Assembling panoramas by simply overlaying them in a graphics program will usually not give good results, because of the perspective transformations that occur when a camera is rotated.

Further, every real life lens has a certain amount of distortion (barrel distortion or pincussion which will worsen the stitching results even further.

Panorama Tools solves this by warping the images and correcting for lens distortion. The images are positioned in 3D space, so that they match as best as possible.

Features of PTGui:

• Create spherical, cylindrical or flat panoramas from any number of source images
• Supports JPeg, Tiff, Png and Bmp source images
• Panorama editor for visual and interactive parameter editing
• Photo stitching
• Multi-threaded design: all image processing is performed in the background
• Create templates with frequently used settings
• Lens database for easy retrieval of lens parameters
