Exploring Archicad: Algorithms and Parameters with GDL Coding
The main example is a procedurally generated terrain object based on a two-dimensional version of Ken Perlin’s noise algorithm. It is resource- efficient and involves relatively simple mathematical computations. The main control parameters are the amplitude values, which control the maximum height of z values; the frequency value, which determines how fast the results are sampled to control the “bumpiness;” and the number of octaves.
