如果一个点在摄像机视图之外，则Three.js线消失 [英] Three.js line disappears if one point is outside of the camera's view

问题描述

我按照文档中的说明创建了一行：
http：// threejs .org / docs / #Reference / Objects / Line 。

但是当其中一个线点位于相机视图之外时，线条会消失。 / p>

我还尝试使用 https：// github。 com / spite / THREE.MeshLine ，但我仍有同样的问题。

我该如何解决？

解决方案

如果更新线的顶点，还必须更新线的边界球体，以便截头锥体剔除才能正常工作。

  line.geometry.computeBoundingSphere（）; 
  

或者，您可以通过设置

$来防止对您的行进行视锥问题剔除b $ b

  line.frustumCulled = false; 
  

three.js r.75

I created a line as explained in the docs: http://threejs.org/docs/#Reference/Objects/Line.

But when one of the line points is outside of the camera's view, the line disappears.

I also tried to use https://github.com/spite/THREE.MeshLine, but I still have the same problem.

How can I fix it?

解决方案

If you update the vertices of your line, you must also update the bounding sphere of your line for frustum culling to work correctly.

line.geometry.computeBoundingSphere();

Alternatively, you can prevent frustum culling of your line by setting

line.frustumCulled = false;
