3Dmol.js is an object-oriented, WebGL based JavaScript library for online molecular visualization - No Java required! With 3Dmol.js, you can add beautifully rendered molecular visualizations to your web applications.
Features include:
- Support for pdb, sdf, mol2, xyz, and cube formats
- Parallelized molecular surface computation
- Sphere, stick, line, cross, cartoon, and surface styles
- Atom property based selection and styling
- Labels
- Clickable interactivity with molecular data
- Geometric shapes including spheres and arrows
Molecular data can be shared and visualized without writing any HTML using only a declarative URL specification and our hosted viewer (see {@tutorial url}).
Viewers can be quickly embedded in any HTML document using just two lines of source code (see {@tutorial embeddable}).
| Movement | Mouse Input | Touch Input |
|---|---|---|
| Rotation | Primary Mouse Button | Single touch |
| Translation | Middle Mouse Button or Ctrl+Primary | Triple touch |
| Zoom | Scroll Wheel or Second Mouse Button or Shift+Primary | Pinch (double touch) |
| Slab | Ctrl+Second | Not Available |
3Dmol.js provides a full-featured API for manipulating and styling molecular data.
The library is available as a single minified JavaScript:
<script src="https://3Dmol.org/build/3Dmol-min.js"></script>
An un-minified file is also provided for debugging purposes:
<script src="https://3Dmol.org/build/3Dmol.js"></script>
The files hosted by 3Dmol.org closely track the development version and so will change frequently. If you desire more stability you may copy the files into your own project or, alternatively, we host release snapshots on the cdnjs content delivery network (note that you must specify the release version). Do not use the CDN minified version (3Dmol-min.min.js). The CDN autominifier does not generate correct code and 3Dmol-min.js is alread minified.
<script src="https://cdnjs.cloudflare.com/ajax/libs/3Dmol/2.0.1/3Dmol-min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/3Dmol/2.0.1/3Dmol.js"></script>
Using the CDN will likely provide the best network performance to your users, but features will lag behind the development branch as we only plan to tag new releases a few times a year.
If you are using a bundler such as Webpack or Parcel and your code is in TypeScript or using ES6 imports (and after maybe using Babel to transpile it), then you will want to import it like this:
First add the library to your dependencies:
npm install 3dmol
# or yarn add 3dmol
Next, you need to import 3dmol.
import("3dmol/build/3Dmol.js").then( ($3Dmol) => {
console.log($3Dmol);
//can do things with $3Dmol here
});
or if you use an expose-loader to make jquery globally visible you can use flat imports.
import * as $3Dmol from '3dmol/build/3Dmol.js';
Note that even when loaded as a module, the $3Dmol window global will be populated.
The full source distribution is available from github.
git clone https://github.com/3dmol/3Dmol.js
cd 3Dmol.js
npm install
The npm install command will take care of building the project with webpack. To rebuild it again use npm run build. This will allow you to access the completely built file at build/3Dmol.js.
Since 3Dmol.js is licensed under the permissive BSD open-source license, you are free to copy this code and use it any any project, as long the code is properly acknowledged.
Every 3Dmol.js viewer canvas corresponds to a {@link $3Dmol.GLViewer} object. The viewer object includes methods for setting viewer properties and for creating and manipulating molecular models, surfaces and custom geometric shapes within the view.
A {@link $3Dmol.GLModel} object represents molecular data. Each model object stores its own rendering data and provides a convient way to reference a defined part of the scene.
Models are manipulated and styled using {@link AtomSpec} JavaScript objects.
An example of a viewer that manipulates the styles of the embedded objects is shown below. View the source code for the implementation details.

Nicholas Rego and David Koes 3Dmol.js: molecular visualization with WebGL Bioinformatics (2015) 31 (8): 1322-1324 doi:10.1093/bioinformatics/btu829
Due to limited resources, our focus is on developing 3Dmol.js as a molecular viewer library, rather than a full featured cheminformatics/bioinformatics toolkit.
For example, adding support for WebGL 2.0 has a higher priority than adding editing functionality to the hosted viewer.
We hope others use 3Dmol.js as a building block for such web applications and look forward to collaborating with web developers to deliver the visualization functionality needed to enable them. Of course, if additional resources become available we may expand the scope of our efforts. However, the goal is to keep the core of 3Dmol.js as small as possible and focused on visualization.
Time permitting, we will add support for additional formats as they are requested. We also hope to integrate with other cheminformatics libraries to automatically provide additional formats and analysis.
Yes, as long as they support WebGL. For example, it runs great in Safari on an iPad running iOS 8.
