Description

Technical Field

[0001] This invention relates to the field of computer simulation and virtual reality, and in particular to a three-dimensional space aircraft air combat simulation wargaming situation display technology. Background Technology

[0002] Air combat simulation wargaming is an important tool for conducting combat simulations, program evaluations, and tactical research. Traditional systems are mostly based on simplified static environment models, abstracting the battlefield environment into global parameters or fixed two-dimensional areas, which cannot realistically reflect the dynamic evolution and physical effects of extreme environments in three-dimensional space. This leads to serious distortions in tactical judgments. For example, it is impossible to dynamically determine radar detection range based on real electromagnetic field strength, to calculate the attenuation and obstruction of sensors and communications by complex weather conditions, and to accurately assess the impact of near-space on the maneuverability of hypersonic weapons, thus significantly reducing the reference value of the simulation results.

[0003] To overcome the limitations of static models, some systems have introduced the concepts of 3D visualization and dynamic environments. However, existing technologies still have the following problems: First, there is a serious disconnect between the environmental model and the core of the simulation. Most systems only achieve a three-dimensional "visual rendering" of the environment, and its dynamic, multi-layered physical data is not deeply involved in the core logical operations. Therefore, key tactical decisions still rely on simplified algorithms, failing to leverage the potential of high-fidelity environmental data.

[0004] Secondly, information display and understanding under extreme situations present challenges. High-density combat results in severe stacking of target icons in three-dimensional space, making it difficult for commanders to obtain a clear situational awareness. Simultaneously, how to intuitively demonstrate the impact of intangible environmental factors such as electromagnetic fields and probability clouds, while avoiding cognitive overload for users, is a major challenge currently faced.

[0005] Therefore, it is necessary to provide a new three-dimensional space aircraft air combat simulation wargaming situation display technology to solve the above-mentioned technical problems. Summary of the Invention
