4月1日的3D Model Viewer应用程序分析

This app allows you to view 3D models that you have downloaded, or open 3D models directly from your browser. Tap and drag to rotate the model, or pinch to zoom. Tap the VR button at the bottom of the display to switch to VR mode, and view the model in your favorite VR headset, such as Cardboard or Daydream. Supports STL, OBJ, and PLY models. Once installed, the app can become the default handler for opening these types of files from any other app, including your browser or file manager.
