Topic: Point Cloud to 3D Mesh

Report Abuse Report Abuse (Over 1 year ago)
is possible to optmize the Point cloud and make it into 3D mesh? I seen a lot of synth that when turned to point cloud, the detail is just amazing and and enough see the 2d pictures into 3D?

If that's possible, can it be exported to some 3d file formats? I'd like to have that kind of feature in desktop client since the desktop client already performs some complex solving, it could be possible to have it exported from there?

Right you are, amigo. =)

Check these out for saving the point clouds from a synth:

MeshLab 1.3.0 introduced a default plugin for importing photosynths.

Thank you so much! This is what I need. But hopefully, this feature will be available in Photosynth client app (Over 1 year ago)
I saw your synths and I very interested with the one you did here:

Point Cloud was amazing!

I made a test of something like this but in a smaller scale, specifically Shrek. But what I this was the camera is in static position and I am rotating the Shreck toy.

But am not sure why I did not get the result that I expected...

Thanks for the interest. =)

I also meant to link you to some videos of the Spin Movies feature that Microsoft Research demoed at TechFest and MIX this year: The videos in that list show some of what is coming as far as projecting the photos onto dense reconstructions of the scene. I take this to be good evidence that part of what you want should show up on the Photosynth site in the next year as a third imagery type (in addition to photosynths and panoramas).

As to your test rotating the Shrek toy with a stationary camera:  This sort of shooting can be a bit tricky because it requires the background behind the rotating object to be completely blank. If the background is not blank, then Photosynth will try to lock onto both the background and the object and will get tangled up. Photosynth does not reconstruct good point clouds of moving objects because the question it is trying to answer is, "How far is each point from every other point?".

For tips on this sort of shooting, see Page 5 of the Photosynth Photography Guide, available in several languages here:
(If you would like to donate a translation, see this discussion: )

From my perspective, though, it is usually easier to keep the object stationary and just move the camera.
