CleVR look around...

On Monday, Adobe AIR was officially launched. Of course, we’ve been using the beta version of AIR for the CleVR Stitcher for over six months now, but it’s good to see it go 1.0. This means that we’ve also released a new version of the Stitcher, which uses the latest version of AIR. You can install it below, using the shiny new installer badge. It will update or install AIR for you if needed.

All of the panoramas on CleVR, as well as swfs and thumbnails are hosted on Amazon’s Simple Storage Service (S3). This has always been very reliable for us, but today they’ve been having a major outage. Currently it has been down for around 90 minutes, and they’re not giving an estimate of when it will be fixed. We have moved everything to our other servers, so things should be working fine. However, some people may experience issues where the old DNS information has been cached by their servers. Please bear with us, and it should update within an hour or so. Of course, if Amazon fix it then it will start working before that.

For those who are interested, the status information from Amazon can be found here.

If this image works, then Amazon s3 is working again:

Update 1510 UTC: Seems it’s all up again now. We’ll switch back to S3 in a bit when we can be confident it’s staying up.

I’ve just uploaded the first in a series of screencasts showing how to do various things with CleVR. The first one is about using the Stitcher, and you’ll find it below the cut. Let me know what you think, and what things you’d like to see in future tutorials.

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.

The site has been hard to reach for the past few hours, due to our DNS provider being hopeless. We’ve moved onto another nameserver as a temporary measure, and will be transitioning to a more reliable provider ASAP. We apologise for any inconvenience.

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!

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.
