Right click = zoom in

Post by lshachar » 27 Nov 2019, 14:17

Suggestion:
left click+drag an object = drag scene (Pan button)
middle mouse button+drag an object = rotate scene (Rotate button)
I'm suggesting right click+move mouse up or down = zoom in / out (Shift button)

(The normal scroll wheel on the mouse zooms in/out, but the default zoom step is very small. I suggest users to go to System/usrset.txt and change mouseWheelZoomFactor to ~10, to make the scroll wheel zoom much faster. Coopelia, Maybe change the default value?)

I'm also wondering if the "Fly button" was deprecated at some point; since it's still in the manual but I never saw it.

Hello,

when your camera is in perspective projection mode, the zoom speed (with the mouse wheel) depends on the distance between near and far clipping planes. So if you adjust those values, you achieve also faster or slower zoom. This is to automatically adjust for very large scenes, or small scenes (given that you have correctly adjusted your camera).

The fly button was removed since it was more of a gimmick, and something similar can be achieved via a customization script for instance.

Cheers
