more data?

[jeannotes]

hi, thanks for this amazing repo,
but I do have some more questions,

1. how to get more tiff datas? I do want to generate more imgs
2. how to get latlonalt_bbx parameters, this is a known parameter? seems that you use the inside value to create camera parameters.
3. how do you generate the videos like "./readme_resources/novel_view.gif" "https://user-images.githubusercontent.com/21653654/153779703-36b50265-ae3b-41ac-8139-2e0bf081f28d.mp4"
   hope that you can add more scripts.

thanks!
