Research on Natural Scene and Meteorological Environment in Virtual Rebuilding of the Prehistoric Settlement Sites

Based on the data of Jiangzhai one-stage settlement sites archaeological excavation data, this paper applies three-dimensional visualization technology of virtual reality to scenario building. In order to enhance the fidelity of prehistoric settlement sites to reproduce the virtual system simulation results in the system design and implementation process, it essential to build plenty of the natural environment and weather environment scene. Time and user input as the driving source to realize the sky and the surface changing with the time of seasons and weather changes in the environment. The texture mapping technology, Billboard, LOD and Particle Systems are also used in the reconstruction of trees, mountains, and meteorological elements, such as snow sleet. To generate a vivid model of the scene of the prehistoric settlement site, and the life of the primitive settlement has been reproduced.
