It's simpler for real . In my case , I want my frame rate updated on higher frequency when I'm inputting keyboard actions . So I guess I have to go outside animator and put draw functions in a self-designed thread . I wonder from GLAutoDrawable.invoke() , makeCurrent() , Canvas.display() which is the best option should I use to draw something outside animator ?

It isn't, what you describe is probably doable with a plain Animator or FPSAnimator. However, yes, you're on the right path with GLAutoDrawable.display() and GLAutoDrawable.invoke(), you can use them when you really want to avoid using an animator, this is what I do in JogAmp's Ardor3D Continuation. Your use case looks like something related to scientific visualization, I had to implement something very similar to mimic OpenInventor many years ago. Why would you need a self-designed thread? The events would come from AWT and the drawing could be done on the AWT EDT too.
