Google Street View Panorama Util

GSVPano.js - Google Street View Panorama lib

Library to help requesting and stitching Google Street View panoramas.

Where is it then?

Sadly, I've been requested by the Maps team to remove the library, since it was enabling people to break Google's Terms of Service. Which is true, but also an intrinsic problem with the only purpose of the library. Let's hope in a very near future the Google Maps API will provide a very similar feature.

gsvpano.js's Issues

Out of sync pano reload issue

I've noticed that when you update the pano location in quick succession (i.e. anything which results in two composePanorama() calls before the first one completes) the images from the first one can overwrite the second one, causing a nasty shearing effect between the two locations.

The fix is simple: just add a request number to each pano, so that we can drop ones which are not relevant any more.

Variables:

_requestNumber = 0,

In the lamda for compsePanorama:

                (function (x, y, iRequest) { 
                    var img = new Image();
                    img.requestNum = iRequest;
                    img.addEventListener('load', function () {
                        self.composeFromTile(x, y, this);
                    });
                    img.crossOrigin = '';
                    img.src = url;  
                })(x, y, _requestNumber);

At the top of composeFromTile:

        // Do we need to drop this request (i.e. it is for an old pano).
        if (texture.requestNum != _requestNumber)
        {
            console.log("(EE) Pano image request number out of sync.  Dropping draw request.");
            return;
        }

Impressive library, thanks for sharing. 👍

Error loading handling

Had some troubles yesterday with fault urls when loading panos that causes the load-complete callback to fail. Thought it was a quota-problem but it was the _count that did not get updated when a pano failed to load. I don't know why it wasn't a problem before. Maybe it's some changes with the response on faulty requests. In my examples I added a onerror event that increase the _count and also checked if it was the last one. Thought you might want to know the demos are broken even though this repo is empty.

Error creating WebGL context.

Hey - I've downloaded and tried to run locally your examples, and I get an "Error creating WebGL context." The same thing happens in your online example. I'm using Chrome Canary on Mac 10.7.5 - is there an error with the code or maybe something in my system? I feel like I saw this example working at some point recently.

Fix please

All panoramas not showing on map.

researching Web VR/360 viewer, sadly this one is gone :(

Flipped panoramas

Great tool!

I've been trying to figure this out: why are the returned panoramas sometimes flipped?
