A Survey of Procedural Content Generation of Natural Objects in Games

The natural environment is one of the important research fields in game design and development. A good game environment is a key factor in the process of game development and player experience. Procedural Content Generation (PCG) is currently a wide range of fully automatic game environment generation technology. This paper introduces some algorithms and experimental results of PCG for natural objects (such as vegetation, river, and terrain), with special attention to the applicability and aesthetic visualization. It is found that the appearance of PCG greatly reduces the time needed to design large-scale natural landscape for game levels. Furthermore, PCG is able to adjust the natural landscape in real time to improve the overall game development efficiency.
