How can I fix it so that the code creates landscapes with hills and plataus?
Thank you for your help.

Help with setting initial variables
Author
Hi :),
I am trying to implement the code here:
Java World: Fractal Landscape
in VB.Net. My code:
My Code
Ive set the initial roughness = 0.95 and initial LOD = 10
At each level of the diamond-square algorithm the roughness is recalculated to rough=roug*roughness
But the result looks nothing like a landscape. It has little pertubations throughout but no macroscopic features.

You need to add some lower-frequency data to the map in order to create "bigger" features.
Read up on "Perlin noise", that will give you ideas on how to proceed.
Plateaus are usually simulated by a response curve that flattens to horizontal on the topmost values. In reality, plateaus and ridges are formed by corrosion caused by water and wind as well as the irregular composition of the ground material itself, so for realistic results you might want to simulate that (at least statistically).

Hi. Thanks for the help. I tried setting different values from 0.1 to .9 (the value has to be greater than 0 and less than 1) without success

Could the values be getting overwritten as diffreent levels of diamond sqaure algorithm are being run?
