DirectX11 2窗口渲染

本文介绍了DirectX11 2窗口渲染的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

如何使用DirectX将对象渲染到2个单独的窗口中？

How can I render my objects with DirectX into 2 separated windows?

推荐答案

您需要创建一个SwapChain和RenderTargetView每个窗口。

You need to create one SwapChain and RenderTargetView for every window.

1如果您通过CreateDeviceAndSwapChain创建设备，则需要先获取IDXGIFactory

1 if you created your device via CreateDeviceAndSwapChain you need to obtain IDXGIFactory first

IDXGIDevice * device;
d3ddevice->QueryInterface(__uuidof(IDXGIDevice), (void**)&device);

IDXGIAdapter * adapter;
device->GetParent(__uuidof(IDXGIAdapter), (void**)&adapter);

IDXGIFactory * factory;
adapter->GetParent(__uuidof(DDXGIFactory), (void**)&factory);

使用DXGIFactory，您可以为新窗口创建其他交换链

With DXGIFactory you can create additional swapchain for new window

factory->CreateSwapChain(g_pd3dDevice, &sd, &g_pSwapChain2);

然后创建渲染目标视图

ID3D11Texture2D* pBackBuffer = NULL;
hr = g_pSwapChain2->GetBuffer( 0, __uuidof( ID3D11Texture2D ), ( LPVOID* )&pBackBuffer );
if( FAILED( hr ) )
    return hr;

hr = g_pd3dDevice->CreateRenderTargetView( pBackBuffer, NULL, &g_pRenderTargetView );
pBackBuffer->Release();
if( FAILED( hr ) )
    return hr;

最后只需设置渲染目标并绘制一些东西！

And finally just set your render target(s) and Draw something!

g_immediateContext->OMSetRenderTargets(1, &g_RenderTargetView, NULL);
....

我希望这会有所帮助。
