Mountain outline formula

#1

Is there a good formula for generating random mountain outline?

#2

What kind of mountain outline? 2D? 3D? Pixels? Polygons? Think about what you are asking a bit first, we cant blind guess.

#3

Sorry.I want to create 2d polygon mountain.

#4

This might be of interest. It’s a simple 2D fractal technique using midpoints. Very simple, can tweak to yield good results.

#5

Thanks I will use this.

#6

Also, as such a terrain is composed of lines, you could use the simple collision technique I showed here should you need collisions.

I successfuly generated mountainous terrain using a simplex noise generator in octaves.

Here’s the code for the SimplexNoiseGenerator:

Here’s the actual terrain generation in octaves:

I think the prototype is currently not working, but this generator code works fine.
