Automatic Generation of Multibiome Topography Based on Climate Modeling

The widespread use of computer graphics technology has inspired a massive demand for virtual landscapes in terms of scale and detail. Manually creating huge, realistic terrains with resource-intensive populations would be labor-intensive. Automated programmatic terrain generation has become a dominant method to reduce manual workload. For some terrain types, existing generation methods are usually highly specialized, but less work has been done on procedural generation of virtual landscapes under different eco-climatic conditions. In this paper, we propose an automated method for generating multi-biome terrain based on climate simulation, which can effectively create expansive terrain with reasonable ecological clouds and different spatial features. The proposed method integrates PCG (Procedural Content Generation) technology with DEM (Digital Elevation Model) and simplified climate simulation to model climate, vegetation, and topography, and ultimately generates ecological topography that can be used in the research fields of climate change, ecological environment, and natural resources. The experimental results show that the proposed method can quickly create ecologically realistic terrain.
