如何将相同的实体插入到Scene3DQML 中的多个 s 中?
(很可能很清楚我对 QML 很陌生)
我想创建类似于Multi Viewport QML Example的东西,除了我想在不同的布局中使用视口(例如SplitView)。
最终,我希望我的实体(Mesh或SceneLoader实体)完全在我的视图(我的Scene3D)之外创建,并且能够在多个视图中显示相同的数据而无需副本。
我没有太多运气将 aLayout放入 aScene3D中,即便如此,这也会限制我在其他地方显示相同的数据。我根本不知道如何在视图之外定义我的数据,特别是因为我不知道如何附加到components//属性data。children
例如,在下面的(长)示例中,我想出了如何通过设置将其注入到torusMesh2之外来定义,但我不知道如何将它注入到两个sScene3D.parentscene3DRightEntityScene3D
