I have written a program that contains a model of a 3D environment and now I would like to make a "VR Tour" of my computer's little world using KRPano. I want the program to output something that KRPano (the multirestool in particular) would expect as input but what projection I should use? I'm aware that one can specify the projection as e.g. cylindrical or spherical but I don't know what type of cylindrical (equirectangular?) or spherical (mercator?) KRPano expects.
Can someone tell me what my options are please? You may assume I know how to map a view of a 3D scene onto a sphere that is centred on the viewer's eye.
Thanks,
A
