is it possible to implement custom projections for the cameras in order to produce different form of panoramas?
It is currently not possible to implement a custom projection, Kit does not offer an API or extensions for this. Some features to natively render fisheye lenses will be made available in a future release.
If I can ask, what type of panoramic projection do you need?
I see, thanx for the info. The same kind of projections as is used as the skymaps for the doom-lights would be nice. Especially if the horizontal and vertical angular ranges could be specified separately. Also, stereographic projections are of interest.
