  The control has several callbacks you can set after creation:

   

  hdv = new hdvHost("hdvControl", "hdvDiv", "100%", "100%", top.location.href, args);

  hdv.setProperty("onRotate", onRotateEvent);

  hdv.setProperty("onTranslate", onTranslateEvent);

  hdv.setProperty("onPanMode", onPanModeEvent);

  hdv.setProperty("onToneMode", onToneModeEvent);

  hdv.setProperty("onProjMode", onProjModeEvent);

   

  And here's an example of using the callback parameters:

   

  function onRotateEvent(f,y,p)

  {

  var ViewForm = document.getElementById("ViewForm");

  ViewForm.FOVBox.value = Math.round(f);

  ViewForm.YawBox.value = Math.round(y);

  ViewForm.PitchBox.value = Math.round(p);

  }

  function onTranslateEvent(z,x,y)

  {

  var ViewForm = document.getElementById("ViewForm");

  ViewForm.ZoomBox.value = Math.round(z * 100) / 100;

  ViewForm.XCtrBox.value = Math.round(x * 100) / 100;

  ViewForm.YCtrBox.value = Math.round(y * 100) / 100;

  }

  function onPanModeEvent(n)

  {

  var ViewForm = document.getElementById("ViewForm");

  ViewForm.PanModeBox.value = n;

  }

  function onToneModeEvent(n)

  {

  var ViewForm = document.getElementById("ViewForm");

  ViewForm.ToneModeBox.value = n;

  }

  function onProjModeEvent(n)

  {

  var ViewForm = document.getElementById("ViewForm");

  ViewForm.ProjModeBox.value = n;

  }
