This script provides a robust conversion tool for exporting Scaffold-GS models (PLY + TorchScript MLPs) to the standard 3DGS PLY format. It supports pruning, SH color fitting, background/sky boosting, and flexible output directory management. All code comments, docstrings, and CLI help are in English, and the output workflow is user-friendly for integration and batch processing.

Key Features

  • Converts Scaffold-GS PLY + MLPs to standard 3DGS PLY with pruning and SH fitting.
  • Background/sky boosting and anchors-only mode supported.
  • Output is organized in timestamped subdirectories for reproducibility.

This utility aims to facilitate downstream 3DGS workflows and improve interoperability with other Gaussian Splatting tools.
