This demo shows how you can change the position and content of annotation.

var sceneId = 'ba27edd2-8037-47e8-ab71-112e52053fac';
var api = claraplayer('player');
var wireframeModes = ['Normal Render', 'With Wireframe', 'Only Wireframe'];
var wireframeModeSelect = document.getElementById('wireframeModes');

api.sceneIO.fetchAndUse(sceneId).then(function() {
  wireframeModes.map(function(mode, i) {
    wireframeModeSelect.options[i] = new Option(mode, mode);
  });
  document
    .getElementById('baseScene')
    .setAttribute('href', 'https://clara.io/view/' + sceneId);
  wireframeModeSelect.onchange = changeHandler;
});

function changeHandler() {
  var mode = 0;
  if (wireframeModeSelect.value === 'Normal Render') mode = 0;
  else if (wireframeModeSelect.value === 'With Wireframe') mode = 1;
  else if (wireframeModeSelect.value === 'Only Wireframe') mode = 2;

  api.player.setWireframeMode(mode);
}
