如何在Scene Kit中为同一场景使用多个摄像头 [英] How to use multiple cameras for the same scene in Scene Kit

问题描述

我有2个SCNViews彼此相邻，两个都应该显示相同的场景，但通过不同的相机。
在我看来，Scene Kit使用的节点与节点层次结构中最高的相机一样，所以我尝试了类似的东西

I have 2 SCNViews next to each other and both should show the same scene but through different cameras. It seems to me that Scene Kit uses that node with a camera that is highest in the node hierarchy so I tried something like that

    leftSceneView.scene?.rootNode.addChildNode(scene.rootNode)
    rightSceneView.scene?.rootNode.addChildNode(scene.rootNode)

    leftSceneView.scene?.rootNode.addChildNode(cameraNodeLeft)
    rightSceneView.scene?.rootNode.addChildNode(cameraNodeRight)

但是我得到了错误消息 [SCNKit ERROR]不允许从场景中删除场景的根节点，它根本不起作用。

but I got the error message [SCNKit ERROR] removing the root node of a scene from its scene is not allowed and it did not work at all.

有人建议如何实现这一目标吗？

Has anybody a suggestion how I can achieve that?

推荐答案

设置视图以使用SCNView的pointOfView属性渲染场景。

Set the point of view to render the scene with the "pointOfView" property of the SCNView.

scnView.pointOfView = cameraNodeLeft;

scnView.pointOfView = cameraNodeLeft;
