PTGui is panoramic stitching software for Windows and Mac OSX. Originally developed as a Graphical User Interface for Panorama Tools (hence the name), PTGui now is a full featured photo stitching application.

New extremely fast stitching engine with GPU acceleration, included spherical panorama viewer, improved tone mapper, more..

Use PTGui to stitch any number of photos into a panoramic image. Some benefits of PTGui, when compared to other stitching software:

* PTGui can stitch multiple rows of images
* Blazing fast stitching engine with GPU acceleration via OpenCL
* Create 360 degree cylindrical panoramas, 'flat' partial panoramas and even spherical 360x180 degree panoramas
* No need to keep the camera level: PTGui can stitch rotated and tilted images
* Virtually unlimited output size: create gigapixel panoramas from hundreds or even thousands of images!
* Masking tool (PTGui Pro) allows full control over the final stitched result
* PTGui stitches most panoramas fully automatically, but at the same time provides full manual control over every single parameter. This enables stitching of 'difficult' scenes, where other programs fail.
* High quality interpolators for crisp image quality
* HDR support, exposure fusion and tone mapping build in (PTGui Pro)
* Included spherical panorama viewer and web publishing tool
* Batch Builder: scan folders for panoramic images and stitch them automatically
