The underwater acoustics is primary and most effective method for underwater object detection and the complex underwater acoustics battlefield environment can be visually described by the three-dimensional(3D)energy field.Through solving the 3D propagation models,the traditional underwater acoustics volume data can be obtained,but it is large amount of calculation.In this paper,a novel modeling approach,which transforms two-dimensional(2D)wave equation into 2D space and optimizes energy loss propagation model,is proposed.In this way,the information for the obtained volume data will not be lost too much.At the same time,it can meet the requirements of data processing for the real-time visualization.In the process of volume rendering,3D texture mapping methods is used.The experimental results are evaluated on data size and frame rate,showing that our approach outperforms other approaches and the approach can achieve better results in real time and visual effects.
