3DVista Stitcher vs PtgUI

3DVista Stitcher 4 turns groups of photographs into panoramas through a guided, one-click workflow. It accepts standard, wide-angle, fisheye, and one-shot lenses and most popular camera types. Outputs can be full or partial panoramas in cubic, spherical, or small-planet forms, with 18 projection types including equirectangular, rectilinear, cylindrical, and small-planet. Automatic control-point detection helps align images, and you can add, move, change, or delete those points. One-click standard HDR and Adaptive HDR stitching are included, as is batch stitching for multiple panoramas. Stitcher can process 3DVista Live Panoramas and Adaptive HDR Panoramas; publishing those as immersive virtual tours requires Virtual Tour Pro. The software runs on macOS and Windows, supports HDR blending and control-point editing, and does not support RAW input. A free trial is available.
