我正在尝试寻找最佳解决方案,以使Three.js的性能得到改善。
我想问一个在服务器端渲染中尝试过Three.js的人,以及
性能提高。
我的three.js项目在场景中包含5个glb文件。每个文件大约1MB。
到目前为止,我已经改善了。
速度索引优先
有意义的绘画
使用webpack
**缩小所有JavaScript并将其包含到一个文件中。
**对所有纹理使用下一代图像wep。
**能够将gzip压缩到我的服务器上
此外,为了提高加载速度,而不是在一开始就加载所有5个glb模型, 首先加载1或2,然后在用户需要时加载其余模型。
减少风扇的声音(CPU原因)
我只为用户互动设置了动画

animate();
}, true);
