A Method of Optimizing Terrain Rendering Using Digital Terrain Analysis [PDF]
ISPRS International Journal of Geo-Information, 2021 Terrain rendering is an important issue in Geographic Information Systems and other fields. During large-scale, real-time terrain rendering, complex terrain structure and an increasing amount of data decrease the smoothness of terrain rendering. Existing

Orometry-based terrain analysis and synthesis [PDF]
ACM Transactions on Graphics, 2019 Mountainous digital terrains are an important element of many virtual environments and find application in games, film, simulation and training. Unfortunately, while existing synthesis methods produce locally plausible results they often fail to respect global structure.

Analysis of terrain navigability in underwater terrain aided navigation [PDF]
Journal of Physics: Conference Series, 2021 Abstract Aiming at the problem that the single terrain characteristic parameter cannot comprehensively evaluate the terrain navigability of the matching areas, the weighted vector correlation degree is introduced, and the terrain characteristic parameters such as the standard deviation of terrain elevation, roughness, correlation ...
