【整合包】虚无之主

现在平台支持上传和实时预览3d建模，默认在图片后面（因为放在前面有的建模太大会加载缓慢，影响用户第一视觉观感，索性放到图片后面，他们看到的时候也就预加载完成了）

目前支持格式：obj,3ds,stl,ply,gltf,glb,off,3dm,fbx
ps：因为懒，所以上传3d建模文件时，没有弄进度条。如果上传成功他会直接显示文件名

The platform now supports uploading and real-time previews of 3D models. By default, they are loaded behind the images. (Since placing them first can cause slow loading for large models and affect the user's initial experience, we put them behind so they can finish pre-loading by the time the user sees them.)

Currently supported formats: obj, 3ds, stl, ply, gltf, glb, off, 3dm, fbx
P.S. Out of laziness, there is no progress bar when uploading 3D model files. Once the upload is successful, the filename will be displayed directly.
