How do you reload a tour to its initial state without reloading the HTML page?

Quoted from "indexofrefraction"

what is the problem with a reload?

Nothing crucial. The extra time of loading the HTML page. The visually jarring loss of all the HTML elements before redrawing the page.

At the moment I'm developing a headset interface for a tourist center. When one person is done I want the tour to automatically reset to its initial state for the next user. For instance, taking off a GearVR headset causes it to jump out of VR (using a web browser). I can use the onexitvr event to reset the tour. However, it doesn't actually execute until the next person puts on the headset. If I do a page reload using location.reload(), you first see the pano last viewed by the previous user, then everything goes to black and reloads. Tolerable but not elegant. If I could simply do something like loadxml(tour.xml); -- which doesn't work -- it might be more elegant. So looks like reloading the initial scene and explicitly resetting everything is the way to go. A bit more work but nothing too taxing.

It has been proving problematic. In Gear VR and GO the tour drops out of VR shortly after taking off the headset. I use a custom splash screen to start VR and being a layer it disappears in VR but shows when you drop out of VR. On the Go I just click it and reenter VR. On Gear VR I have to hit it at least twice and sometimes only a page reload works. I've used both the webvr_onexitvr event and the button click to do the start scene reload and reinitialize certain variables. Still nothing perfect.

Ah, the joys of programming...
