*** FML:这是 FRAPS。停止了 DX 屏幕录制软件,它可以工作。 特别感谢@zdd 进行了一些 union 测试,这帮助我解决了这个问题。 ***

Remeber: FRAPS + D3D11_CREATE_DEVICE_DEBUG + SampleDesc.Count > 1 don't mix.

我真的是 DX 的新手......就像一个星期前一样。但是这个问题很容易描述,即使我的术语和理解有限。我保持 DEBUG 层打开,因为它提供了有值(value)的反馈。但反过来又造成了一个我无法克服的问题。我花了 1 天时间一根一根地拉头发。

问题

如果我创建一个 D3D11 设备,其中:

vSwapChainDesc.SampleDesc.Count = 4;
vSwapChainDesc.SampleDesc.Quality = 3;

...它在最后的 ->Release() 上崩溃,无论它是哪个对象。完全相同的该死的代码:

vSwapChainDesc.SampleDesc.Count = 1;
vSwapChainDesc.SampleDesc.Quality = 0;

... 顺利清理 COM 引用。更不用说这两个变体在 Release 中都工作正常,没有 DEBUG 标志。

Output 中,我收到一些神秘的错误提示:live children without parents。但是我只有 5 个与 COM 包装器一起使用的 COM 对象。

所以我删除了 COM 包装器,手动为它们中的每一个执行 ->Release()= nullptr。 IMO,错误地发布某些东西是不可能的。在最后的 ->Release() 上,它说它遇到了断点。

那么...还有其他人遇到过这种行为吗?除非其他人经历过完全相同的事情,否则我认为我无法得到答案。太奇怪了...

求助!

If you want me to comment the code to better explain the logic, I will. I get comments mentioning things that are clearly explain the question and code... Maybe I'm not clear enough.

最后的想法

也许某些我没有调用的对象内部有某种释放函数。也许我做错了什么或真的错了。但我是从一个信誉良好的网站上得到的。它与我目前正在阅读的书中的 Hello DirectX! 代码相匹配。

此代码段经过精简和简约。在尝试找出问题时,它是一个更复杂的版本的精简版。另外,我删除了所有 OOP,以便将它放在一个易于理解的代码块中。

Now there's a final question: Is there another way to smooth lines except this SampleDesc one?

PS:它是 Windows 7 x64,VS 2013 + 2014 CTP。并且该卡支持它在调试和 Release模式下工作(边缘平滑)。只有最终版本在 Debug模式下失败。

最佳答案

我不知道你的代码为什么会崩溃,但是我想根据你的代码分享我的一些DirectX编程的经验,:)

  1. 使用 win32 应用程序而不是控制台应用程序
  2. ComRelease函数太复杂了,不需要那么多代码,一行就够了。
  3. 不要将 d3d 指针包装到 ComPointer。

如下所示的更干净的代码,您将摆脱复杂的 COM 内容,并专注于检查崩溃的代码逻辑。
