How to change Field of View in Google VR SDK for Unity

问题

I created a AR stuff with Google VR SDK for Unity and NyARToolkit (http://nyatla.jp/nyartoolkit/wp/?page_id=198).

Current AR screen of application, however, is not fullscreen. I wanted to change Field of View of "Camera Left" and "Camera Right", but these didn't effect on screen. How should I change to fullscreen?

回答1:

To change the Field Of View of Google VR SDK, folow these steps :

1) First select the Main Camera in GVR Main

2) Make changes to Stereo Controller Script from Inspector (Change values of Match Mono FOV & Match By Zoom according to your requirements)

3) Now run scene and change Field Of View value of Main Camera, and you will see effect on screen.

Hope this will help. Thanks.

I used Legacy/Prefabs/GvrHead. I set "Match Mono FOV" to 1 and "Match By Zoom" to 1 in Stereo Controller option. It works well.

Also ran into this problem weeks ago. Sometimes, you have to modify the stereoMultiplier too. Here is a simple function I use to fix this problem:

void fixFieldOfView(float stereoMultiplier = 1, float zoom = 0f, float fov = 0f)
{
    StereoController stereoCtrl = GvrViewer.Controller;
    stereoCtrl.stereoMultiplier = stereoMultiplier;
    stereoCtrl.matchByZoom = zoom;
    stereoCtrl.matchMonoFOV = fov;
}

Usage:

fixFieldOfView(1, 1, 1);
