Relationship between the Gaussian model transformation and camera pose change？

[Mysterious-handsome-man]

Thank you for your excellent work ！I have a question while reviewing the code：
What is the relationship between the Gaussian model's XYZ rotation+translation transformations from time
t to 𝑡+1 and the changes in the camera's pose? In other words, once you have the Gaussian model's pose change from the current time to the next, how to convert it into the changes in the camera's pose?

Hello! Have you solved this problem? I also have the same confusion. If you have solved it, can you share it
