如何在three.js中使用不同的相机渲染相同的场景? [英] How to render the same scene with different cameras in three.js?

问题描述

我设置了一个场景，我希望两台摄像机以不同的角度、正面和视角观看同一场景.背部.我试过这样的事情:

I had a scene set up and I want two cameras watch the same scene at a different angle, front & back. I tried something like this:

renderer.setViewport(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT/2);
renderer.render(scene, camera);

renderer.setViewport(0, SCREEN_HEIGHT/2, SCREEN_WIDTH, SCREEN_HEIGHT/2);
renderer.render(scene, testcamera);

但是返回的第二个视图从未出现过.知道为什么吗?

But the 2nd view which is back never showed up. Any idea why?

推荐答案

我收藏了几个例子，有一个使用渲染管理器的有趣帖子:

A couple of examples I have bookmarked, there is an interesting post using a render manager:

也在 three.js 示例中:
