| Abstract: | For the characteristics of multi-dimensional,multi-format,and dynamic with the marine environmental data,on the basis of comprehensive analysis on the NetCDF data model in principle,data organization,scheduling methods and so on,the paper designed a 3D dynamic rendering model for typical marine environmental data which follows NetCDF standards,implemented the representation and analysis of marine environmental data with three-dimensional and dynamic based on three-dimensional virtual scene.The experiment showed that the method of this paper could provide a powerful auxiliary tool for the representation of the complex ocean phenomena,spatial-temporal analysis and trend prediction. |
