The wider my object, the less sensitive my zoom is. If my object is very narrow, I can zoom in and see my object in very close-up detail. However, if my object is very wide, the zoom is not very sensitive and the object never allows itself to be zoomed in to a very close perspective. Once I zoom in a lot, the object begins to dissappear.
Do you have any suggestions as to an algorithm that would allow equal zoom sensitivity regardless of model size?
