摘要
直接绘制展示复杂的电磁环境能够辅助指挥员直观、形象的理解电磁态势。在CUDA架构下使用直接体绘制的方法实时绘制动态电磁环境:数据生成和更新均在CUDA架构下并行计算完成,采用设备有效值计算减少计算和更新数据的时间;针对数据的一致性特点,使用CUDA架构实现并行光线投射算法对绑定到三维纹理的数据场进行绘制,绘制的同时允许实时交互调整观察视角。实验结果表明,从数据计算、更新到绘制使用CUDA架构进行加速能够对动态电磁环境进行实时绘制,绘制结果较好的展示了电磁态势的动态分布,同时可以实时交互调整观察视角。
Rendering and displaying the complex Electromagnetic environment is helpful for the commanders to understand the electromagnetic situation. The real-time rendering for the dynamic electromagnetic environment was carded out under CUDA. To improve the speed of computing and updating data, parallel computing the specific range volume data was employed. Based on the data consistency, CUDA was used to carry out parallel ray casting algorithm for rendering the volume data which were bound to the 3D texture, and the viewpoint was able to change when rendering. Experiments demonstrate that using CUDA can render the dynamic electromagnetic environment volume data in real-time. The rendering distributes the electromagnetic situation well and meets the requirement of real-time interaction.
