I'm written the plugin on ActionScript3.0 and I need to receive the screen coordinates of points of hotspot. But there is only function "screento sphere" in interface krpano.
I have the same problem in my plugin! I'm writing plugin like "Editor plugin" and I need to edit loaded from krpano hotspots. As I know krpano has only screentosphere function and hasn't spheretoscreen function. For this reason I can't load hotspots from krpano to show on screen and edit. I had tried to find some formulas to calculate sphere coordinates to screen manually, but found only "screen to sphere" formula here http://www.experts-exchange.com/Programming/Ga…Q_21869528.html. I had tested this formula. It works, but not exactly. The errors are the tenth shares or whole units of spherical coordinates. Now I'm trying to calculate "sphere to screen" formula but has no any satisfying results yet.
