Virtual Battlefield Environment The Key Technologies Of 3d Visualization And Realization

As a kind of special geographical environment, the 3D visualization of virtual battle environment(VBE) is always a difficult and essential problem in the field of the virtual geographical environment. At the base on the deep research about the virtual battle environment and the integration about the realization technology of the 3D visualization in GIS field, this thesis argues how to set up a 3D visual system of virtual battle environment simulative opposition at the unit level in detail. The system describes the battle scene between the Red(attack) and the Blue(defense) in the designed hills ground form area.The thesis mainly discusses the realization methods and progresses of the visualization part of the system. Because of the limitation of the geographical area and the number of the armament, we can see the variety of the situation of the weapons and the soldiers clearly in the process of the battle. At the same time, the system not only simulates the fog on the ground, but also uses particles system to realize the description of the smog and rainfall in the VBE, in order to getting more proper for fight simulation. Except for the effect of launching and exploding, and after exploding, crater on the ground will also appear. The system has also added the artificial sound which makes the scene of the battle more vivid.The thesis makes a summary about the key technique of the virtual battle environment and discusses the system analysis of the 3D visual system of virtual battle environment simulative opposition at the unit level in terms of software project.
