I’ve been trying to recreate the camera system that Google Earth has where the initial place you click on is where your mouse is kept (with a little delay). Through trial and error I’ve reached whats shown in the video below.
Problem 1: I got it so the camera rotates in the correct direction (opposite of the mouse) but it doesn’t rotate enough. Attempt to multiply how much is rotates has caused the camera to move out of control.
Problem 2: It seems to be jumping back and forth from two points. I think that’s because its bouncing around the polygons of the sphere but I am unsure. Other versions of the ‘drag to rotate’ where it simply follows the held left mouse button does not have this issue.
Problem 3: The initial left mouse button press jolts the camera to a new location. I’ve seen other threads on this forum talk about this issue when it comes to them moving a sphere but I haven’t looked to deep into this problem yet.
Problem 4: Just as a aesthetic thing the Google Earth controls lets the user rotate in every direction and can pass through the north and south poles, my version cannot pass through those areas. I assume that its because of the “make Rot from X” node I’m using. Would be helpful if someone could point out another node that could allow rotation on all three axis.

Would appreciate any help on how to improve!
