Abstract
Systems, methods, devices, and non-transitory media of the various embodiments may include encoding localized terrain modifications into one or more heightmaps, which are used to modify the vertices of the world-wide terrain map at runtime using a Graphics Processing Unit (GPU). Various embodiments apply displacement to dynamic terrain surfaces, such as time dynamic surfaces, animated surfaces, Hierarchical Level-of-Detail (HLOD) surfaces, and surfaces suitable for interactive user editing, at a global scale.
