Google Maps Javascript API / Streetview FOV

Question

I was wondering if there was any way to change the field of view of a StreetviewPanorama object?

This is not documented anywhere but the Google Maps website does not see

Answer 1

I have a same problem like this. Did you use Firefox too?

When I'm using Google Maps API on Chrome it's totally the same as the Google Maps. Still can't find a way to solve it.

The fov should be the same as they mentioned in the documents.

https://developers.google.com/maps/documentation/javascript/streetview

So the problem will be the projection they used.

I just tried to change the user agent to cheating the API that I'm using chrome. And it works.

navigator.__defineGetter__('userAgent', function(){
    return 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.153 Safari/537.36' // customized user agent
});

But it turns out very slow when I try to drag the panorama.

Maybe that's why they're using a big flat image instead of a 3D spherical one.

Good news to solve this problem.

I found a solution here in Google Groups.

There's a undocumented attribute "mode" can be set in PanoramaOptions.

You can use 'html4', 'html5' and 'webgl'.

It will be no fish-eye effect if I set the mode to 'html5'.(But tourdash use 'webgl' instead)

The following shows the code snippet:

var panoramaOptions = {
        pano : panoId,
        pov: {
          heading: heading,
          pitch: pitch
        },
        enableCloseButton:false,
        addressControl:false,
        panControl:false,
        visible: true,
        clickToGo:false,
        addressControl:false,
        mode : "html5",
        zoomControlOptions:{
            position : google.maps.ControlPosition.TOP_LEFT
        }
    };

It works way much better than just set the user agent.
