Terrain generation strategy (need ideas)

Hi!

After very successfully experiments with jme2 and the great help around here I managed to get my small terrain with movable camera done.

I have been using MidPointHeightMap generation.



Now I would like to generate a larger landscape using TerrainPages / TerrainBlocks.

This is now out of my knowledge and I would like to get some hints / ideas please.



My problem is that MidPointHeightMap generation is allways random. Is there a seed I can set so it generates allways the same land? Dont understand me wrong it can be random but I would like to have some control over it.



And how could I manage the borders from multiple generated HeightMaps to fit perfectly together?

Imho if I can get the borders to fit I would be fine.
