Recently, I had occasion to be moving models on a sphere. To be more precise, I was moving ships on a globe to show travels. Well, guess what? The program moves models from point A to point B in a straight line. The ships kept submerging. Unless I put the ships well above the water, I have to change their location (z as well as x and y) very frequently as they move along the timeline. If I put them well above the water, the angle of view sometimes makes them look like they are very far from where I wanted them to be. Sometimes they look like they are on the land. This becomes an issue especially as they are approaching a port. Does anyone have any ideas? Is there a spherical geometry button that allows us convert to sperical geometry and insert the circumference of a sphere for the computer to automatically calculate the in-betweens using spherical geometry? I don't know much about any of this, but I thought someone else might.
It could be used for a mosquito or fly to roam across a person's nose or some other sphere. There are probably many uses I will never think of.
