How to output the per-frame point cloud or mesh about 4dgaussians

Since Figure 5 in the article also shows the visualizations of point clouds with different training iterations, I guess there are some ways to derive the point cloud.

1. change the argument metioned in "save_iterations" like:
   parser.add_argument("--save_iterations", nargs="+", type=int, default=[2000, 3000, 5000, 7_000, 9000, 10000,12000, 14000, 20000, 30_000, 45000, 60000])
2. you will find results in output/your_checkpoint_dir

P.S: I visualized results in Blender(Open3D also works)

Sorry for disturbing you again. That's not what I'm looking for.

What you provide is to store the static point cloud on different training iterations. Since this is a dynamic Gaussian, what I want is the point cloud of each frame when the dynamic Gaussian is played after training.

I have modified a version myself and it has worked now. Thank you for your answer : )
