Actually I know that telling hugin how many rows there are is useless as well - at least for my projects. But I don't claim that the universe of possible uses is limited to my projects and if people have done the "measurements" to determine that telling hugin how many rows there are is useful for them, why should I stand in their way? > You could base an "initial preview" on this information, but hopefully > we'll be able to do that without this info anyway. Actually there is one much more important thing that can and should be based on this information: optimization. It happened to me many times in the past that when I optimized a project from an all images at 0,0 position the optimizer fell into a local minima and the result was useless. On the other hand, with the images distributed approximately, the optimizer never failed me. > Why do people think it's useful? Because they think [...] from experiences like mine above. It was in my intense spherical shooting days. I was shooting three or six around with a modified/tilted pano head [0]. Just distributing the input images blindly along the horizon made a different between a bad optimization and a successful one. It may be a relic of the past, and the tools are now more robust than ever, and the "grid" may not be necessary anymore. But it has other advantages that will never go away, such as visual inspection of the input images before they are fed to the CP generator and to the optimizer, to make sure there are no duplicate images, redundant images of some sort, missing images, etc. All of this would be part of the Images Browser (or Images Tab), and completely optional.
