AutoBiomes: procedural generation of multi-biome landscapes

Abstract

Advances in computer technology and increasing usage of computer graphics in a broad field of applications lead to rapidly rising demands regarding size and detail of virtual landscapes. Manually creating huge, realistic looking terrains and populating them densely with assets is an expensive and laborious task. In consequence, (semi-)automatic procedural terrain generation is a popular method to reduce the amount of manual work. However, such methods are usually highly specialized for certain terrain types and especially the procedural generation of landscapes composed of different biomes is a scarcely explored topic. We present a novel system, called AutoBiomes, which is capable of efficiently creating vast terrains with plausible biome distributions and therefore different spatial characteristics. The main idea is to combine several synthetic procedural terrain generation techniques with digital elevation models (DEMs) and a simplified climate simulation. Moreover, we include an easy-to-use asset placement component which creates complex multi-object distributions. Our system relies on a pipeline approach with a major focus on usability. Our results show that our system allows the fast creation of realistic looking terrains.

A Terrain Elevation Map Generation Method Based on Self-Attention Mechanism and Multifeature Sketch

“…This method can create large-scale terrain with less memory consumption and can implement special terrain. To solve the problem of less efficient manual editing, a semiautomatic procedural terrain generation method for terrain editing tasks has been proven to work [ 9 ].…”

Explaining autonomous drones: An XAI journey

“…COGLE's procedural generator draws on technical approaches developed for movie and video game industries to generate realistic artificial and imagined landscapes. Roland Fischer et al review 5 this technology. Figure 5 shows how COGLE's generator created and composed layers representing terrain, rainfall and water bodies, biomes and terrain types, roads, and buildings.…”

Improved Newton Iterative Algorithm for Fractal Art Graphic Design

“…is is a manifestation of the different understandings of fractal art research at home and abroad. Relevant scholars explained how Julia set, Mandelbrot set, and Newton fractal set adjust the number and shape of petals in clothing design and extracted texture information of different flower types, focusing on analyzing the relationship between Julia set flower types and various parameters [11]. Researchers proposed that works of art should represent nature and work like nature [12].…”
