Ive just started playing around with photosynth...but i was wondering how you go about getting the pint cloud...or does the engine just add this when its needed or can be done? thanks guys...some of you have done some amazing synths...im impressed with the engine and the work from you guys...

Basically, the more photos of an object that you take, the better the point cloud will be. Yes the photosynth engine does all the work. To make the best synths you have to start to think like the engine, or in other words, make a plan of what you will shoot and what would be the best shots in order to get a good point cloud. You will get the hang of it in no time.

and you must change the angle of view by walking around (or rotating a turntable); then the program will (try to) rebuild the object in 3D so you can see the different sides on your flat screen (and eventualy you get a point cloud)

I have only a point cloud and nothing else, no photos or anything. Complete Noob, what am I doing wrong?

jon - You probably hit the p key.  This will cycle you through 3 modes - photos only, points only, and mixed.

This is another unfortunate change I was trying to tell the tech guys about.
You used to be able to (and still can in the  Direct3d viewer) hold down the control key while navigating and you would see the point cloud. You could continue navigating and rotating the cloud while holding the key. Releasing it brings the photos back into view. You can see the cloud and the photos at the same time and toggle and IT'S AWESOME.

But with the Silverlight viewer that control key function is not there! A very disappointing thing upon an experienced users first use. You can press the "P" key, but that just cycles through rather then the elegant toggle. And the P key is in an annoying spot on the key board. You have to take your eyes off the screen to find it, which interrupts the previously fluid navigation of content.

So to answer the question, it's automatic, but to see it impressively you need to use Direct3d viewer and hold control key at any time in your navigation.

Interestingly in the Direct3D viewer, even when you had used the [p] key to toggle to points only, the Ctrl key would return you to photos + points, acting essentially as a way to step backwards from pointcloud viewstate 2 to viewstate 1.

The Ctrl key is back!  With our recent update we turned it back on.  Enjoy, I know I will.
