Well, if I understand you correctly you want to change virtual sphere grid size... to do so you'll have to decide in which "mode" you'd like to change it. Variables that are responsible for sphere size are LAT and LON (used in AndroidCamera in core package), they are saved in app properties, and hardcoded in MainActivity below 660 line in onClick methods, so there you can play with it.
I am aware that this app is over-complicated and hard to handle, and I'm not going to explain "logic" behind it at any time soon.
moreover please be aware that this app is build to test and research so, many functionalities might not work or be unstable.
