Change mouse wheel zoom speed for ArcRotateCamera

[Vousk-prod.]

Heyo guys,

 

For my scene the speed is really too fast when scrolling mouse wheel.

Is there a variable we can set to change the zoom factor ?

 

 It seems in babylon.arcRotateCamera.js that the only used factor is hardcoded value "120"

            this._wheel = function (event) {                var delta = 0;                if (event.wheelDelta) {                    delta = event.wheelDelta / 120;                } else if (event.detail) {                    delta = -event.detail / 3;                }                if (delta)                    that.inertialRadiusOffset += delta;                if (event.preventDefault) {                    if (!noPreventDefault) {                        event.preventDefault();                    }                }            };

but maybe I misunderstand something (and I don't know what delta = -event.detail / 3; is about)...

This is clearly a missing feature

 

event.wheelDelta is for IE and Chrome

event.detail is for Firefox ( which do not use same ratio)

 

I've added a new parameter to arcRotateCamera:

wheelPrecision

Hi, using 3.0 alpha in chrome, trying to tame the zoom factor / speed but i can't really get any effect with arcRotateCamera, I am trying to have a slower mosue wheel zoom as all my world is in a-1,1 range for all coordinates. Any suggestion?
