If you are talking about an
object 360 photography that is not for be processed with PTGui. No way to stitch the images in a single image.
You can be interested in softwares like Pano2vr or KRPano. You don't need to stitch images, those software keeps on the fly the necessary
image to display it. 24 images for a single row object is the minimum, more shots you add more fluid will be the movement of the object.
