The basic idea is to have 2 screens installed in front of each other to display "front" and "back" of the panorama at the same time...
I thought I could try to use the syncscreen example
<events onmousedown="set(syncother,true); events.onviewchange();"
onmousewheel="events.onmousedown();"
onnewscene="set(syncother,true); events.onviewchange();"
onviewchange="if(syncother, js( sync_1to2() ) );"
/>
krpano2.set("view.hlookat", krpano1.get("view.hlookat"));
krpano2.set("view.vlookat", krpano1.get("view.vlookat"));
krpano2.set("view.fov", krpano1.get("view.fov"));
krpano2.set("scene.name", krpano1.get("scene.name")); //krpano2.loadscene( "scene.name");
Thanx !
