User:Reaper35/3D-Data

This is a project page and collects my ideas, thoughts and other necessary information needed to provide 3D data on Wikipedia.

Tasks tracking this feature and related tasks:

• T3790: Allow uploading of 3D files to Wikimedia Commons
• T93679: Uploading and Displaying 3D files with Fallback
• T54655: Add support for thumbnails and interactive views of 3D models
• T45616: Provide a way to create interactive 2D/3D timelines and infographics e.g. Java applets, AJAX, Flash
• (and more)

About

Allow the presentation of 3D data (directly) in articles using WebGL. (Based on maybe OSG.JS (http://osgjs.org/) or Three.js (https://threejs.org/). List of WebGL frameworks)
3D objects could (or should primarily) be created using photogrammetry which could end up in highly detailed 3D objects and point clouds. The objects could contain up to 1~2 million polygons it would still even work for older PCs.

It could be used for:

• Archaeological objects like temples, historical buildings, archaeological sites in general, sculptures and similar
• Technical visuals
• In combination with animations. (Could be hard to do, but an idea.)
• Volumetric Data (but even much more complicated to program / high system requirements)

• Biology
• Medical visuals

• 3D vectorial data as wire-frame models. Used for:

• 3D wire-frame models of technique and similar
• mathematical objects like surfaces

• Sites viewable as 360° panorama photographs of sites (like Google Street View)
• ...

Some other notable Examples:

• 100.000 Stars (seems it doesn't work with Firefox)

Examples could be found e.g. on the website of Sketchfab (which uses OSG.JS).

Related feature (easier way, for simple/smaller objects):

360° turn around picture viewer (object in mid, cam moving around)

To Do

Problems to be solved:

• Thumbnail rendering on server side

To be processed:

• Which file formats are usable, pros and cons. Collection:
  • .obj: Wavefront .obj file
  • .glTF: https://github.com/KhronosGroup/glTF
  • .dae: COLLADA
  • .X3D: X3D
• Comparison between available JavaScript libraries for rendering:
  • OSG.JS
  • THREE.JS

(To be continued.)
