3D 未在 WPF 应用程序中呈现
我正在尝试使用下面的代码渲染 3D 对象。 但是当我运行该应用程序时,什么也没有显示。似乎一片空白。我错过了什么吗?

I am trying to render 3D object using the below code.
But when I run the application, nothing is displayed. It seems to be blank. Am I missing anything?

它似乎在 Kaxaml 中对我来说渲染得很好。
也许您应该尝试不同的机器或使用 Kaxaml 来查看是否得到任何结果。此时,可能有很多事情。
编辑:我注意到我没有复制
Grid.RowDefinitions
。当我添加它们时,它会剪辑视口。如果你把它们去掉,它还能工作吗?It appears to render fine for me in Kaxaml.
Perhaps you should try a different machine or use Kaxaml to see if you get any result at all. At this point, it could be any number of things.
EDIT: I noticed that I didn't copy the
Grid.RowDefinitions
. When I add them, it clips the viewport. If you remove those, does it work?我尝试在 WPF 应用程序中渲染 Viewport3D,并且已成功渲染。它向我展示了一个金字塔网格。
从上面的代码中,您会看到一个空白屏幕,因为您没有定义页面高度和宽度。
这是我为您的页面提供的解决方案(请添加您的页面高度和宽度属性,如下所示):
I try to render your Viewport3D in WPF application and it's successfully rendered. It shows me a pyramid mesh.
From your code above, you get a blank screen because you are not defining your page height and width.
Here is my solution for your page (Please add your page height and width properties as follow) :
