Did you post a test blogpost so we can take a peek at it? Otherwise, there are (free) products on the market to reduce/obfuscate javascript code, for instance JSMin [1], YUI Compressor [2] and Dojo Compressor [3]. This might help fit the javascript code into the blog. I don't know what exact restrictions apply, so I cannot guarantee this will work.

The html and javascript files were successfully combined and tested locally. http://sabahheaven.blogspot.com/ When exported to blogspot, I had to remove html headers, but actually blogspot will remove headers for you automatically. headers such as body, html I use blogspot the most because it is the most stable among my sites but friends don't appreciate the 2D picture representation of a 360 degree panorama because of the distortions. I need to get a pano viewer for blogspot. Your javascript is the most ideal, if only I can make it to work. Thank you so much for the tips. I was not aware of them before. I had to delete comments manually. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.

[hugin-ptx] Re: Pure JavaScript pano viewer
I had tested it locally. It worked but my main aim for a javascript based viewer is to use it for blogspot. I tried but failed. Somehow blogspot blocks some scripts. Initially the script is too large so I deleted all comments so that all scripts and forms were not corrupted but it still does not work. I had deleted some headers. Maybe that could be the reason. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.

Too bad, Exactly my thought. I really like the Javascript viewer, even though I would prefer if the mouse controls would be like traditional VR viewers (inverted left and right). I gave that one a thought, but decided somehow that inverted left and right belong to viewers which also implement autoscroll. I'll add it as an option (which is really too easy), because the idea attracts me as well. Autoscroll can be added fairly easily as well, although it's probably useless when the speed is only 3 fps.

[hugin-ptx] Re: Pure JavaScript pano viewer
I don't mind hosting. Great! What type of traffic can we expect? Very little. It's only the html and js that have to be hosted, the images can be hosted anywhere. The example html uses one picture directly from my Picasa photo album and two other images I found using Google. I´m a bit busy right now, but when I get more time, I´ll update the html and js so parameters (like hFovDst and mode) can be tweaked more easily. Tweaking is already possible, but at the moment a call to setMode is needed to propagate the changes to the individual div elements.

[hugin-ptx] Re: Pure JavaScript pano viewer
Bart This is an excellent piece of Javascript coding.. I have tried using the script on my website, rather than hosting the demo examples; see http://www.miltonpanoramic.co.uk/javascriptviewer.php . From my initial experiments the examples you gave were just too slow (10seconds redraw) so I decided to scale the image down to get a faster movement.. However now trying the http://www.tatteredmoons.org/jspanoviewer.html with FireFox I find I can view the Trucks in Car-Park pano as fast and smooth as any flash / java plugin I've used.. It seems that Internet Explorer is much slower.. At Home and at Work, with IE7 the redraw is just too slow, 5s and 10s respectively At Work with FireFox 2, the redraw is lightning fast. What are other people finding? Given this I think I will try using the script on fullsize panoramas on my website, then testing in other browsers.

[hugin-ptx] Re: Pure JavaScript pano viewer
Hey Bart Over the past two weeks, I've built a panorama viewer using only standard html and javascript. It expects full or partial cylindrical/ equirectilinear panoramas. The renderer works with div elements containing vertical slices of the input image, so fisheye type panoramas cannot be displayed. Maybe a future version using a canvas could overcome this limitation (and add some speed...) That looks impressive, great work. If someone could host a demo (the unpacked version of the archive, optionally beautified a bit with some style rules), please let me know, so I can link to it from the project home page! Maybe we could feature it on the Hugin home page? I've downloaded the code, fiddled a bit with the html (mostly to make sure the panorama is always in the middle of the window, no matter how you resize it) and uploaded an example here: http://habi.gna.ch/jspanoviewer/ I've also added two more presets to the list :) Will keep a close eye on this!

[hugin-ptx] Re: Pure JavaScript pano viewer
Hi all, Great to see that I'm not the only one who likes the idea of a javascript panorama viewer :) Regarding speed, I've been fiddling around a bit myself with the current version, and here are some of my (mostly quite obvious) findings: - Smaller dimension of input image: faster - Smaller dimension of panorama viewer: faster - Less vertical slices (larger wSlice): faster (but less accurate) - Smaller visible part of the input image (smaller vertical field of view): faster. Compare MODE_PRESSx to MODE_NORMAL or MODE_PANNINI for example. - Google Chrome or Firefox versus Internet Explorer: faster. I've tested the script on my new laptop (Core2 Duo at 2.23 GHz), my 4 year old desktop (Athlon64 at 2.2 GHz) and a pretty recent computer at my job, with the current html file (720x300 pixels). It doesn't run nearly as smooth as most Flash viewers, but 1 or 2 frames per second using IE, and a little more using Chrome and Firefox. Considering it's just Javascript, I found this pretty okay. But of course I hope to get newer versions to run faster. It's open source, so others are of course welcome to contribute.

Now that I'm home I've also tested it on OS X (10.5.6, on a MacBok Pro with 2GB RAM @ 2.33 GHz). With both Safari (3.2.1) and Firefox (3.0.8) the script works fine if the images are not too big. The preset Twin Lakes is slow (less than 1frame/sec), my presets with the Baldachin (on http://habi.gna.ch/jspanoviewer/) work quite well, nearly realtime. just my 0.02$, have a nice evening. habi --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.
