RasterTek绘制2D Directx11 - 我遇到了麻烦我觉得它是Zbuffer

Question

我在使用Z缓冲区时出现问题，当我从rastertek实现2D纹理tut时，我得到了正在绘制的图像，但是当我将相机移过某个z pos时，2D纹理就不显示了。

这是我的深度模板代码

D3DXMatrixOrthoLH(&m_orthoMatrix, (float)screenWidth, (float)screenHeight, screenNear, screenDepth);

    // Clear the second depth stencil state before setting the parameters.
    ZeroMemory(&depthDisabledStencilDesc, sizeof(depthDisabledStencilDesc));

    // Now create a second depth stencil state which turns off the Z buffer for 2D rendering.  The only difference is 
    // that DepthEnable is set to false, all other parameters are the same as the other depth stencil state.
    depthDisabledStencilDesc.DepthEnable = false;
    depthDisabledStencilDesc.DepthWriteMask = D3D11_DEPTH_WRITE_MASK_ALL;
    depthDisabledStencilDesc.DepthFunc = D3D11_COMPARISON_LESS;
    depthDisabledStencilDesc.StencilEnable = true;
    depthDisabledStencilDesc.StencilReadMask = 0xFF;
    depthDisabledStencilDesc.StencilWriteMask = 0xFF;
    depthDisabledStencilDesc.FrontFace.StencilFailOp = D3D11_STENCIL_OP_KEEP;
    depthDisabledStencilDesc.FrontFace.StencilDepthFailOp = D3D11_STENCIL_OP_INCR;
    depthDisabledStencilDesc.FrontFace.StencilPassOp = D3D11_STENCIL_OP_KEEP;
    depthDisabledStencilDesc.FrontFace.StencilFunc = D3D11_COMPARISON_ALWAYS;
    depthDisabledStencilDesc.BackFace.StencilFailOp = D3D11_STENCIL_OP_KEEP;
    depthDisabledStencilDesc.BackFace.StencilDepthFailOp = D3D11_STENCIL_OP_DECR;
    depthDisabledStencilDesc.BackFace.StencilPassOp = D3D11_STENCIL_OP_KEEP;
    depthDisabledStencilDesc.BackFace.StencilFunc = D3D11_COMPARISON_ALWAYS;

继承了zBuffer的代码

void D3DClass::TurnZBufferOn()
{
    m_deviceContext->OMSetDepthStencilState(m_depthStencilState, 1);
    return;
}


void D3DClass::TurnZBufferOff()
{
    m_deviceContext->OMSetDepthStencilState(m_depthDisabledStencilState, 1);
    return;
}

我一直坚持太久了，请帮忙!!!
