A technique for capturing and viewing “Gigapixel images” was described at the recent Siggraph 2007 Conference and exhibition. Gigapixel images are very high resolution, high dynamic range, and wide angle imagery consisting of several billion pixels each

Here are 3 views from a gigapixel image:

In order to view Gigapixel images you need HD View.

HD View is a new viewer developed by Microsoft Research’s Interactive Visual Media group to aid in the display and interaction with very large images.

HD View was developed with a number of goals in mind. It should:

• allow smooth panning and zooming on large images,
• only download enough data to create the current view (and possibly look ahead to the next),
• always display the current field of view with an appropriate projection. This means that when zoomed way in you should be presented with a standard perspective projection providing a sense of immersion, and when zoomed out you experience a curved projection so that get a full overview of the scene. In between the projection should smoothly transition.
• Finally, it should be easy to create your own HD View content and present it to the world via the web.
