The three-dimensional visualization is indispensable in order to understand three-dimensional simulation results such as the earth's magnetosphere better. By the appearance of the VRML (Virtual Reality Modeling Language) which is the international and standard language for the internet's three-dimensional visualization, it would be possible to watch the three-dimensional image as VRML file by the VRML viewer, even if people does not have three-dimensional image processing machinery a nd three-dimensional image processing software. It is shown the method of how to make VRML file by fortran and example and interface subroutine package of making for the VRML contents preparation.
