如何在JavaFX中将GUI叠加在3D场景上？ [英] How to overlay GUI over 3D scene in JavaFX?

问题描述

我在JavaFX中有一个3D场景，需要在3D场景上叠加GUI。我尝试将按钮和文本添加到场景中，但它们总是作为3D对象出现在3d视图中。我环顾四周，还没找到怎么做。唯一的解决方法是创建一个全新的窗口并将设置放在那里但在这种情况下不是一个选项。感谢您的帮助!!

I have a 3D scene in JavaFX and need to overlay GUI over the 3D scene. I have tried adding buttons and text to the scene but they always appear in the 3d view as 3D objects. I have looked around and haven't found how to do it. The only workaround would be creating a whole new window and putting the settings there but that isn't an option in this case. Thanks for the help!!

推荐答案

您正在寻找的最佳解决方案是 SubScene ，内置JavaFX 容器：

The best solution for what you are looking for is the SubScene, a built-in JavaFX container:

SubScene类是场景图中内容的容器。 SubScene提供场景的不同部分的分离，每个部分都可以使用不同的摄像机，深度缓冲区或场景抗锯齿进行渲染。 SubScene嵌入到主场景或另一个子场景中。

The SubScene class is the container for content in a scene graph. SubScene provides separation of different parts of a scene, each of which can be rendered with a different camera, depth buffer, or scene anti-aliasing. A SubScene is embedded into the main scene or another sub-scene.

如果你看一下 3DViewer 项目，你会发现它就像您发布的图片：

If you have a look at the 3DViewer project, you'll find it is like the pictures you have posted:
