As we known, the virtual reality simulation technology of true ocean environment was one of the most important
research fields in visual simulation technology. Firstly, the ocean geographic environment information from 2-dimension
electronic chart was extracted directly; the information was the data basement of virtual ocean environment visual
simulation. Second, on the basis of studied the environment modeling technology and constitution of three dimension
ocean environment model systematically, using the 3-D digital map modeling Delaunay algorithm for environment
modeling, then the 3-D landform DEM data was translated into the DED file which could serve for the data of 3-D
landform modeling. At last, this paper shows the realization of 3-D virtual ocean environment base on true ocean
information, which achieved living simulation result, and improve the whole level of view simulation.
