How to get the well-reconstructed point cloud as initialization

[Tracy-coder]

As mentioned in the "Limitations and Future Work" section of the paper, "Our current approach
requires a well-reconstructed point cloud as initialization."
I'm wondering about how to get this well-reconstructed point cloud.
Looking forward to any answers~

We currently run a 3DGS reconstruction process first and use the reconstructed gaussian pointcloud as initialization. A dense reconstruction from Colmap also works well on most cases.
