Vulkan Depth 缓冲区是 0 或 1永远不要介于两者之间

如何解决Vulkan Depth 缓冲区是 0 或 1永远不要介于两者之间

我遇到了深度缓冲区/测试不工作的问题。当我检查 RenderDoc 时，我发现深度缓冲区始终为 1，其中已呈现对象：depth_example。我期待在黑白之间有一种平滑的渐变。

从昨天开始我一直在尝试解决这个问题，并且尝试了很多事情，例如：更改管道设置、更改渲染通道设置、检查帧缓冲区和深度纹理设置，甚至更改投影/视图矩阵。

验证层没有抛出任何错误，我一直在使用 RenderDoc 进行测试/调试。

如果有人想查看，我已经保存并上传了应用程序的 RenderDoc 捕获，它处于我尝试进行更改之前的状态：RenderDoc Capture

我将在下面发布一些我认为相关的代码，但在此之前我应该提到我正在使用 GLM 创建带有 GLM_FORCE_DEPTH_ZERO_TO_ONE + GLM_FORCE_LEFT_HANDED 定义的渲染矩阵。
