[x3d-public] Search by 3d model

[John Carlson]

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The site (http://shape.cs.princeton.edu/search.html) does not say, but I suspect that their database is rather outdated now because they don't have recent formats (sketch-up, FBX, glTF).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
