We’ve just released a new version of the CleVR Stitcher. This uses the new version of Adobe AIR, and also adds several features and fixes lots of bugs. If you download it, please do let me know what you think and if you have any problems with it.

Yup, another update to CleVR. Firstly, the AIR CleVR Stitcher has been updated again. We’ve also made it the primary Stitcher now. The Java version is still available, but we recommend everyone move to the AIR one now, as it’s a lot better. This version runs on Beta 2 of AIR, just released by Adobe. If you launch it from the stitcher page and you’ve previously run the AIR Stitcher it will update your version of AIR automatically. The Stitcher has few updates from the last version, probably the most significant of which is a greatly improved uploading system. It’s a lot quicker.

Secondly, updates to CleVR.com. Following on from commenting, added at the weekend, we now have tagging. So Web 2.0! You can add tags to your panoramas, such as place names and so forth. Give it a go: you’ve find the button for it on your panorama pages if you’re logged-in.

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!

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 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…

Yesterday’s update to the CleVR Stitcher has a number of new features. One of these is image enhancement for the finished panorama. This corrects under- or over-exposed images, and works in a similar way to “Auto levels” in Photoshop, or Enhance in iPhoto. See below for more details and a demo.

For the second release of utility code from CleVR Stitcher, the Adobe AIR panoramic photo stitcher, I’m offering our InterpolatedBitmapData class.
The class adds support for bicubic and bilinear interpolation to the Actionscript BitmapData class. It adds two public methods - getPixelBilinear and getPixelBicubic. You can call these with sub-pixel coordinates and it will interpolate the RGB value for that point. This should be useful for anyone doing more complex transformations than those offered by the Matrix class. I hope it will be useful to someone. Do let me know if you’re using it. As ever, a link back to clevr.com is appreciated but not required.

Download it as part of the CleVR Actionscript Library

The Stitcher is the oldest part of CleVR, originally developed nearly four years ago, so it’s needing an upgrade. It was developed in Java, delivered by Web Start, a system that I’ve never been happy with. I decided that the best plan for the new version was to rewrite it from scratch. It’s a Flex-based Adobe AIR app. AIR, formerly called Apollo, is a new cross-platform runtime under development by Adobe. The first beta was released earlier this month, and it’s a joy to develop for. I’m pleased to announce the first alpha version of the new AIR-based CleVR Stitcher. You’ll need a CleVR account to use it. It’s free, and only takes a couple of minutes to sign up.

The choice for the development platform will be surprising to many people. The idea of doing computer vision and image processing in Flash sounds like madness, but the advances in Flash Player 9 make it possible. While developing the CleVR panorama viewer, it became apparent to me quite how powerful some of the new features were, and the performance improvements in the new Player have made it feasible. The current version is slower than the Java stitcher, but there’s a lot more optimisation that I can do, and it’s certainly usable.

Currently it’s missing a number of features from the Java version, most importantly the ability to repair failed stitches. However, I’ve made several improvements to the algorithms, so there should be fewer failed stitches. The repair facility will be added in a future release, as will several other useful features.

Give it a try, and let me know of any bugs that you find, and any other comments that you have.

A few minutes ago, we reached a small milestone: our 1000th panorama, and it’s a beaut. See it below. We’ll soon be on our thousandth user too, which is nice. We have some big news coming up over the next week, so stay tuned.

A couple of less positive things: we appear to have a bug in the stitcher which is causing problems for Mac users with PowerPC. Intel-based Macs seem to be unaffected, as does Windows. This seems to have crept in when we updated our code-signing certificates a few days ago. We’re working on it and hope to have a solution soon.

Update: The PowerPC problem is now fixed. G3, G4 and G5 users rejoice!

Likewise, there is a problem with signups for users with Yahoo email addresses. The Yahoo servers don’t seem to be playing nicely with our password emails, with a lot of them still trying to be delivered. We’re in contact with Yahoo and trying to get it resolved. In the meantime, either try to sign up with a different address, or if you use a Yahoo address and you don’t receive a mail, contact us with the username and email that you used to sign up and we’ll sort it out for you.

Via 37signals SVN, I ran across this pdf book of Lessons In Virtual Tour Photography. It has to be the strangest take on the subject that I’ve seen. It’s obviously meant as a wry look at the world of real estate photography, but I don’t know if I could call it that funny, just, well..weird. But amusing enough to take a look. Beware naughty words.
