In order to reflect more vivid details of attack and defense of surface warfare scene simulation such as missile launch, missile hit, gun fire, radar search and decoy expand, several key technologies including system designing, component-based modeling, component-based model-driven were researched. A component-based modeling method was proposed which combined multi-granularity modeling and sub-model replace. This method could load component-based model dynamically by list configuring and memory mapping. The component-based surface warfare scene simulation system designed as a federate of a large distributed surface warfare simulation system federation could receive data of the corresponding federate such as missile, artillery, radar and jamming system, and then the component-based model in the 3D scene was driven.

In the past, the visual describing of acoustic beam mostly based on 2D plane, and the method could not describe the shape and dynamic effects of acoustic beam in the underwater space. In order to describe the acoustic beam in 3D visualization, a realization method was proposed based on the method named data field isosurface drawing Marching Tetrahedral. According to the acoustic beam equation, the shape of the acoustic beam in underwater space, single beam scan and multi beams search was drawn. Through optimizing the space subdivision, it was ensured the 3D visual acoustic beam could be real-time in scene simulation. The realization effect indicates the vision effect of this 3D acoustic beam is real and fluent, and has provided more intuitional scene. Source
