COLMAP output format

Hello,

Excellent work, congratulations. 

I would kindly like to ask if there is a way to support the standard COLMAP output.
For example like those in the MipNerf360 data set https://jonbarron.info/mipnerf360/
[ it contains an image directory and 3 files (cameras.txt, points.txt, points3D.txt)

Thank you.
Sincerely
Barnabas Takacs
