DirectX11繪製簡單的三角形

我試圖用DXUT11繪製一個簡單的三角形，但我看不到我窗口中的三角形。
我努力工作，但仍然找不到問題出在哪裏-_-DirectX11繪製簡單的三角形

我已經檢查了D3D函數的每個返回值，並且它們都返回了S_OK。
我可以看到我的窗口顯示出來，背景色是我設置爲清除窗口的顏色，因此它看起來d3d設備是正確創建的，並且後臺緩衝區已呈現到窗口，但是位於哪裏的黃色三角形？
T_T ...............

我的代碼如下：（爲了簡化問題，我已經刪除了所有的檢查S_OK句）

希望有一個人有耐心看完所有這些長碼-_-
和我着色器代碼：

float4 VS(float4 Pos : POSITION) : SV_POSITION 
{ 
    return Pos; 
} 
float4 PS(float4 Pos : SV_POSITION) : SV_Target 
{ 
    return float4(1.0f, 1.0f, 0.0f, 1.0f); // Yellow, with Alpha = 1 
}

程序單獨運行良好，但是當我試圖用PIX跟蹤它，它墜毀並返回以下信息：

只是一個建議，因爲我沒有時間完整閱讀代碼 - 您的訂單是否正確？嘗試交換兩個頂點。 – OlduwanSteve

感謝您的建議，但我已經嘗試過並注意到新的事情發生了...... – Wood

您是否在運行時啓用了調試功能？如果你這樣做，你可能會在調試輸出中得到一個有用的錯誤。 – OlduwanSteve

問題解決了，謝謝大家〜

我清除Z緩存和模板緩衝區「的OnRender」功能，和三角形終於出現了！使用DirectX11的2010年6月的DX SDK中的教程03不會清除「onFrameRender」中的Z緩衝區，但它在顯示三角形時沒有問題。也許有一些細節我錯過了

是的 - 直到教程05才添加深度緩衝區。 :) – Slagh
