History

CleVR was originally launched by Clementine in 2000 as a platform for managing

public beta

as a free site that allowed panoramas to be created by anyone. Much of the content from the previous CleVR site was imported to the new platform. The new site was a complete rewrite of the old code, and was no longer based on QuickTime VR. Instead it used a Flash viewer developed by Clementine to display the panoramas. The new site was officially launched in April 2007.

On the current site, the photo stitcher and panorama viewer were developed using

Flex and AIR. The CleVR site is written in PHP, and uses PEAR and ImageMagick. Images are hosted using Amazon S3

.

Photo stitcher

CleVR includes free

projection

supported by the CleVR website and software. The stitcher has fewer features than other image stitching software, but is designed to be simple and easy to use.

The CleVR photo stitching software can stitch most panoramas without user interaction, but also has support for setting manual control points. While the finished panoramas can be saved to the user's computer as a JPEG file, in most cases they will be uploaded to the CleVR website from within the stitcher.

Users can also use other stitching software to create panoramas and upload them to CleVR.

Panorama viewer

The most distinguishing feature of CleVR is the way it allows panoramas to be easily shared and posted on other sites. This is done in a manner similar to services such as YouTube, using a Flash-based viewer that can be embedded in a web page or viewed on the CleVR site.

The viewer re-projects the equirectangular panorama to an orthographic projection so that the view appears more natural, without the curved lines otherwise typical for panoramic photographs. It also overlays the clickable hotspots for navigation and the display of text, images and video.
