I’ve just pushed out an update to the site, which adds a few things. The real biggie is commenting on panoramas. Yes, you asked for it and you got it. (Well, maybe you didn’t ask for it, but others did). It’s pretty simple. There’s a box on each panorama page where logged-in users can add comments. You can delete your own comments or those on your panoramas. If you’ve enabled email notifications, you’ll get one when someone comments on your panorama. Let me know if you find any problems or have any comments, or just add a comment below.

There are a few other smaller changes. One of these is the single most requested feature – a link to view the full size panorama image. This is displayed on your own panoramas. If you click on it, then you can then save or print the full size image. Enjoy!

Earlier today, new panorama uploads were not working. This is now fixed. Sorry for the inconvenience!

The hotspot editor on CleVR.com has now been updated so it’s the same as the one in the new Stitcher. It looks quite similar to the old one, but it’s a rewrite done in Flex instead of Flash (if you don’t know what that means, don’t worry). It is however pretty much bug-free now: the old one could be a bit unstable at times. Now that it’s running off the same codebase as the Stitcher, any remaining bugs should be fixed quickly. As ever, comments and bug reports are appreciated.

If you haven’t tried adding hotspots to your panorama, give it a try. If you’re logged-in, you’ll find a button on the panorama page to edit them. Hotspots let you add another level of interactivity to your panoramas. You can create areas within the panorama that can be clicked to give more information or to move to another location. You can display text, images or even Flash files such as Youtube movies. Links to other locations lets you move around an area – for example, you could click on a doorway to move to a panorama inside a building or in a different room.

I’ve put up the CleVR AS3 libraries on RIAForge, where you can download them as a zip file, or use the svn repository.

The library includes a number of classes that we developed as part of the CleVR Stitcher. They include a set of matrix algebra classes, ported from the Java JAMA library. These let you do standard matrix algebra stuff, and includes support for singular value decomposition and QR decomposition.

There’s also some graphics classes. One is a subclass of BitmapData that adds bicubic and bilinear interpolation. Another is a class for calculating the histogram of an image, with methods to do histogram stretching. This gives results similar to “Auto levels” in Photoshop, or “Enhance” in iPhoto.

You will find them here. They’re released under the Creative Commons attribution licence, which basically lets you do anything with them, so long as you give credit somewhere. A link to clevr.com would usually suffice. Let me know if you have any comments, patches, or if you’re using it.

I’ve just pushed out an update to the CleVR Stitcher which is probably the biggest improvement yet. Loads more features, loads of bugs fixed and a much nicer interface. You will find all the details here: CleVR panoramic photo Stitcher. As always, it’s totally free. Let me know what you think.

I decided to enter it into the Adobe AIR Developer Derby. It’s hard to judge its chances, but I’d love to win that squishy stress ball. If they’re going on innovation, I’d say they’d be hard-pressed to find an AIR app that is pushing the boundaries more than this. In terms of using AIR technologies, we’re using almost all of them! We’ll wait and see…
