unload scene

I plan the following scenario of panaroma user interact:

1. loading pano
2. navigating (changing view)
3. loading scene
4. maybe loading second scene...
5. return to the pano that was left in the point of 2.


The view that was left before loading scene should not be changed.


So i cannot resolve the point of 2: how to return to the pano and view that were left before loading scenes.
Any ideas?


Thank you

You can save each hlookat, vlookat, fov, ... values before leaving a scene into an array linked to the scene name and use these values if exists when you go back to the scene.

Example : usage of arrays into the webvr.xml file.

Thank you for your advise, benji33. I have implemented the way of saving view variables and restoring them after all.
