Geração procedural de terrenos: ambientes externos naturais

Abstract

The constantly increasing scope of modern electronic games consequently demands the ever-increasing investment of time, effort and capital, raising the necessity for methods to facilitate the production of game assets. For that, procedural generation techniques have been widely used in the last decades, bringing to software developers the possibility to vastly expand the quantity and quality of the materials they produce. These techniques consist on the employment of computers and pseudo-random numbers to assist on the automatic creation of game assets. One of the areas in which procedural generation is used is the generation of natural external ambients for games, simulators and movies. In this work, the methods that 3D terrains are implemented, the procedural generation techniques and functions utilized for this purpose are analyzed, and a terrain generator is implemented utilizing the Godot game engine and it's programming language, GDScript. The terrain generator was implemented utilizing Markov Chains and noise generation functions, with emphasis on modularity, aiming to facilitate the addition of multiple terrain types, and the capacity to run in real time. The generator's performance was evaluated by measuring the time interval required to create terrains with different sizes, exhibiting satisfatory visual results, while maintaining the condition of running in real-time.
