krpano HTML5 Multiresolution Support

krpano 1.17 is the first version with HTML5 Multiresolution support. View the demonstration examples here or download and try the new viewer with your own panoramic images.


The new krpano HTML5 viewer offers high-performance and high-quality pano rendering and can easily handle any kind of panoramic-image size - from several Gigapixel up to Tera- or even Petapixel (1 Petapixel = 1 Million Gigapixel). Therefore here some examples to demonstrate the performance and the display quality of the new krpano HTML5 viewer.

First here an extremely large full-spherical pano - it is rich in details and invites you to explore it:

300.000 x 150.000 Pixel

The tiles in this example were generated dynamically on-the-fly on the server.
