how to obtain the point cloud

[Beilinlin]

Hi! I would like to ask whether the point cloud initialization is done using COLMAP, rather than obtaining the point cloud through reprojection from predicted depth maps? If so, since you have used Depth-Anything to predict the depth maps, why not utilize these depth maps to obtain the point cloud through reprojection? Wouldn't this approach yield more point clouds and be faster? @ZhihaoPENG-CityU @XGGNet @yifliu3 @LiuHengyu321
