After several months of beta testing PTGui 10 is now officially released!
The most important change is entirely under the hood and has been under development for over two years: PTGui 10 features a new stitching engine, rebuilt from scratch to get the best peformance on modern hardware. On computers with a recent graphics card (GPU) the new stitcher uses OpenCL for GPU acceleration, but regular CPU stitching performance has been significantly improved as well. For certain projects we've seen up to 10 times faster stitching compared to the previous version!
To complement the Publish to Website tool, PTGui 10 includes a spherical panorama viewer for local viewing. Spherical panoramas can now be viewed from PTGui without the need to install third party software. The viewer is a standalone tool: it can view any equirectangular panorama in TIFF or JPEG format stored on your computer.
Finally the Pro version includes a new tone mapper. The new tone mapper is easy to configure and gives very natural looking results. The tone mapper can now be enabled even for non-HDR panoramas, improving the quality of panoramas of high contrast scenes.
