Projecting Overlays

IOverlayRenderer

Basically, you get the world model and edit session there, and every time your overlay projection is to be shown, you get offset coordinates, clipping and a graphics context to draw upon - then you're at your own.

Typically, you will want to register your overlay renderer with a console service to get information from some other component, i.e. an agent. You'll then store this information in a cache in your renderer and use it for drawing when requested.

To make your overlay renderer know to Eclipse, you must use the extension point "org.micropsi.worldconsole.overlays". Here's an example:

<extension
    point="org.micropsi.worldconsole.overlays">
  <overlay
    name="Test overlay"
    class="org.micropsi.eclipse.myplugin.MyOverlay"
    zOrder="2"
    id="org.micropsi.eclipse.myplugin.myoverlay">
  </overlay>
</extension>
