Now with 256 blocks high level it is possible

are these

mountains still avalible? if not maybe its nice for the extreme hills biome. i found the picture here: http://www.minecraftforum.net/topic/95155-mcserver-a-c-server-by-one-man/

Maybe if FakeTruth can resurrect some of his old terrain generation code. Oh wait, it might be in the svn repository. Makes me curious
But I set out to code IPv6 compatibility today so that's my immediate task now.

i hope these mountains can be put into the generator. they are the perfect extreme hills biome mountains.

I think that used a 3D texture made of fractal noise. MCServer then came with an 8mb file containing that noise xD it's basically just using 3D noise as a density map, very simple but looks cool
RE: Some semi-random thoughts on terrain generation - NiLSPACE - 03-05-2013
yea its awsome
RE: Some semi-random thoughts on terrain generation - NiLSPACE - 03-06-2013
do you think its possible to put it in the generator or should a complete new Heightgen be created?
RE: Some semi-random thoughts on terrain generation - xoft - 03-06-2013
Problem is, this is not exactly height generator. Because height generator cannot make overhangs.
There are two ways of achieving overhangs - either modify the composable generator architecture so that instead of height generator and composition generator, we get a 3D composition generator.
*or* (probably preferably)
keep the height generator and modify the composition generator so that it sometimes generates overhangs in a layer from the generated height to some depth (~sealevel?).

and i gues its pretty difficult to implent into the composable generator.

I'm gonna try my luck with the lake generator.
What I'm thinking is, make a cBlockArea object to hold the lake, fill it with "no action" blocktype, then hollow out a random number of round "bubbles"; fill those with the liquid, if it's lava, make the boundary stone. Then merge the blockarea into the generated chunk using a special merge strategy:
- "no action" blocktype doesn't modify the generated chunk
- liquid blocktype overwrites only stone, dirt, grass, gravel, netherrack or mycelium in the generated chunk
- stone overwrites only dirt or grass in the generated chunk (but not air!)
- air overwrites anything but liquids in the generated chunk
This way, even if a lake is generated inside ocean, it shouldn't be much of a trouble - it wouldn't disturb the ocean, maybe just hollow out its bottom a bit. If a lava lake generates on the surface, its boundary will be stone; at the same time if there is a block on its boundary missing, it will allow the lava to flow out of the lake (good).
The lake's XZ position will be based on a random displacement of the chunk's center coords by a capped amount of blocks, so that only a few lakes can actually intersect any given chunk. The Y position will be capped at the max height in the chunk for which the lake is generated. Thanks to HeightGenCache, that should add only a minimal overhead.
