的效果文件，基本上整个项目已经十几次了。请帮忙！

检查您的代码并将其与我过去为DirectX 11渲染编写的代码进行比较，您至少缺少一件事 - 深度/模板状态。如果你决定使用没有它的深度/模板缓冲区，我不确定GPU会做什么，但它看起来是你的系统调用（这不起作用）和我的系统调用的调用之间的唯一区别（确实如此）。

您可以使用ID3D11Device::CreateDepthStencilState创建深度/模板状态，并使用ID3D11DeviceContext::OMSetDepthStencilState将其设置为管道。此函数与ID3D11DeviceContext::OMSetBlendState的工作方式相同，即传递nullptr，NULL或0，因为状态对象将绑定默认状态。
