Do you have an idea for an awesome feature we should add… or hate the way we’re currently doing something? Share your ideas and suggestions here.
My Photosynth shows many objects in a scene. I’d like to be able to enter the Photosynth on a close-up of any one of the objects, ie I’d like each object to have its own URL to start the view.
The location is (sorry if you find this morbid) a graveyard, and I’d like to use the Photosynth to support a web page that allows visitors to look up an ancestor’s name in an index and link to a view of their gravestone. They may then zoom out and move around to get a feel for the surroundings.
I’ve been testing the approach at http://photosynth.net/view.aspx?cid=8dbddfee-1b58-42f7-acea-65280c7a0884. This Photosynth starts on one of the gravestones, but I’d like to have an alternative URL that starts the view at the gravestone next to it.
Or perhaps someone can think of another way to achieve the same end?
Sorry - my URL got a period stuck on the end, so takes you to the "This Photosynth has been deleted" page. This should work:
Have you tried modifying the "Starting Image"? ("Edit this Photosynth" button on that view page)
@Adrian, the 'Starting Image' is only good for one entering point per synth and what Timjh is needing is multiple different entryways into a single synth.
@Timjh, actually the Photosynth website has supported exactly what you're asking for since the first day that the public could upload our own photos.
The answer is the 'Share' links. Any time that you click 'Share' on the site and get a URL, you get the default URL to your synth or pano, but then get additional image number, zoom level, and camera coordinate data added onto the end so that if you send the link to someone, they'll see just what you did when you generated the link.
The exceptions to this are if you are in Overhead View, or 2D/Grid View.
Since your synth is a small one, I'll post a couple of example links to show you what the different parts of the Share links do.
Nathanael, thank you SO much! I hadn't spotted the Share button. I'd looked through the forums and read the documantation and found no reference to this feature. I've just tried it and, although the URLs are a bit long, they do exactly what I want:
Thanks also for offering to explain the structure of the links. That would be helpful too.
Here are links to the seven photos in your Graveyard Test synth:
In Direct3D: (You'll need Windows, Photosynth, + either Internet Explorer or Firefox 3 [yes, 3 http://bit.ly/vintagefirefox ] to use these)
Great! I see you found what you wanted.
It's been a little while since I looked at the share link variables/switches, so I can't give a comprehensive/authoritative answer, but here's what I remember. Photosynth team members can correct and or complete what I list.
After the collection ID, you'll see the ampersand and then:
m= This switch can be set to 'true' or false'. False is 3D and True is 2D.
Note that the Silverlight viewer seems to not obey the 'm' flag unless you include an image number.
Which leads us to...
i= This switch is represented by three colon separated numbers. I don't know that I've ever figured out the numbering system, but instinct tells me that the first two numbers come into use in synths where there are multiple clusters of photos.
In my previous post, I used a URL shortener because I was using fully articulated share links, but if we are not concerned with the zoom level or orientation of the scene, links to individual images can be shortened to simply:
etc. See previous post for how to modify a link for D3D view.
c= This switch is triggered by three floating point numbers and I believe correspond to the virtual camera's position coordinates (in what appears to be a Z:X:Y arrangement upon initial prodding). Note that you can round these down to a lesser degree of precision to shorten share links when you aren't using a URL shortener without too much loss in fidelity of virtual camera position.
z= This controls your viewport's zoom level (I am assuming, relative to the specified photo). Larger numbers are closer to the current image and vice versa. This number takes a lot of changing in order to make much difference, so rounding the float to the nearest integer shouldn't noticably change things, if you're looking to shorten up your links.
d= Here, again, we have three colon separated floating point numbers which specify the direction that the virtual camera is pointed in. These tend to be fairly sensitive, so handle with care.
I don't know what the last two tags, 'p' and 't' , actually do.
p= contains two colon separated numbers, so is a possible candidate for describing which point cloud in a synth you are currently loaded into.
t= The default appears to be 'True', but don't ask me what this does as setting it to 'False' has no effect that I can discern at the moment.
It allows you to link to different places within a synth without reloading the page and you can choose whether you float directly from one image to another or instead follow a path of other photos from one to the next. Moving from one highlight to the next in this synth is an example of the latter type of transition: http://bit.ly/blueridgehousesynth
By the way, I just wanted to mention that I very much like your idea of photographing cemetaries for relatives to view online. I've wanted to do that very thing ever since I saw a synth of former Photosynth community manager Darius Monsef's, but my Nikon is in need of repair and I just haven't made that happen for the past... nearly a year.
Here's Darius' beautiful example of coverage of a single grave marker:
In Silverlight: http://photosynth.net/view.aspx?cid=2cd3d3f7-2139-4d99-bf2a-d2930c3c33da
In Direct3D: http://photosynth.net/d3d/photosynth.aspx?cid=2cd3d3f7-2139-4d99-bf2a-d2930c3c33da
Story here: http://bit.ly/psfdmnig
Now, if our objective is to cover larger portions of the cemetary in a single synth then we can't afford to dedicate that many photos to each marker, but I'd still encourage you to take a circle of photos all the way around each stone or tight group of stones before going in for the close ups that allow us to read each inscription.
Thanks again for your comprehensive comments. I can now see how, having selected a grave of interest from an index on the church website, I can present the user with a photosynth view of the stone in question.
But - if I might pick your brains again - how can I go in the opposite direction? Can I attach a link to a photo, so that when the user has navigated around the photosynth to a gravestone they find interesting, they can click through to the church website to find more information (such as legible text of the inscription)? Photosynth highlights don't seem to support clickable links. Habe I finally got to a suggestion for a new feature? :-).
@Timjh, I'm happy to help.
As to your question:
"Photosynth highlights don't seem to support clickable links. Have I finally got to a suggestion for a new feature? :-)."
As far as displaying outbound links to other sites from photosynth.net, yes, you're requesting something that does not currently exist.
Notice how the text underneath the synth's title changes as you navigate to different photos (the highlights are a good example of changing text outside the photosynth viewer, based on where you are inside the viewer).
Any time. ツ
