Implementation of Valley Simulation System Based on Virtual Reality Technology

Abstract

Abstract: A valley simulation system is developed based on Multigen-CreatorPro and Vega. Through a 3D models built on DEM data and ETM+Image data, this paper implements a valley simulation system on MFC in Guanting and Miyun reservoir area, realizes the system function, andexplores the technology detail of level of detail, multi-thread, virtual texture. By implementation of a real-time interactive 3D valley terrainsimulation environment, it approaches a solution of building valley simulation system.
