窗口化时DirectX11交换链纹理渲染问题？

Question

我正在编写一个基于DirectX11的游戏框架，但是我遇到了问题，我的纹理在屏幕上显示得很糟糕，这是一个截图：

正如你所看到的那样，图像并不完美，但我注意到只有当我将交换链初始化为窗口化时才会发生这种情况，如果我不这样做并且我将其初始化为全屏，则精灵正确显示，即使在运行时我从全屏切换到窗口仍然显示正确，这是屏幕上显示的图像：

我的交换链初始化：

RECT dimensions;
GetClientRect(game->Window, &dimensions);

unsigned int width = dimensions.right - dimensions.left;
unsigned int height = dimensions.bottom - dimensions.top;

D3D_DRIVER_TYPE driverTypes[] =
{
    D3D_DRIVER_TYPE_HARDWARE,
    D3D_DRIVER_TYPE_WARP,
    D3D_DRIVER_TYPE_REFERENCE,
    D3D_DRIVER_TYPE_SOFTWARE
};

unsigned int totalDriverTypes = ARRAYSIZE(driverTypes);

D3D_FEATURE_LEVEL featureLevels[] =
{
    D3D_FEATURE_LEVEL_11_0,
    D3D_FEATURE_LEVEL_10_1,
    D3D_FEATURE_LEVEL_10_0
};

unsigned int totalFeatureLevels = ARRAYSIZE(featureLevels);

DXGI_SWAP_CHAIN_DESC swapChainDesc;
ZeroMemory(&swapChainDesc, sizeof(swapChainDesc));
swapChainDesc.BufferCount = DXGI_SWAP_EFFECT_SEQUENTIAL;
swapChainDesc.BufferDesc.Width = width;
swapChainDesc.BufferDesc.Height = height;
swapChainDesc.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
swapChainDesc.BufferDesc.RefreshRate.Numerator = 60;
swapChainDesc.BufferDesc.RefreshRate.Denominator = 1;
swapChainDesc.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT;
swapChainDesc.OutputWindow = game->Window;
swapChainDesc.Windowed = true;
swapChainDesc.SampleDesc.Count = 1;
swapChainDesc.SampleDesc.Quality = 0;

unsigned int creationFlags = 0;

#ifdef _DEBUG
creationFlags |= D3D11_CREATE_DEVICE_DEBUG;
#endif

HRESULT result;
unsigned int driver = 0;

pin_ptr<IDXGISwapChain*> swapChainPointer;
swapChainPointer = &swapChain_;

pin_ptr<ID3D11Device*> d3dDevicePointer;
d3dDevicePointer = &d3dDevice_;

pin_ptr<D3D_FEATURE_LEVEL> featureLevelPointer;
featureLevelPointer = &featureLevel_;

pin_ptr<ID3D11DeviceContext*> d3dContextPointer;
d3dContextPointer = &d3dContext_;

for (driver = 0; driver < totalDriverTypes; ++driver)
{
    result = D3D11CreateDeviceAndSwapChain(0, driverTypes[driver], 0, creationFlags, featureLevels, totalFeatureLevels,
        D3D11_SDK_VERSION, &swapChainDesc, swapChainPointer,
        d3dDevicePointer, featureLevelPointer, d3dContextPointer);

    if (SUCCEEDED(result))
    {
        driverType_ = driverTypes[driver];
        break;
    }
}

这是切换全屏的代码：

swapChain_->SetFullscreenState(isFullScreen, NULL);

其中IsFullScreen是传递给containsig函数的布尔值。

任何人都可以帮助我吗？提前谢谢！

修改

解决：

我在创建窗口时更改了WS_OVERLAPPED参数：

RECT rc = { 0, 0, WindowWidth, WindowHeight };
AdjustWindowRect(&rc, WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU, FALSE);

LPCTSTR title = Utilities::StringToLPCSTR(Title);

HWND hwnd = CreateWindowA("BSGame", title, WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU, CW_USEDEFAULT, CW_USEDEFAULT, rc.right - rc.left, rc.bottom - rc.top, NULL, NULL, windowHandler, NULL);

到WS_OVERLAPPEDWINDOW

Answer 1

当您在SwapChain上调用SetFullScreen时，您只需要更改模式。

通常在通话结束后，您应该从主表单收到WM_SIZE消息，然后您需要执行以下操作：

释放绑定到交换链的任何相关资源（例如：Texture和RenderTargetView） 确保你也在设备上下文中调用ClearState，因为如果SwapChain仍然绑定到管道，你也会遇到问题（如果绑定到管道，运行时不会销毁资源）。

接下来你在swapchain上调用resize，例如：

 HRESULT result = mSwapChain->ResizeBuffers(0,0,0,DXGI_FORMAT_UNKNOWN,0);

最后，您可以再次查询纹理：

ID3D11Texture2D* texture;
mSwapChain->GetBuffer(0,__uuidof(ID3D11Texture2D),(void**)(&texture));
//Get Buffer does an AddRef on top so we release
texture->Release();

创建一个新的RenderTargetView，并将ViewPort更新为新的大小（从纹理中获取描述）。

Answer 2

就我而言，问题出在窗口创建期间，这是我的情况：

RECT rc = { 0, 0, WindowWidth, WindowHeight };
AdjustWindowRect(&rc, WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU, FALSE);

LPCTSTR title = Utilities::StringToLPCSTR(Title);

HWND hwnd = CreateWindowA("BSGame", title, WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU, CW_USEDEFAULT, CW_USEDEFAULT, rc.right - rc.left, rc.bottom - rc.top, NULL, NULL, windowHandler, NULL);

要解决我已将WS_OVERLAPPED更改为WS_OVERLAPPEDWINDOW
