微信小程序 webview引入three 3d切换场景，ios手机出现闪屏刷新问题

问答 / 0 / 2 / 创建于 2个月前 / 更新于 2个月前

1. 运行环境

  1. 微信小程序 webview 引入three 3D
  2. IOS 手机

2. 问题描述？

使用微信小程序webview 切换 three.js 切换场景的时候出现闪屏刷新的问题，但是在 ios 手机的 safari 游览器可以正常切换。

问题：

  1. 为啥不用threex
    1. 动画里面的灯光、雾、还有动作那些老出现白屏，才用的原生；
    2. 一个场景最低的内存都在 60 MB 左右
  2. 在一个页面切换场景的时候，清除了内存占用

3. 您期望得到的结果？

使用微信小程序webview 可以正确切换 three.js 场景,大佬们有没有解决方案。

4. 代码贴图

在切换场景的时候清除占用内存
