摘要
为实现全球视角下高分辨率海洋标量场的高效、全域三维动态可视化,提出了一种基于web的数据动态可视化方法,设计了一个大屏展示的可视化平台。平台采用分布式架构,引入新的时变数据组织方法去除冗余数据;设置人眼色差识别阈值减少渲染数据量;准确定位渲染命令,利用GPU渲染技术,实现高效实时渲染。结果表明,所设计的时变数据组织方法可以减少时变渲染所需时间,提高海洋数据可视化系统全域渲染的分辨率和速率。
A web-based data dynamic visualization method was proposed to realize high-resolution 3D dynamic visualization of ocean scalar fields from a global perspective.The visualization platform for large screen display adopted distributed architecture and introduced a new time-varying data organization method to remove redundant data.The human eye color difference recognition threshold was setted to reduce the amount of rendering data.The rendering command was accurately located,and the efficient real-time rendering was realized by GPU rendering technology.The results show that the time-varying data organization method can reduce the time needed for time-varying rendering and improve the resolution and speed of global rendering.
