# Using Fourier synthesis to generate a fractional Brownian motion surface

In this post we will discuss generating fractal terrain. In the previous post we implemented our own fast Fourier transform in order to simulate an ocean surface. In that post we implemented an unnormalized inverse transform. It seemed logical to employ our FFT object as a means of generating terrain, but in order to do so we will need to add a method to compute the forward transform. This will be a relatively brief post. Most of the foundation has been laid with our ocean simulation, so we Read more [...]
