Vacuum forming in SU
-
I don't have a laser scanner at all (not to speak about a steady hand)
Really nice work.

Yeah, I thought that would be a nice tool for archeologists, Gaieus
It can replace laser scanning in many places, but at the same time it allows you to have/take much more control.
That dense eye patch mesh was made by drawing a rectangle in one photo, with 5 divisions on each edge.
View locked in one photo, and then PhotoScan did all the rest, including (partial) upsampling of the mesh.
5 min in all? The coarse, textured one was made in patches, with no features drawn, except for top and bottom.
SU applied the photos - a different one for each patch, and then PhotoScan made those textures into one single UV mapped spherical texmap. 10 min?Normally I would draw features and use the tgi3D tools to fit them into the other photos, like on these dumps.
You can't do that with a laser I think?

Interesting...the more I learn about TGI3D, the more I like it. Thanks for the precise info
I think it would be helpful to see a detailed case study using the app...my problem (and perhaps many others' here) is that I don't realize what it can be used for.

There'll be a review in the next CatchUp.

PhotoScan and Amorph are extremely powerful plugins/applications, and I haven't been so quickly addicted to anything since I first met SketchUp about 8 years ago
It's like with the wheel - it looks very simple and easy, but is extremely powerful. In SU this "wheel" is inferencing, and in tgi3D it's called view lockingWhat about all those archeological excavations? You use a lot of sticks, ropes, grids and stuff to measure everywhere. But wouldn't it be useful to quickly and easily make a 3D model of the site, and use it anytime later for measuring distance between anything visible in at least 2 of the photos - with high precision? And at the same time be able to easily reconstruct ruins or disappeared buildings right on site?

There is a relatively small but extremely interesting excavation going on in town now (a 4th century, Late Roman / Early Christian chapel - a so called "cella trichora" for its 3 apses). It's also part of the UNESCO World Heritage so it can also be called "important2 (although not for this sole reason).
I will definitely try the tool out with that. Here is a quick pre-visualization (before we dug up everything). The building will probably be a bit higher (it has extremely thick walls and the Romans were not stupid but good architects who did not waste building material on nothing).

Looks like a great project to try it out with
Be sure to get yourself some telescopic poles for some aerials (I have 2 long + many shorter ones
.
Window cleaners poles (pro), pool cleaners and antennae poles, and microphone booms (expensive!) are all good sources.
But you may already be using such poles? -
Well, the walls that we dig up are quite deep in the ground so I can more or less take photos from above standing there.
However nothing is excluded - a year or two ago, a firetruck came and lifted the archaeologist up in the air to take aerials!
But enough of the Off-topic buildings - this is not about them but your model.

Well. next time you volunteer to arrange the aerials session, and then you buy a pole and use the rest of the money for a PhotoScan license Seriously, I had an aerial photo job a while ago (the poles were far too short for an entire mall), and it turned out that it was cheaper to rent a helicopter for 20 min (it was very close to the airport) than to rent a lift/platform for a day (minimum). 40 min chopper flight == 1 PhotoScan license.@unknownuser said:

Actually it is about using and having fun with PhotoScan, but I found no other suitable category than WIP
