This is the source of the demo on the jogl website, I have studied it for a lot of time ; but still have many questions about it . (English is poor, say sorry first)

The code source is in the attched text.



The questions are these below:
1,How does the rotation of the gears implement in the code?
2,I haven't seen the revoking of the function of reshape(), when does it be revoked?
3,Can you explain the details of the dimeson of the GLCanvas in the jogl?
4,I once saw the user-guider of jogl ,it say that the init ()  is to revoke when setting the environments of the redering, and display() is to implement some detailed jobs of redering ,such as redering the picture,and reshape() is to revoked when some circumstance is changed, but  I still have doubts.Can you teel me the sequence of these three functions to be revoked?


Thank you very much!

It is a simple example, and I want to say thank you  and that it maks me clear.
