Did the leaves fall off? Something not working right? Let us know how we can improve the Photosynth experience.
The overhead is out of whack for my synth: http://photosynth.net/view.aspx?cid=3ff0c045-8327-4c90-8b3c-7c3525dc1138&m=false&i=0:1:2&c=29.9309:-10.0742:18.9824&z=455.471136804748. It's not apparent at first viewing, but if you change to different photos and alternate from synth to overhead, you will notice that only the "down" highlight indicators appear. Also, again with different photos, sometimes the highlight indicators are 90 degrees out of alignment with the actual overhead.
I think the up highlights are overlapped to close to the down hightlights.
So either I will reduce the number or change the placement of them.
If anyone has seen this happen and knows of a quick solution please let me know.
Thanks in advance
Jim, you may actually be witnessing an imperfectly joined pointcloud. For what I mean, read David Gedye's reply to this synth: http://photosynth.net/view.aspx?cid=FB5BF8DB-1FFC-4D75-81C9-3711BD29A032
If that is the case, as with synths that are less than 100% synthy, only the highlight indicators that reside within the primary pointcloud will be displayed in overhead view.
As for the highlight indicators being 'out of alignment' with overhead view, I can't say that I'm reproducing that error, so I don't know for sure whether I understand what you're saying, but I assume that you are aware that whenever you are on a photo that is connected to the primary point cloud that you enter overhead view on the vector or orientation of the last touched photo.
The main reason that I suspect that the 'up' highlights are not connected to the main pointcloud (even though you have 100% synthy) is that there is no animation to overhead view, but just a jolt.
This mirrors the behaviour of any synth where you are outside the largest group of images (as defined in grid view) and enter overhead view (simple fade) as opposed to being within that primary group before entering overhead view (swooping animation).
This has lead me to ask for the ability to use overhead view with any cluster of images, rather than just the primary here: http://photosynth.net/discussion.aspx?cat=01b6f15f-42eb-49cb-a221-ed56615e1c47&dis=aabf0d16-9a20-4108-ae3f-a7d456daadab
In other cases highlights do not appear in overhead view where you would expect them to be, simply because the indicator has associated itself with image features further in the distance than what we considered to be the subject of the highlight. See: http://photosynth.net/discussion.aspx?cat=a6bad539-de7d-4a16-8c4d-b143f7d5f984&dis=8356d912-1e43-4612-8459-f6c42f08ab71
I've zoomed out quite far but still couldn't see your 'up' highlights, so I don't think that's it either.
Also, as to your theory that the 'up' and 'down' highlights are simply too close together, you may be right, but I think that generally when two highlights are that close you get the little (+) symbol in the indicator to notate that multiple highlights are available if you zoom in more.
Anyway... those are my initial diagnostic thoughts for whatever they're worth.
After running through the pointcloud in the Direct3D viewer, I'd have to say that I'm right about the ascending and descending pointclouds being separate. There are images at the top that serve as the 'portal' that David describes in the link I listed above that are enough for Photosynth to know that turning around at the top should angle you back towards the descending pointcloud but there is a transition in there where you can clearly watch the one pointcloud swap out to the other.
The other obvious tip off in terms of differences in the pointcloud is the base of the steps at the bottom. If it were all one model, using the fullstop key [.] should get you a normal Photosynth transition from stepping off the last stairs to looking back at them, ready to ascend. Instead we get that sudden teleportation from looking out from the stairs to looking straight back at them with no fun floating in between and it is immediately noticeable, once you're looking for it, that the pointcloud at the base of the steps is now much less dense when ascending.
Anyway... I think I've beat the dead horse long enough now. I wish it were as synthy as the score claims. It just goes to show you that you can't take too many photos when turning around or going around corners.
