Abstract: In the field of meteorology, 3D storm data field visualization is one of the most important technical means of storm monitoring and disaster prediction. The visualization efficiency and quality directly affect the accuracy and timeliness of the analysis. Based on the study of the traditional 2D and 3D texture mapping methods, this paper proposes a multidimensional texture hybrid rendering method based on GPU for the storm data field. It uses 3D texture to storage storm data combined with dynamically generated of the geometry. It overcomes the problem of texture data redundancy and it ensures the fluency of 3D interactive. Texture mapping smooth resampling strategy is proposed to improve the 3D storm model display effects significantly and to avoid the CPU-GPU communication bottleneck.
