This program simulates a mountain by creating randomly oriented pyramid structures and then placed them on top of each other.
The parameters:
H = height of new pyramid
(A,B) = coordinates of peak (random)
P = “jaggedness” -1<p<0 gives very jagged mountains, while 0<p<0.5 gives very smooth hills
Q= parameter resets the height
Iter = number of iterations
Equation for height of pyramids:
H = (P*height)/(-2^(mod(iter,Q)))

Using the Perron model of landscape erosion, we can use this code to set the initial conditions of a mountain in order to model mountain erosion. These images were made by combining the two codes into one.
