    • processEvent

      public void processEvent(AWTEvent e)
      This override let GLUT.processEvent(AWTEvent) be informed of AWTEvent traversing this canvas (mouse, keyboard, resize). One should register GLUT.glutDisplayFunc(String) to register a display callback, GLUT.glutMotionFunc(String) to register a mouse motion callback, etc. NB : This relies on the fact the GLUT already invoked
      invalid @link 
      {@link this#glut_enable_events
      }.
      Overrides:
      processEvent in class Component

      Overrides:
      paint in class Canvas

    • getPixelScaleFromG2D

      protected void getPixelScaleFromG2D(Graphics2D g2d)
      Pixel scale is used to model the pixel ratio introduced by HiDPI

    • setGL

      public void setGL(GL gl)

    • forceRepaint

      public void forceRepaint()
      Can be used to update image if camera has changed position. FIXME : Warning if this is invoked by a thread external to AWT, maybe this will require to redraw GL while GL is already used by AWT.
