In the past, I've always hated that non-Mac apps (e.g. CAD programs, Google Maps, etc.) misinterpret the scroll ball on my Mighty Mouse, or two-finger gestures on the trackpad, as zoom and not pan.
But there is a certain convenience to being able to zoom precisely with these gestures. I'd like to interpret vertical scroll as zoom in my 3D app, if the user is holding down a meta key (or is otherwise in a zoom mode). I'm using SCNView, which AFAICT has no zoom functionality. I'm hoping I an intercept the scroll events and use that to reposition my camera, but I don't actually know how to do that. That is, what's the NSView method to override to capture scroll events? Is it -scrollWheel:, or For robustness, I'd like to have any momentum continue to apply to the zoom operation, even if the user releases the meta key before the momentum scroll ends. What do you guys think about this UX, pan-vs-zoom interpretations of scroll events?
