And an octree class that I made in a similar way, it puts all the vertex array stuff in the leaf nodes and can either draw them and store in display lists or draw them 'live' if the terrain needs to be deformable.

Apart from that it's just a textured heightmap and more home made functions!!
That's what I was asking about, but I couldn't think of the correct term. Btw, I may be able to throw a crazy idea or two your way for a game story - I'll see what I can come up with. :idea:
