Program ANRAYVRM
****************

   Program ANRAYVRM generates vrml files of 3-D images of the
model and rays from the files generated in the program ANRAY.
The program was compiled by Xuyao Zheng from the graphical software
used in the CRT package. The program ANRAYVRM consists of the main
program and four routines: VRML_INIT1.FOR, VRML_INIT2.for,
VVRML_LINE.FOR and VRML_SURFACE.FOR. The three last routines are
modified programs of CRT: INIWRL, LINWRL and SRFWRL, respectively.
For its proper work, the program needs the following routines from
the package FORMS: COLORS.FOR, ERROR.FOR, FORMS.FOR, LENGTH.FOR,
SEP.FOR, WRL.FOR, SEP.INC and RAM.INC. Before the run of the
program, the directory with the program must contain files with
names LUBRD.DAT, LUGRD.DAT, LUIND.DAT and LURAY.DAT, generated by the
program ANRAY. The directory must also contain history files
iniwrl.h, linbound.h, linray.h, srfwrl.h and files hsv.dat,
an-cam.dat, an-dli.dat and the file LIST, which contains the names
of the files generated in ANRAY. The program ANRAYVRM reads the
files automatically and generates a file 'anvrml*.wrl', where * stands
for successively generated numbers 01, 02,..
