[x3d-public] Search by 3d model

[John Carlson]

Hypermedia database == WWW
Multimedia database!

Now, how do we add model and controller searching to Hypermedia?

Where do I go to query on some of the things I’ve been mentioning?  Does YouTube provide search by clip?   Can I search movies by image?

How does one provide the full experience of Hypermedia, Content Search and Interactivity desired of the WWW? In an X3D/HTML5 browser?  Specialized sites are acceptable for the first implementation.

So “searching by animation” eventually led me to motion databases and video surveillance systems.

Do professional animation authoring tools offer search by motion?   Does someone know of a search by motion system on the web?

Who is doing structure and motion querying research? Is there any with self-driving cars?

Thanks,

John

I view there being 3 types of hypermedia (aka presentation or view): Movies, Text and Shapes (3D).  I do not see why searching by part or sketch (model, mesh, content or data) is not acceptable. For example, there is, based on looking at Masaki Aono’s site:

part-based 3D shape retrieval
Sketch-based 3D shape retrieval


So there’s content and presentation retrieval.  The part/sketch based retrieval appear to be more focused on content, and the image/text/shape based retrieval appears to be more focused on presentation.  I am interested in content/data retrieval at this point (how the data/meshes/transforms are connected), and not presentation (not what it looks like).   I am looking for a part/sketch search engine on the web that includes an add-on for sketching, or upload for content.

I am also interested in search by action or animation (controller) if such a thing is possible.   Is something like Nagios still acceptable for this?

It’s not that presentation search is unimportant or it doesn’t work.  I am currently building a bigger picture of the search and retrieval pattern based on MVC.

I am thinking that Tesla has the database to implement this on.  Perhaps I should submit my resume to OpenAI.

John,

Browsers do not support plugins anymore. You can have an add-on, but the processing is not the same. 

The site (http://shape.cs.princeton.edu/search.html) does not say, but I suspect that their database is rather outdated now because they don't have recent formats (sketch-up, FBX, glTF). I am not sure that the engine would be of much use. The research work they are doing might be, but it does not appear to be publicly implemented at this time.

I don't think a scene graph would be a good way to go. The same visual model may be represented in significantly different scene graphs. I still my original suggestion of keyword and/or image search would be best.

Okay! I am imagining searching by 3D mesh or unnamed shape/volume, I guess.  That is, something that won’t be confused by colors.
 
I think the Princeton site will be perfect if I can get it going with Java or OpenJDK.  I am looking for a more up-to-date site, without the dependency of installing Java (and Oracle’s new license). Thus I am looking for an OpenJDK browser plugin for Chrome (or other) on Windows 10. I don’t really want to step down a rabbit hole.

I’m now guessing I should be looking at either semantic network search or social network search for a potential solution.
 
Search by scenegraph?

Not sure what you are trying to do here John. All good websites will supply sufficient meta-tags for the model to allow a search by text. If you are trying to find a model based on the look of one you have, try using a screen shot. Google's image search is pretty good.

Can someone direct me to a “search by 3d model” engine which doesn’t require java in the browser?  Thanks
