Unity + manipulating landscapes through fractals???

Unity Engine
1

Hi im new
I am unsure around the topic of programming 3d fractal landscapes through unity…is it possible?
my idea right now is to manipulate the peramiters and vertices of a given object using a fractal algorithm?
i don’t really know to much and its for an assignment
theres some different techniques: fourier, diamond square and others that use complex numbers
can anyone shed some light on this?? im not a programmer

some links …

Yes, its possible…

Here was one diamond square test,

This one looks very nice,

hey sorry i still really don’t know how i can change the height values of the terrian through script

What you need is the libnoise package. Many people posted variations on the forums some free and some costy.
I posted one free example in the assets forum, search for libnoise

i’ve tried looking up libnoise, it comes up with a noise program, not many other things come up that are relevant
i don’t really understand how it works/helps
sorry for being noob

can anyone direct me to any links or explain on how i can actually change the heights of the terrain through a script?

You can access the terrain heigh values via terrainData.

thank you although…
i don’t understand what this does

var terrainData : TerrainData;

as well with

var heightmapHeight : int;

and what does it mean when it says “Height of terrain in samples”

i don’t understand how to use this
