Tools for Cultural Heritage applications?


(Jrgration) #81

Hi James,

Very welcome, do let me know if you need further clarification on the suggestions.


(Dbehr) #82

Hi , Thx. for the Model and discussion. How did you get the images to buid the your Model ? How many images and in which Software were they processed ?. Thx. Dave


(Nestor F. Marques) #83

Hi Dave! Most of this questions are answered in the comments of the model itself. Take a look at them if you want.

To summarize though, I took nearly 1400 raw images and they were processed in Photoscan

We've had a few requests now to develop stand-alone temporary exhibits of 3D data where the visitor could interact with the dataset. A simple pinch to zoom, X/Y translation and roll interface with information hotspots, similar to the way Sketchfab works on a phone screen would work well - but it needs to free-standing and "robust".

So my request if for an "Export" format to use in exhibitions. It could burn the sketchfab logo into the corner, that would be fine, but this would be a fantastic exhibition and teaching resource.


(Bart) #85

I understand the need for this feature, but I'm afraid that offline viewing/exporting is not on our roadmap at this moment, sorry!


(Nhm Imaging) #86

Out of curiosity, if we put together a joint public engagement grant proposal, would you consider it?
In other words is this a matter of funding?


(Bart) #87

Update: I've just heard this is something we may consider in the future. I can't give a timeframe though, sorry. And it's not a matter of funding, thanks :slight_smile:

@bartv Not sure if it has been discuss already or planed but lets contribute :wink:

"Highlighting" mesh or multi-texture option
Basically it's like the function highlight in text, painting over the model as it can easily done on meshlab. But it would be interesting to do that while editing the model and that users can enable or disable masks related to it. It would result on "texture selection" by the user.

Our first use of this kind of tool is more for conservators, for example you kind highlight cracks on a statue or replacement. Conservators tend to note all that on images/text.
For the use of general public and education, it can enhance the annotation. For example you click on an annotation that talk about a 12th century construction and the specific part is highlight or surrounded on the model.

Annotations level
I find the annotation already quite nice and very important for CH. But in the case where there are a lot or they are mixed, it could be nice to have different type of annotation specified by the owner of the model (like history/structure/damages...). But I find the annotations a bit underused in general, so it might be possible that there is a problem here, for example not convenient enough. For example I saw it was possible to embedded an image but there is no direct like for it while entering the annotation.
I'm aware this part is also for us to work on it (add more annotation), but I'm just sharing idea.

Law
Big thing and really uncleared.
There are lot of question about reusing models and copyright, mostly when they are from institutions. Even if someone make download available, it doesn't mean we can implement it in our project, mostly if we do business on it ( I'm not talking only about money making type). There are lot of questions regarding the case where we take the pictures or we collect online, plus it depends on the different country etc...
We tried to look at it and it's quite a mess.
It's not the responsibility of Sketchfab of course, just if you happen to find a lawyer expert on such issue, it would be nice to have a clearer idea. It would be particularly important for people doing that has a hobby, like those doing virtual museum and might not be aware of such issue.
For example flickr has different level of copyright access.
I'm not a fan of such topic but as I'm working in CH I encounter often such problem (mostly for pictures).

I hope I didn't repeat an issue or mention something already in place. Thanks for considering user opinion.


(Abby Crawford) #89

@Mesheritage regarding legal issues, we've have had a few conversations in the forum and on the blog. Check out the following:

Hi everyone,

we've published a tool for measuring distances on your 3D models: https://labs.sketchfab.com/experiments/measurements/ .

The tool lets you load any Sketchfab model, click on two points to measure the distance, and use a factor to convert the distance. I'd love to have your feedback about it.


(Mesheritage) #91

Thanks about the link.
I think there are rarely issue as long as there is no money involved, but I notice it was something "new to work on" a bit like drones nowadays (they have rule to settle) but we are making less "noise" :wink:

I tried to talk with people related to copyright and digitalisation, but it was mostly on 2D and scan of text.

If by any chance I found a specialist I will forward!


(Otto Bagi) #92

Great, thanks a lot. Are you planning to implement this into the normal viewer?


(Mauricesvay) #93

There is no immediate plan to integrate it directly in the viewer. Do you have a use case where having it in the regular viewer would be preferable?


(Otto Bagi) #94

I think it would be helpful for quite a few of us when presenting or sharing our work with colleagues. I see your point that this is a very specific tool useful for only a minority of your users and probably you don't want to over-cluster the viewer with a hundred different buttons. However, many people who work in the heritage or archaeology sector aren't familiar with 3-D tools so making this a little more accessible and user friendly would be really helpful. Maybe an option to open the measuring tool from the viewer could work as well (tucked away in a one of the drop-down menus).


(Mauricesvay) #95

We'll think about it. For now, your best option is to include a direct link to a measurable model in the description or in an annotation. Here's a link example to one of your models: https://labs.sketchfab.com/experiments/measurements/#!/models/04bbe38e629e4bca86c1e3ca5a52cc1e

The measurement tool is a great, thanks!! The basic functionality is already enough that we'll be able to pitch is to some of our researchers. Some suggestions:
* Click and drag to move existing points
* Multiple measuring pairs with the ability to label pairs
* Color coding and grouping of measurement pairs
* Ability to save and load measurements
* Value suffix options - cm., m., ", '
* If multiple pairs are possible, it would be great designate one as the control measurement (corresponding to a real world measurement) from which the values for other measurements could be extrapolated
* Ability to select and hide portions of model to easily pick out features to measure
* Ability to combine measurement with fencing - to cut a section from a model

Not sure how feasible any of that is and I'm sure some are more plausible than others, but I hope its useful at least. Thanks for the tool, can't wait to see what's next!

I have just discovered this link to the measurement tool by shear accident. This is a major benefit for the 3D documentation we are doing of archaeological structures and rock art. For a variety of reasons, our models are not geo-referenced and most do not have a scale in the model but we do have a means of determining a length on some part of each of our models. Having the scale factor adjustment is perfect for our application.
Adding a button somewhere in the viewer to easily access this feature would really be appreciated.

It is also noted that some other users indicate having a means of including a direction indicator such as a north arrow would also be useful. We concur, it would really be appreciated even if only an approximation with rotation of the model.


(Wykky) #98

hello
What about scale and point to point mesurement?
Autodesk gallery do it, sketchfab no
:frowning:


#99

We just launched our Sound feature!



(Alex Nan) #100

argh :confused: is this still available or moved to a different site ?
