Is there a way to control the zoom increments on a perspective camera? in other words to increase the number of divisions between the min and max zoom??

```
app.controls.zoomSpeed = 2.0;
app.controls.zoomSpeedTouch = 1.0;
app.controls.zoomInertia = 0.15;
app.controls.zoomInertiaTouch = 0.05;
```
btw, in Firefox zooming works twice slower than in Chrome.

Puzzles and JS coding. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

Thanks for the info!
These parameters have an effect indeed, but that’s not really what I was looking for.
My issue is that it looks like there is a constant number of zoom steps, whatever the distance between MinZoom and MaxZoom is, meaning that for small distance, controlling the zoom level is easier than for big distances where one mouse wheel step equals to a much greater distance. My question was: is there a way to increase the number of zoom steps depending on the MinZoom/MaxZoom distance??
Thanks for the help!

Such a parameter doesn’t exist. Dollying (zooming) delta per one wheel move is directly proportional to the distance from the scene’s camera to its orbit center. The farther, the more.
