Organic modeling from photos?
-
you're too kind.
-
Here are the photos.
The rock has a total height of 12.5 m, the plate is 7m x 7m and 3.5m thick.
Has someone experiences with the Arc3D service? If it worked, I think it would be the best solution.Thanks for the replies

Hello-
New guy here. This is my first post actually. Just wondering where this rock is located. If its famous enough, there mught already be some 3D data available on it, in the form of DEM data, survey work, or even some simple "terrain" image from Google Earth itself. You might also be able to work it out with enough images using Photomatch. Start off with a square "blocky" version and then refine it later. Just a thought. Good luck with it.8-Perf

Looking at that rock, it is quite angular anyway. Give photomatch a go.

You could give this a try

Many Thanks!, it has been solvedlong ago:
http://forums.sketchucation.com/viewtopic.php?f=18&t=18244&hilit=+organicI didn't find a better solution than modeling it by hand, until it fits from every perspective to the outlines of the photos. My favorite alternative was the following:
Arc3D http://homes.esat.kuleuven.be/~visit3d/webservice/v2/
Creates automatically models from many photos. Seems to be promissing and very accurate, but off service.Sketchup photomatch
Very accurate, if you have really orthogonal geometry (not in my case).pixdim or http://www.photomodeler.com
Similar to photomatch, but using two photos (i.e. stereo photos). Very accurate, if you can place the black/white reference points before taking high resolution photos. Otherwise (photos from web) not accurate.Archipelis http://www.archipelis.com/product.php
Good for rounded things, not accurate.http://make3d.stanford.edu
Uses only single images and makes a very inaccurate guess of the depth info. But nevertheless impressive.http://www.photo-to-3d.com
In the free version, it uses only two images of low resolution and was not able to create any polygons. -

2. I tried Microsoft photosynth which creates a 3d point cloud and uses it for a slideshow in 3d space. But photosynth can not export the 3d data.
Now you can http://binarymillenium.com/2008/08/exporting-point-clouds-from-photosynth.html + http://meshlabstuff.blogspot.com/
Might want to look on this http://binarymillenium.com/2008/08/photosynth-export-process-tutorial.html

http://news.creativecow.net/story/866538 i went looking today... found this...
'(Venice, California--June 7, 2011) Lightcraft Technology, a developer of real-time visual effects technology for the film and television industries, announced that it is making its photogrammetry tools available free-of-charge to its clients and to members of the film making community.'
if the license allows... i'm up for making virtual dress forms, and imvu stuff. mom does some indie stuff, has had something go into the nfb archives... and she could use some 3d junk... if that's what i'd need to do to justify the terms.

You may want to give Tgi3D photoscan a try.
http://www.tgi3d.com/ Trial version is unlimited free for 30 days. -
I have no idea how well that Lightcraft toolset works, but according to the info in that link it is a set of Maya plugins, making it useless if you don't own Maya (which I don't).
I have used such photogrammetry software for many years, PhotoModeler and ImageModeler, and now also Tgi3Ds PhotoScan (with plugin for SketchUp), and I can tell you that with PhotoScan making such a model should be much easier/better than with those two other tools.
There are also some free "3D scanners" available, but AFAIK they all produce huge, dense point clouds, which wouldn't be very useful for SU/GE work.
With PhotoScan you can control exactly how much detail you want in the geometry and how much detail you leave up to the textures (applied right inside SU with PhotoMatch tools).Some of the photos you posted are croppped, which is not good for any photogrammetry software..
-- I noticed that the thread is old, so the "case may be closed" already?

Salut Pilou!
I will add my review of Photofly to this very very old thread:

You could get a long way with a camera pole too
Out of curiosity - is that rock model on GE now? If it is - where is it exactly?
Looks like a very strange formation.And did you try PhotoScan too?

Not my area but maybe worth a read

Photosketch looks nice, but it is advertised as a tool for creating lowpoly buildings inside SketchUp.
Just like SU's own PhotoMatch, but with some automation, like undistorted photos, point clouds and higher precision?What dense point clouds does is using brute force, just like when using DEMs for generating landscapes. You really often need millions of polys to get a well defined model with crisp details/creases. It often ends up looking like a metaball/blob object.
The beauty/power of PhotoScan is that it gives you the tools to model from photos fully controlled, and even make very dense automatically surface-fitted meshes like with point clouds, if that's what you want.
And it can be used with any object, buildings, complex/concave organic forms, terrain - even with glass and shiny objects (which never works with point cloud mesh generators).
I really doubt that any of the point cloud generators would have any chance to make an automatic model of something like this sharp edged, complicated/overlapping stainless steel sculpture?
