Hello to all,
I'm writing a DirectX10 application and i don't have depth buffering. This is my code:









void Game::InitSwapChain()

{

	DXGI_SWAP_CHAIN_DESC sd;

	sd.BufferCount = 1;

	sd.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;

	sd.BufferDesc.Height = mHeight;

	sd.BufferDesc.Width = mWidth;

	sd.BufferDesc.RefreshRate.Numerator = mRefreshRate;

	sd.BufferDesc.RefreshRate.Denominator = 1;

	sd.BufferDesc.Scaling = DXGI_MODE_SCALING_UNSPECIFIED;

	sd.BufferDesc.ScanlineOrdering = DXGI_MODE_SCANLINE_ORDER_UNSPECIFIED;

	sd.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT;

	sd.Flags = 0;

	sd.OutputWindow = mhWnd;

	sd.SampleDesc.Count = 1;

	sd.SampleDesc.Quality = 0;

	sd.SwapEffect = DXGI_SWAP_EFFECT_DISCARD;

	sd.Windowed = !mFullScreen;

	UINT createDeviceFlags = 0;

#if defined(DEBUG)||defined(_DEBUG)

	createDeviceFlags |=D3D10_CREATE_DEVICE_DEBUG;

#endif

	HR(D3D10CreateDeviceAndSwapChain(NULL,D3D10_DRIVER_TYPE_HARDWARE,0,

								  createDeviceFlags,D3D10_SDK_VERSION,&sd,

								  &mSwapChain,&mDevice));

}

void Game::InitRenderTargetView()

{

	ID3D10Texture2D* backBuffer;

	HR(mSwapChain->GetBuffer(0, __uuidof(ID3D10Texture2D), reinterpret_cast<void**>(&backBuffer)));

	HR(mDevice->CreateRenderTargetView(backBuffer, 0, &mRenderTargetView));

	ReleaseCom(backBuffer);

}

void Game::InitDepthStencilView()

{

	D3D10_TEXTURE2D_DESC dsdesc;

	dsdesc.ArraySize = 1;

	dsdesc.BindFlags = D3D10_BIND_DEPTH_STENCIL;

	dsdesc.CPUAccessFlags = 0;

	dsdesc.Format = DXGI_FORMAT_D24_UNORM_S8_UINT;

	dsdesc.Height = mHeight;

	dsdesc.Width = mWidth;

	dsdesc.MipLevels  = 1;

	dsdesc.MiscFlags = 0;

	dsdesc.SampleDesc.Count = 1;

	dsdesc.SampleDesc.Quality = 0;

	dsdesc.Usage = D3D10_USAGE_DEFAULT;

	mDevice->CreateTexture2D(&dsdesc,NULL,&mDepthStencilBuffer);

	mDevice->CreateDepthStencilView(mDepthStencilBuffer,NULL,&mDepthStencilView);

}



void Game::ClearColorDephtStencil(D3DXCOLOR color,

	FLOAT depth,UINT8 stencil)const

{

	mDevice->ClearRenderTargetView(mRenderTargetView,(FLOAT*)color);

	mDevice->ClearDepthStencilView(mDepthStencilView,

		D3D10_CLEAR_DEPTH|D3D10_CLEAR_STENCIL,depth,stencil);

}



void Game::OnResize(WPARAM wParam,LPARAM lParam)

{

	mWidth = max(LOWORD(lParam),1);

	mHeight = max(HIWORD(lParam),1);

	ReleaseCom(mRenderTargetView);

	ReleaseCom(mDepthStencilView);

	ReleaseCom(mDepthStencilBuffer);

	mStateMachine->OnScreenResize(lParam,lParam);

	HR(mSwapChain->ResizeBuffers(1, mWidth, mHeight, DXGI_FORMAT_R8G8B8A8_UNORM, 0));

	InitRenderTargetView();

	InitDepthStencilView();

	mDevice->OMSetRenderTargets(1, &mRenderTargetView, mDepthStencilView);

	SetViewPort();

}
