如何将fbx三维模型转成json格式在浏览器中运行加载？
网友回复
将obj文件或者fbx文件转为为 threejs 对应的json文件。 1. 安装node 2. 下载threejs源文件 https://github.com/mrdoob/three.js 3. cmd 切换到 .\three.js\utils\converters 目录下， 可以看到 threejs 提供的两个js文件，fbx2three.js obj2three.js 文件 4. 安装esm cmd 中执行 npm install esm 5. 将obj文件拷贝到目录下，执行命令 node -r esm obj2three.js ws.obj
然后就可以看到ws.json 文件了
