How to Obtain iphone_pointcloud.ply?

[YanLin02]

In scene/dataset_readers.py, the following line references iphone_pointcloud.ply:

GLS/scene/dataset_readers.py

Line 230 in f6f1690

ply_path0 = os.path.join(path, "iphone_pointcloud.ply")

I noticed this file seems to be crucial for generating the point cloud sparse/0/points3D.ply. Could you kindly share how to obtain or generate iphone_pointcloud.ply?

Additionally, would it be possible to use files like points3D.bin as an alternative?

Thank you in advance for any guidance you can provide!
