A question on field of view
 
Hi I am working on something that needs to change the field of view of the HMD.
Is there any difference if use viz.fov or viz.Mainwindow.fov functions?

The other question is that: when I use viz.fov() and viz.Mainwindow.fov() functions, it seems that these two functions both change the view distances to achieve the goal of changing the view, because when I reduce the FOV, the object in the screen became bigger, which means that the distance is smaller.
Is there anyway that not change the distance of the view and keep the object the same size, then just see less things in the environment?

Thanks.
Qiufeng
