DirectX10의 깊이 버퍼가 작동하지 않습니다.

Question

DirectX10에서 장면을 만들려고하고 있는데 왜 어떤 이유로 zbuffer (깊이 버퍼)가 작동하지 않는 것 같습니다. 여기

// Initialize the description of the depth buffer.

{ 
    return false; 
} 

// Bind the render target view and depth stencil buffer to the output render pipeline. 
m_pDevice->OMSetRenderTargets(1, &m_pRenderTargetView, m_pDepthStencilView); 

// Setup the raster description which will determine how and what polygons will be drawn. 
rasterDesc.AntialiasedLineEnable = true;

그리고 내 장면에서 모습입니다 : : 여기가 z 버퍼를 설정 한 코드는 내가 단계 나를 통해 단계로 자원 (http://msdn.microsoft.com/en-us/library/windows/desktop/bb205074(v=vs.85).aspx)를 사용 http://imgur.com/UsaURcR

가 있지만입니다 지금 그것이 작동하지 않는 이유에 관해서는 꽤 혼란 스럽습니다.

어떤 도움을 주시면 감사하겠습니다.

DXGI_FORMAT_D32_FLOAT 

2> 그리고 모델에 따라, true로 설정 rasterDesc.FrontCounterClockwise을 시도 할 수 있습니다 : 같은

Answer 1

1> 귀하의 depthBufferDesc 및 depthStencilViewDesc 형식이어야합니다.

ViewPort.MinDepth = 0.0f; 
ViewPort.MaxDepth = 1.0f; 

4> 그리고 당신은 당신의 카메라에 비행기를 클리핑 근처를 확인해야 :

rasterDesc.FrontCounterClockwise = true; 

3> 당신이 설정 한 뷰포트 있는지 확인하십시오. 값은 0보다 커야합니다.
