Counterintuitive mouse interactions

[blurgyy]

Hi, super impressive work!

I found the mouse interaction for camera control very counterintuitive: dragging with primary mouse button horizontally results in the scene to rotate vertically and vice versa. Is this convention used by any other software? As someone familiar with Blender, I find this mapping particularly difficult to adjust to, since it differs from established 3D software conventions.

Update: it seems the mouse interaction when initializing the scene from a COLMAP sparse/ directory is fine. The counterintuitive mouse interaction is only present when the scene is initialized from a transforms.json file.
