我尝试使用 DXUT11 绘制一个简单的三角形，但在我的窗口中看不到三角形。
我努力了，但还是找不到问题出在哪里-_-

我检查了 D3D 函数的每个返回值，它们都返回了 S_OK。
我可以看到我的窗口出现了，背景颜色是我设置为清除窗口的颜色，所以看起来 d3d 设备是正确创建的，后台缓冲区被渲染到窗口，但是黄色三角形在哪里？
T_T.......

我的代码如下：（为了简化问题，我删除了所有检查 S_OK 语句）

希望有人有耐心阅读所有这些长代码 -_-
和我的着色器代码：

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
}

该程序单独运行良好，但是当我尝试使用 PIX 跟踪它时，它崩溃并返回以下信息：

问题解决了，谢谢大家~

我在“onRender”函数中清除了Z缓冲区和模板缓冲区，三角形终于出现了！！！DX SDK 2010 年 6 月使用 DirectX11 的教程 03 没有清除“onFrameRender”中的 Z 缓冲区，但显示三角形没有问题。也许我错过了一些细节
