3Dmol.js

CDNJS codecov Github CI

3Dmol.js is an object-oriented, WebGL accelerated JavaScript library for online molecular visualization.

Since 3Dmol.js is licensed under the permissive BSD open-source license, you are free to use it in any project, as long the code is properly acknowledged and cited.

With 3Dmol.js, you can add beautifully rendered molecular visualizations to your web applications. Features include:

  • support for pdb, sdf, mol2, xyz, cif, cdjson, mmtf, prmtop, gro, pqr, cube, and vasp 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

See the documentation to learn how to use 3Dmol.js as a hosted viewer, embeddable viewer, or as a component of a larger application.

Examples

HTML

<script src="https://3Dmol.org/build/3Dmol-min.js"></script>     
 
 <div style="width: 400px; height: 400px;" 
        class='viewer_3Dmoljs' data-pdb='4N8T' data-style='cartoon:color=spectrum'
        data-surface='opacity:.7;color:white'></div>

JavaScript

We support the use of both PDB queries as well as PDB files.

Alt Text

First you simply create the viewer with a div's id.

var viewer = $3Dmol.createViewer($("#div"));

Then you can download a protein data bank model (here pdb:1MO8) and display it with the styling of your choosing.

$3Dmol.download("pdb:1MO8",viewer,{multimodel:true, frames:true},function(){
	viewer.setStyle({}, {cartoon:{color:"spectrum"}});
	viewer.render();
});

Surfaces

We also support the use of surfaces that are asynchronously loaded and support different color schemes

Alt Text

viewer.addSurface($3Dmol.SurfaceType.VDW, {
    opacity:0.85,
    voldata: new $3Dmol.VolumeData(volumedata, "cube"),
    volscheme: new $3Dmol.Gradient.ROYGB(range[1],range[0])
},{});

Shapes

The use of different shapes and styles is supported.

Alt Text

viewer.addCylinder({start:{x:0.0,y:2.0,z:0.0},
    end:{x:0.0,y:10.0,z:0.0},
    radius:0.5,
    fromCap:false,
    toCap:true,
    color:'teal'});
viewer.addCylinder({start:{x:15.0,y:0.0,z:0.0},
    end:{x:20.0,y:0.0,z:0.0},
    radius:1.0,
    color:'black',
    fromCap:false,
    toCap:false});

Documentation

Please check out our documentation at 3dmol.js. We have tutorials, as well as the stable release of the platform.
