Controlling pano from another window

Hi,

it's an interesting fact that you can control your pano from another window. That of course requires that you are in an environment where you can show more that one window.



I made this little "remote controller" as a test.

Hi Jordi,

I gave it some thought earlier, but I'm not an expert at these things. As long as you keep your communication inside the browser, you can use the DOM (or BOM) tree.

But I think as soon as you want to communicate outside the browser, you have to use something like a Web socket. However, these communicate with an URL, so you probably have to go through a web server application - or maybe something like how Internet gaming works.

So if I understand that correctly, we could establish a JS-connection between two krpano-instances via websocket?! One instance would send the js-commands to the node.js-server and the other instance receives these commands, just like it does in Tommys example? And just like a simple chat-system the node.js-server could even be used for a two way-communication where the second krpano-instance returns permanently the actual scene-status like ath, atv and fov? *blink*

Yes, the two (or several) instances would open a websocket connection to the server application, which only acts as a transfer node between the instances. If all of them are krpano instances, I guess it would be wiser if one is the master and the other slaves - at least if you want to coordinate pano movement.

And you would probably prefer to have an Apache module in your webserver to get quick response, but my own homepage is in a web-hotel, so I don't have that possibility. On the other hand, I run an Apache server in my home PC, but I have forgotten how to write an Apache module.

In the meantime, I made another test page, where you can see that it's possible to control two separate panos with the same remote control:

Great example, Tommy...again *thumbsup*
Would it be possible within your example to control the second pano not with the tool but the ath, atv and fov-values from the first pano?

We really need an websocket/Apache-expert here! This is just to darn good not to be done *g*

You can of course always trap all movements in the first pano with the "onviewchange" event, and then send it with javascript to the second pano. But I can't find any way to stop all mouse or keyboard input for moving the second pano directly. I thought I could do it when I found the stopmovements() command, but this only interrupts already ongoing movements. Maybe you can place a transparent <div> over the pano window to prevent any mouse action.

Just putting a transparent layer above all in the 2nd krpano-instance would be my first choice, because it´s simple and effective! And with the zorder it´s even possible to put some buttons in top of that, to activate or deactivate direct user input. That´s how I de- and reactivate all user inputs after starting the "Autotour" in my virtual tours.
