基于OSG 的三维仿真编辑系统

o build a Scenario-based modeling roaming and simulation systems,user usually use hand-built software to construct three-dimensional scene,then import it into the roaming system,which can saves user\\\\\\\??s time and costs. This paper introduces a three-dimensional simulation edit system based on OpenSceneGraph,which is a kind of open source graphics engine,and it focus on the methods of building scenario and scenario optimization strategy used in the edit system.Then it introduces of the function module of the edit system, and demonstrated an earthquake disaster relief training simulation produced by the edit system.
