Currently the Scroll Wheel viewport zoom / camera closeup move does not work with Rhino standard view manipulation degradation (Dynamic Display bounding box mode, skylight shadows degradation, maybe more view manipulation optimizations that I am not aware of). That results in much slower navigation while using scroll wheel, vs. for example zooming in with Ctrl+RMB-drag.
I understand that each scroll wheel step is basically a single view change, and there is no in-between smooth mode while scrolling, like when holding RMB and rotating the view, so Rhino does not know that we are in the middle of zooming action.
I was wondering if this could be implemented. Scroll Wheel action is hardly ever a single step. Most of the times user would keep scrolling to get the view where it needs to be, sometimes back-and-forth.
What if, the first detected scroll wheel step would trigger the view degradation mode as the other view changes do, and then keep it on for another 150-200ms. If no more scrolling happens, switch back to regular display, otherwise if user keeps scrolling the view stays degraded, until 150-200ms passes from the last scroll wheel movement.
@DavidEranen - is that something you think would be possible?
