Meru mod is a vertical 1 dimensional realm, 1D referring to large scale structure, and can act as a vertical connector between horizontal realms, such as the ground and the floatlands.
A single spike shaped mountain is created in newly generated chunks, at a random location within a chosen area; by default this area is +/-1024 for use in a new world, to add a mountain to an existing world you need to edit these area parameters to a completely ungenerated part of your world.
For testing this mod or for cheating edit parameter COORD = true, the co-ordinates of the mountain will be printed to terminal while within the generation area.
The mountain is a hollow cone made of stone and desert stone, with a smooth transition across biome boundaries. By default the height is 2km. There are a few cave entrances on the surface, these 'fissure system' caves expand under the surface helping the creation of a path upwards. If the mountain generates over water you can use the central conical void to jump down the last few hundred metres.
There are many parameters for fine tuning the structure, some parameters change smoothly with height or distance from the center. Reducing noise to zero at the center creates a perfect spike as a summit. Constant noise throughout often creates floating islands at the summit. Choosing zero noise throughout creates a smooth geometric conical shape. There is a parameter CONVEX to control whether the basic conical structure bulges outwards or is pinched inwards in the middle.

ZOMG
PLEASE.

Sheet. Now I have to clean the drool off my kindle.

Awesome! Found a patch of jungle on the side of one:

Does it affect lag a lot?

Yes. The blocks that contain the mountain take a long time to generate.

SO COOL but im not downloading

This. Is. Amazing.

The mountain is amazingly high, and it was really fun creating a hiking trail to the very top. I also like the idea of the mountain being hollow.

how do I get the lag from my minetest?

Install all my mods then you'll get the lag big time ;)

I don't understand why all your mods are so laggy... Is it the perlin noise that takes time, or env:add_node ?

It's because my mods generate huge structures and LUA is slow, lag is unavoidable, ... I need a faster computer.

Shouldn't you have a link to the original flolands mod?

Good idea, done.

Just tried this. It seems to be not that laggy with luaJIT.

I just installed this last night and scaled the mountain. I concur it wasn't too laggy with luaJIT.

Lua is one of the fastes Launguages.

it looks like an island from SAO i'm so excited about it o.o

maybe make placement random and create ones with lava in hollow core.

I've been playing with this, hoping to make the spawn random.
I found a way to control the noisyness of the structure, to enable smoother tower like shapes. The cave system will be the new fissure system which provide occasional paths upwards. This mod needed much attention i will release a new version soon.

I like the fissure system, so your next release will be an interesting one.

So here is my current problem, how to generate one tower at a random location (within x z +-1000). A solution i saw in the 'modding questions' thread will not work because a meru tower occupies hundreds of chunks and may take more than one session to generate.

So i thought of deriving a co-ordinate from the world seed, but that seed seems to be not easily or quickly accessible from within a LUA mod.

Any better ideas? I need one random x z co-ordinate per world for the tower that can be quickly checked against the current chunk by an on-generated function.

You could use your perlin maps for three random places on the map.

Did you try using

?

Thanks for the suggestions, with kaeza's help i am now able to load the worldseed from map_meta.txt and will try using that to define a co-ordinate.

Thanks Jordach ... just realised it can be done with perlin noise :)

EDIT
It works.

Version 0.2.0. First post rewritten.
Wider, unlimited height, fissure cave systems, random spawn within a chosen area, parameters vary with height and distance from centre.

Version 0.2.0 now pushed to Github (at last), link in first post.

I cant find the mountain!

Same for me... Do we have to generate it or to find it?

I had to find it. I used the mapping program http://forum.minetest.net/viewtopic.php?id=2896 to map my world and found it and ran to it. Turned out it was out of my sight because of the low sight values.
