我遇到了DirectX10 + C ++问题。
基本上我们处于渲染的早期阶段，由于某种原因，我们的深度模板似乎无法理解我们的模型。基本上，这是我们正在做的一切：
模型，着色器和纹理都加载并正常工作（但是如下面的屏幕截图所示），深度模板显然没有完成其工作，并且着色器正在错误的位置使用。我还包括了我们的初始化方法，以防你需要它来解决它。我们相信我们已经尝试了几乎所有的东西，但是知道我们的运气，我们可能错过了一行重要代码^。^
我们还看到其他人有同样的问题，但是他们的修复不起作用（他们的问题是他们已经将近剪裁平面设置为0.0，但是我们的不是0.0因此这不是问题）
提前致谢！

}答案 0 :(得分：1)
我修好了，感谢catflier向正确的方向点头。事实证明，我实际上太早地发布了光栅化器状态，无法使用深度模板。
对于遇到同样问题的人，我会在这里留下这个答案。
