What It Does

This kind of platform is useful when you do not want to run COLMAP or local trainers. The value is convenience: upload media, let the service process it, and get a shareable result.

For professional pipelines, confirm export options and long-term hosting needs before depending on any cloud platform as the only copy of your model.

How To Use It In 3DGS

  • Prepare a stable phone, camera, or drone capture.
  • Upload through the platform’s reconstruction flow.
  • Inspect the generated scene and compare it against the original capture intent.
  • Download, share, or reprocess according to the platform’s available options.

Things To Watch

  • Cloud services can change limits, pricing, and export support.
  • Keep your own source images or video outside the platform.
  • Check privacy and licensing terms before uploading sensitive spaces.

Use It Carefully

  • For Chinese-language users, the main value is reducing local setup friction: upload, reconstruct, view, and share from one platform.
  • Before using it for a paid delivery, run a small test scene and confirm whether export, hosting, and sharing behavior match the job requirements.
  • Keep source media and exported assets under your own project folder, because cloud reconstruction services should not be your only archive.
