scene rotation

[Bin-ze]

When I use Vuer to visualize a 3dgs scene and drag the mouse, the scene will rotate around the specified world axis.

before：

after：

But this will cause the camera to see through the wall in indoor scenes. I wish I could keep the scene the same and change the camera position.

Therefore I want to know how I can set up the rotation to keep the camera's origin fixed in the camera coordinate system and just change the R matrix of the camera coordinate system. This simulates the effect of humans walking and turning in the scene.
