US$11.zip plots 3D surfaces on the PC screen. V. 1.1.
Copyright Gleb Vdovine, December 1993.
US$11 is a simple program to plot a pseudo 3D "surface" on the
screen of a personal computer. Usage: US$11 <filename>. Data
points Z(x,y) should be calculated or measured in the knots of
UNIFORM rectangular grid with dimensions (1..NX, 1..NY). As the
grid is uniform, the only coordinate information we need to make
a graph is the X and Y dimensions NX and NY. So the input file
should has the form:
NX NY ! data dimensions
Z(X1,y1) ! first Z value of first X row
Z(X2,y1) ! second Z value of first X row
......
......
Z(NX,y1)
Z(X1,y2) ! first Z value of second X row
.......
Z(NX,y2)
.......
Z(X1,NY) ! first Z value of last (NY) X row
.......
Z(NX,NY) ! last Z value of last (NY) X row
EOF
You may find the examples of input in files:

example1
sinxy.dat
The main application of US$11 is a fast "viewing" of
the results of two-dimensinal calculations. Of course the scale
factors on X and Y axis in most cases will be distorted with the
program, as it shows all graphs with more or less equal length
of X and Y sides. Angle of view is also fixed.
To fabricate a data file for the program, you must first write
down the integer dimensions of your graph and then write (or
print and then redirect) the results of your calculations from
inside of two nested loops. Optimal dimensions of input file are
NX*NY=[40....80]*[40....80]. Program was tested with NX=NY=100-
file sinxy.dat is 100*100 data file. NX>100 or NY > 100 may
cause problems with memory allocation or other problems.
File sinxy.dat has been generated with an example program
SINXY.EXE, text of which SINXY.FOR is written in FORTRAN just to
show how simply the input file may be formed. Output of
SINXY.EXE has been redirected to file SINXY.DAT with a command
SINXY.EXE > SINXY.DAT.
Program works well with different graphic cards, it was tested
with EGA, VGA and HERCULES. Please keep the *.bgi files in the
working directory !
Output image may be printed with PrtScrn (on some computers and
with some printers). A bit better way is to grab image with a
screen grabber and than edit it (if necessary) with a bitmap
graphic editor. Grabbers for different graphics cards are
available via FTP as well as with some commercial programs. For
example GRAB.COM which makes WPG copy of a screen image is
supplied with WORD PERFECT.

REGISTERING.
If You use US$11 and find it useful (?!), than you can register
it by filling in the register form and sending it with a
contribution of US$11,- or more, to

Please note
! Cheques must be made payable to Gleb Vdovine
! Payment may be made by sending cash in an envelope (Use
registered mail) or by sending a Eurocheque (in Europe). If you
send a cheque other than a Eurocheque, add US$ 5 (then you get
US$16),- for bank charges.
When you register, you get a registered copy with the next features:
* silent
* another viewing algorithm
* support of different formats of input data
* new features asked by other people who registered it
* my infinite thanks
If you keep using this program, but do not want to register it,
would you be so kind to send me a picture postcard of your town,
village etc. with an (original) post stamp on it.
* Ideas, hints, remarks, comments etc.
If you have a something to ask about US$11- for example if you are
tired of Russian music (:-), please don't hesitate and let me know.
