Synthesizing realistic detailed geometric models of terrains is an open problem in computer graphics. Terrain models are intrinsic in virtual scenes and the human visual system is well-equipped to see imperfections and irregularities. Therefore, authoring the geometry of the inhomogeneous terrain structures is both important and difficult. This problem is further exacerbated by the environment that is the principal geomorphological agent and affects the terrains at varying scales and temporal ranges. This presentation will cover recent advanced in terrain modeling in computer graphics. After a brief introduction of terrain models and the commonly-used data structures that represent them, we will focus on advances in 1) procedural modeling, 2) simulations, and 3) example-based synthesis.
