If you get pinged by my reply, take a look at
http://photosynth.net/view.aspx?cid=aae9cb93-63ed-435c-aa85-21a3b95cd4e5. That synth is crappy, yet I took a 360 view of the turtle, and yet only a few photos made the grade. I was disappointed.
And how do you string synths together?
Hey, nice synthy percentage score you got here! This really does give a nice look around your garden.
If you were expecting more of a 3D point cloud (press the [p] key to cycle through photos+points, points only, and photos only), I'd suggest practicing by focusing on just one object at a time until it feels a little more familiar. Try synthing one tree or one flower at a time and those should yield much more of the 3D model. Once you've got the knack of it, it's simple to string multiple things together in one synth and get a pretty fair sense in 3D of what you photographed.
Again, nice shots. I love how Photosynth lets you zoom in on the details of leaves, bark, petals, etc. I hope to see more from you soon. :)
