This paper develops large scale marine hydrological environmental data-oriented visualization software and realizes oceanographic planar graph, contour line rendering, isosurface rendering, factor field volume rendering and dynamic simulation of current field.

This study establishes nodes in the scene for the management of geometric objects to realize high-performance dynamic rendering of massive marine hydrological environmental data.

The system employs CUDA parallel computing to improve the computation rate of volume rendering of marine water environmental factors based on NetCDF (Network Common Data Form) format.

The visualization software of marine hydrological environment developed can simulate and show properties and change process of marine water environmental factors efficiently and intuitively.
