addLabel() - Create Text Labels


How to create text labels with 3Dmol.js addSphere() methods?



viewer.addSphere() method in the $3Dmol.GLViewer class allows you to create sphere objects. Here is the signature of the addSphere() method:

{$3Dmol.GLViewer} addLabel(text, {LabelSpec} options, {AtomSelection} sel) -> {$3Dmol.Label}

Here is an HTML code example, Draw-Label.html, that uses the addLabel() method:

<script src="/3Dmol-min.js"></script>
<div id="viewer" style="width: 400px; height: 400px; position: relative;"/>
  let config = { backgroundColor: 'grey' };
  let viewer = $3Dmol.createViewer( $('#viewer'), config );
  viewer.addBox({center:{x:0,y:0,z:0},dimensions: {w:3,h:4,d:2},color:'magenta'});
  viewer.addLabel("Corner", {position: {x:1.5, y:2.0, z:1.0}, 
    backgroundColor: 0x804040, backgroundOpacity: 0.5});
  viewer.rotate(45, {x:1,y:1,z:1});

This example HTML code will display a text label with a 3D box as shown below:
