针对海洋环境数据多维、多格式及动态性等特点,本文在全面分析NetCDF数据模型的原理、数据组织及其调度方法的基础上,基于大范围三维虚拟场景,设计了符合NetCDF标准典型海洋环境要素的三维动态渲染模型,实现了海洋环境要素数据的三维动态可视化表达与分析。实验表明,本文方法为复杂海洋现象的表达、变化规律分析以及趋势预测等研究提供强有力的可视化辅助工具。 According to the multidimensional, multi-format and dynamic characteristics of marine environment data, this paper, based on a comprehensive analysis of the principle, data organization and scheduling methods of the NetCDF data model, based on the large-scale three-dimensional virtual scene, Dimensional dynamic rendering model to realize the three-dimensional dynamic visual expression and analysis of marine environmental factor data. Experiments show that the proposed method provides powerful visual aids for the study of complex ocean phenomena such as the expression, change rule analysis and trend forecasting.
