Greetings, sp2001,

You were asking in the forum why this collection of photos was only 47% synthy. The answer in this case is that you should have taken more photos in between the places where you stood to take 'panorama' type shots. Basically the different parts of the garden that are seen in the photos from angles that are too different from each other. You might be able to get by with the same small number of photos if you could find something further away in the background that is textured enough for Photosynth to track from each position where you stood. It could be anything; it doesn't have to be a building, but the big building at the end of the garden should certainly work.

The simplest trick that I could teach you is to find the major things in a scene that you want to synth and take photos in a circle around each one and then some photos looking from one object to the next and perhaps even walking from one to the other. (continued...)

That approach should get you a nice canvas or framework for normal photos to nest into.

The very best advice that I could teach you is to just watch what other successful synthers have done. Here is one of the first successful cactus garden synths that I ever saw: http://photosynth.net/view.aspx?cid=a01984ff-8b74-461d-875f-09dcf1c2b8dc

Use the period|fullstop key [.] to go through the photos in the order of the names of the photos (usually the order that people took them). You might find it helpful to use the Direct3D Viewer and use the [P] key to turn off the photos so only the point cloud is visible. Using this method (point cloud only mode + period key to walk in the order that the photographer walked) can show you exactly how they approached a scene to get the photos that synthed together.

If you would like to see how my 'circle' method works, please visit: http://photosynth.net/view.aspx?cid=5f415186-f783-43a2-bd5f-92aa3a9603df

By the way, don't think that you have to take as many photos as the synths that I linked to, either.

I also wanted to throw in a couple of synths that do circle objects but do use a 'panorama' style in combination with it.


and even more of a 'panorama' style with this last synth


As you can see, panorama type sequences are not something to avoid, but they must happen close enough to each other so that Photosynth can match all the little groups to each other. Yours were just a little too far apart.

Better luck next time!

Bumped into your synth again this morning and thought I'd share one or two other cactus synths with you.
