Hi guys,
Is camera zoom going to be implemented in away3d v4?

You can achieve zoom by using the fieldOfView property of the camera’s lens.

Thanks John,
I’m porting an away v3.6 application to away v4. It has to load the old version settings for zoom, etc., so I need to convert the old 3.6 zoom settings to the new version.

Update: I have found this formula, but it doesn’t seems to work for me:

fieldOfView = 2 * arctan(ratio / zoom)
where ratio is ImageWidth / ImageHeight
