  We will present the VRML (Virtual Reality Modeling Language) 
Fortran main program for 3-dimensional visualization and the 
subroutine package to run the main programs.


(1) Main VRML Fortran Programs

1.mcube301.f  : 3-dimensional iso-surface plot
                csuba(ic,aa,u) 
2.mface015.f  : draw 2-dimensional surface using color code
                image1(nx,ny,xb,yb,xl,yl,ico,icc,zcc,u,p) 
3.mlineb33.f  : 3-dimensional line plot with many points
                line3d(lasl,r,g,b,po)
4.mpixe015.f  : 2-dimensional pixel image plot
                pixel2(nx,ny,xb,yb,xl,yl,ipx0,ico,icc,zcc,u)
5.mpoint13.f  : 3-dimensional point plot
                point3d(nx,ny,nz,x0,y0,z0,xl,yl,zl,ico,u)
6.mtriangm.f  : 3-dimensional triangular mesh
                triangm(nx,ny,u,p)
7.mzpt03.f    : pixel image
                pixel2(nx,ny,xb,yb,xl,yl,ipx0,ico,icc,zcc,u)

(2) Subroutine Package

8.zvrsuba.f
  All the Fortran subroutines which are needed in the main 
programs are arranged in this subroutine package.


<How to use the VRML Fortran main program and subroutine package>

  f77 -c -O zvrsuba.f  : make object module, zvrsuba.o
  f77 -O mcube301.f zvrsuba.o
  a.out &  : fort.10 for output VRML file is produced
  mv fort.10 mcube301.wrl

VRML 2.0 file can be seen by proper VRML viewer like "cosmoplayer".
