how to render a infinite terrain or world?

as the feature say,infinite world can be made by using this plugin.but there is no doc or code for instruction,i hope somebody can tell me the method to make it and send me some codes.my e-mail is:archmager@126.com.
my english is poor,i hope the words is not perplex.thank you!

Look at Example6. If you comment trees->setBound(...) out in the example the trees will be infinitely drawn in the world. I haven't played with the example a lot but hopefully it will get you started on the right path.

If you mean that you want to draw infinite terrain then you need to look at paging landscape manager. Paged Geometry won't be the solution for that.
