Issue

It is not currently possible to illustrate chemical files in wiki pages without cumbersome processes (e.g. create externally, change to image and upload).

Background

This seems to be a useful feature according to these:

• https://phabricator.wikimedia.org/T18491(Extension:Jmol)
  • Extension:MolHandler
• https://phabricator.wikimedia.org/T46660

Proposed solution

Evaluate existing libraries that extend three.js

• https://github.com/3dmol
• http://paulbacchus.com/mollyjs-a-webgl-molecule-viewer/
• https://github.com/grahamgilchrist/threejs-molecule-test
• https://github.com/biochem-fan/GLmol

Use existing loader

• https://threejs.org/docs/#examples/loaders/PDBLoader

Evaluate existing implementation in existing extension (Extension:PDBHandler).

Demo:

https://threejs.org/examples/css3d_molecules.html

Extension:PDBhandler in action:

• http://bsd.neuroinf.jp/wiki/%E3%83%95%E3%82%A1%E3%82%A4%E3%83%AB:3h9v.pdb(http://web.archive.org/web/20170430144452/http://bsd.neuroinf.jp/wiki/%E3%83%95%E3%82%A1%E3%82%A4%E3%83%AB:3h9v.pdb)

• http://bsd.neuroinf.jp/wiki/P2X%E5%8F%97%E5%AE%B9%E4%BD%93

Notes: currently pdbhandler seems to work in file pages and article pages, so it actually works better than extension:3d for now, probably because on average they are likely to be smaller than a normal 3d file.

I bet there's some folks from WikiProject Chemistry who would love this feature as well. :)

There's a few phab tasks related to this request. I've added a note to them.

Thank you again for the thoughtful suggestion. They are often informative and you're always kind in presenting them.
