The Diamond-Square Algorithm is the natural first stop for generating artificial landscapes. The algorithm itself is beautifully simple (more details below, and on its Wikipedia page). But a casual implementation ended up not working at all, prompting me to look for an existing implementation to learn from. However, most implementations I found looked hideously complicated (or just hideous), not necessarily correct, and/or used out-of-date programming languages and styles. It therefore seemed like a good idea to create a clean, simple “reference” implementation of this algorithm, using a contemporary and widely known programming language and style.
Gnuplot in Action, 2nd Edition, is the authoritative guide to the gnuplot graphics and visualization program for developers, engineers, and scientists.
With this insightful book, intermediate to experienced programmers interested in data analysis will learn techniques for working with data to discover what it contains, how to capture those ideas in conceptual models, and then feed your understanding back into the organization through business plans, metrics dashboards, and other applications.
Gnuplot in Action is a comprehensive tutorial written for all gnuplot users: data analysts, computer professionals, scientists, researchers, and others. It shows how to apply gnuplot to data analysis problems. It gets into tricky and poorly documented areas.
