It's very simple:
Unzip the content of the packages into the "\pano\"-folder of your current version of JONGL.
That's it!

Most of the panoramas in these files are projected on a cylinder. This gives very good results for a horizontal ground and for example an inner courtyard. Not every environment has this favorable property. So the illusion of an wide landscape is only given for a certain point of view.
Don't be disappointed, it would be too much work modelling every landscape.
It may take a while to load the panoramas in JONGL, so I have created two versions, a small one for slow computers/downloads and a big one for those who want to enjoy the full resolution.
