Three Dimensional Visualization Using VRML

1. Name of Database:　 Three Dimensional Visualization Using VRML

2. Institution:　Solar-Terrestrial Environment Laboratory, Nagoya University

3. Contents of Database:

This database presents the method of three dimensional visualization to use VRML 
(Virtual Reality Modeling Language) by Fortran and C language, and many examples 
of 3-dimensional visualization obtained from the computer simulation of the solar 
wind-magnetosphere interaction.

Three-dimensional visualization is indispensable in order to understand 3-dimensional 
simulation results such as the earth's magnetosphere better. By appearance of the VRML 
which is only the international standard language for the Internet's 3-dimensional 
visualization, it would be possible to watch the 3-dimensional image as VRML file by 
the VRML viewer, even if people does not have 3-dimensional image processing special 
computers and 3-dimensional image processing special software. However, utilization 
and popularization of the VRML do not advance very much in present state, because there 
is no a convenient tool which easily makes the VRML file and also it is not easy to make 
the complicated VRML file.

In order to develop the method for visualizing 3-dimensional simulation result of the 
magnetosphere by using the VRML, we have wrestled in making the VRML file earlier by 
utilizing experience and knowledge cultivated for a long time for the image processing 
using Fortran and C language. In the computer science and technology project as the extension, 
we have made this manual "How to Use VRML" for the purpose of the 3-dimensional visualization 
of the simulation results by presenting interface subroutine packages for the VRML contents 
preparation by Fortran and C language.

This database presents all main Fortran programs and subroutine packages shown in this manual 
as a source program format and demonstrates many examples of 3-dimensional visualization 
obtained from the computer simulation of the solar wind-magnetosphere interaction. 
We are happy if it is useful for the simulation and data analysis scientists.

the shock wave arrival, which was obtained from 3-dimensional MHD simulation of 
the solar wind-magnetosphere interaction.
