I have the Terrain Node source code. It compiles, but it does not work.
The screen is black and crashes when space is pressed : In this case the glPolygonMode is altered.... using both test examples.
Any suggestions?
Bye!

That was code by Christoph Fuenfzig. I just realized that I never
checked that into Contrib. I just did it, you can check it out and take
a look. I haven't tried it in a while, though.

The problem is that it depends on your STL implementation, which differs
from system to system, and from compiler to compiler. If clear() frees
the memory it could be a problem. But there is not really that much you
can do about it, as set will probably also do a realloc.
