I do like playing with terrains.
Generally there are two ways of rendering terrains or landscapes, the first one is called voxel, the second one is using 3D triangles.
There are difference between the two ways, both in theory and the result.
Many flashers did some very impressive experiments about terrains by action script.
1.A great one was Electric Oyster 's flash flight simulator over the arctic.
The swf is based on their own 3D engine-Electric 3D engine using tiangles way to render the terrain.
Great texture and rendering speed!
for full screen version it will be 'data_hq.bin'
you may need to take care of flash player's security problems.
2. away 3D greenpalnt demo

3. Den Ivanov did lots of beautiful experiment on terrain.
The most famous one is his land craft simulator in flash 8.
He also did other simple voxel terrain with source their
And triangles.(with source)
Voxel is much more month, on the other hand you can recognize the triangles

This one shows how triangle works.
