在气象领域，三维风暴数据场可视化是风暴监测及灾害预测的重要技术手段之一。可视化效率及质量直接影响到风暴体分析研究的准确性和时效性。针对传统的二维、三维纹理映射体绘制方法进行了研究，提出了一种基于GPU的风暴数据场多维纹理混合绘制技术。该方法采用了三维纹理存储风暴数据场并结合代理几何体动态生成方法，克服了传统方法中纹理数据冗余的问题，并保证了模型的三维交互流畅性。该方法中提出的纹理映射光滑重采样策略，显著提高了风暴体模型显示效果，并在一定程度上避免了CPU-GPU通信瓶颈。

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 timeli-ness of the analysis. Based on the study of the traditional 2D and 3D texture mapping methods, this paper proposes a mul-tidimensional 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.
