I thought to use a view where the projection axis remains in the center of the display.

The diference, particularly if closed up, wouldn't be too great. Probably the rectilinear projection would be most familiar, and look most like what most users input. I was just thinking of making it computationally efficient and thought equirectangular would be the most efficient one.

I must have failed to see this because I mainly do landscapes. Kay -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
