optimizer independent from projection types

[Michał Kaczmarczyk]

IMHO the optimizer should use spherical coordinates and minimize angles, instead of minimizing pixels on projected plane.
In such a case the optimizer:
- will not prefer areas where projection distortions are large (a minimal angle error in such areas can lead currently to a large pixel distance, which has greater impact on the optimizer),
- will provide consistent results, independent from selected projection type and image size.

I agree.

The design of libpano is so that the line control points are calculated in the output projections. So we can't change this with breaking all current and older projects.

You mean vertical and horizontal lines?
They could align to meridians and parallels of the sphere.
