FGDEMO version 1.0
-----------------------------------------------------------
FGDEMO: the demo program for Fastgraph and Fastgraph/Light
-----------------------------------------------------------
This program illustrates some of the features of the Fastgraph (tm)
graphics library. It was written by Diana Gruber, senior programmer at
Ted Gruber Software. You can contact Ted Gruber Software at the address
and phone numbers listed at the bottom of this file.
FGDEMO is distributed with source code. It was originally compiled with
the Microsoft C 5.1 medium memory model. You may use the source code in
FGDEMO in your own applications. This program requires either Fastgraph
or Fastgraph/Light (tm) to link. If you want to use this code, and you
don't have a copy of Fastgraph, please contact Ted Gruber Software.
---------------
Starting FGDEMO
---------------
You can install FGDEMO on a hard disk or run it from diskette. Just type
FGDEMO at the DOS command prompt. To install FGDEMO on a hard disk,
create a subdirectory and copy all the files from the diskette to the
subdirectory.
-----------
Video modes
-----------
FGDEMO runs in a choice of 4 video modes:
640x200 2-color CGA
640x200 16-color EGA
640x350 16-color EGA
720x348 Hercules monochrome
When you start the program, you will be given a default video mode choice,
and an opportunity to change to one of the other video modes. We suggest
you try all of them, and see what they look like. Note that some of
these video modes may not be available on your system.
--------------
Running FGDEMO
--------------
After you start FGDEMO and choose a video mode, an attractive horizontal
menu bar will appear at the top of the screen. Press any key or click
the left mouse button to get the first pull-down vertical menu. Select a
feature from this or any menu. The menus are intuitive. Select and try
all the features on all the menus.
-------------------
Distributing FGDEMO
-------------------
You may freely distribute FGDEMO as long as all the files are distributed
together in their original unaltered state. If you want to zip the files
together for BBS distribution, please use the file name FGDEMO10.ZIP for
version 1.0 of FGDEMO. The following files are included in the FGDEMO
distribution:

Make files
----------
BUILD BAT - batch file to compile and link FGDEMO with Turbo C
FGDEMO PRJ - project make file for Turbo C
WORK - make file for Microsoft C
----------------------------
Compiling and linking FGDEMO
----------------------------
The source code files may be recompiled using either Microsoft C or Turbo
C. The medium memory model is recommended, and the large model will also
work. FGDEMO is too big to use the small memory model.
If you are using Microsoft C, use the make file WORK to compile and link
FGDEMO with the Fastgraph/Light medium model library. If you want to
link FGDEMO with Fastgraph instead of Fastgraph/Light, change the library
name FGLM to FGM in the LINK command.
If you are using Turbo C, Turbo C++, or Borland C++, use the project make
file FGDEMO.PRJ to compile and link FGDEMO. Be sure you've configured
the compiler to use the medium memory model. Alternatively, you can use
the command file BUILD.BAT to perform the compilation and linking.
BUILD.BAT uses the TCC command; you may need to change it for Turbo C++
or Borland C++. If you want to link FGDEMO with Fastgraph instead of
Fastgraph/Light, change the library name FGLM to FGM in the TLINK
command, or in the last line of the project make file.
You may have trouble running FGDEMO in the 640x200x16 color mode in the
Turbo C integrated development environment. That is because the
environment allocates all available memory, making it impossible for
Fastgraph to allocate a virtual video page. FGDEMO requires two video
pages. You should be able to run FGDEMO in the other video modes, and
you should have no trouble compiling, linking, and running FGDEMO from
the DOS command line.
We have had some reports of trouble with older versions of TLINK finding
the Fastgraph or Fastgraph/Light libraries. If you have this problem, be
sure the full path name of the library appears in your TLINK.CFG file. If
that does not solve the problem, include the full library path name in
the TLINK command. We called Borland technical support about this
problem, and they told us there is no TLINK.CFG file supported in Turbo C
version 2.0, but it is supported in Turbo C++ and Borland C++.
----------------------
About the FGDEMO menus
----------------------
The menu structure is defined in the file DEFS.H. A typdef CMD is
defined which is a structure containing information about each menu
item: the function called when the menu choice is activated, the
descriptive name of the menu item, the x and y location of the menu item,
and pointers to the next and previous items on the menu. Each menu is
defined by an array of these structures, and is initialized at the top of
MENU.C.
There are two types of menus: a horizontal menu, which is the moving bar
menu at the top of the screen, and vertical menus, also known as
"pull-down" menus. When a pull-down menu is visible, a menu function may
be activated by either clicking the mouse on a highlighted menu function,
or by pressing <Enter>. Arrow keys are used to highlight the next and
previous menu item, and a mouse may also be used.
User input relevant to the menus is accepted in two places: within the
vertical_menu function (to activate a menu choice), or in the main
function (to control the horizontal menu). The horizontal menu is also
controlled within the vertical menu, to the extent that if an arrow key
is pressed, the next or previous pull-down menu becomes active.
The entire screen, including the horizontal menu and the dithered
background, is drawn at the beginning of the program and stored on the
hidden page. When a function is called, for example "point", part or all
of the visual page is overwritten, in this case with a pattern of
points. When a key or mouse button is pressed, the relevant parts of the
hidden page are copied back to the visual page using fg_transfer,
resulting in quick (almost instantaneous) screen redraws. Occasionally,
the entire hidden page needs to be completely redrawn, such as after the
graphics file is displayed, but in most cases only a small part of the
hidden page needs to be redrawn, usually with a single call to fg_drect.
In general, the hidden page is assumed to have a "clean" copy of the
horizontal menu screen throughout the program, and whenever it is
overwritten it is immediately restored.

About Fastgraph
---------------
Fastgraph is a professional graphics library of more than 150
highly-optimized routines that are callable from high-level and assembly
language programs running under the MS-DOS or PC-DOS operating systems.
This collection of routines provides a programmer with proven, powerful
tools to take command of the PC and PS/2 text and graphics video
environment. Fastgraph/Light's major features include:
* Video mode detection and initialization
* Colors, virtual colors, and palettes
* Graphics fundamentals, including points, solid and dashed lines,
polygons, circles, ellipses, solid and dithered rectangles, region
fill, and clipping
* Character display
* Image display facilities, including mode-specific and mode-independent
images, clipped and reversed images, image retrieval, pixel run maps,
and image transfer
* Screen space, character space, and programmer-defined world space
coordinate systems
* Physical and virtual video page management
* Animation
* Special effects
* Keyboard, mouse, and joystick control
* Sound effects and music, both synchronous and asynchronous
* Supports Microsoft C, Turbo C/C++, Borland C++, QuickC, QuickBASIC,
and MS FORTRAN
* Supports small, medium, and large memory models
* Extensive tutorial-style user's guide and reference manual
* No royalties
As its name implies, the most notable feature of Fastgraph is its speed.
Fastgraph is written in 8086 assembly language, and each routine has been
optimized by hand to provide maximum performance.
Fastgraph supports all standard text and graphics video modes used by the
IBM PC (PC, PC/XT, and PC/AT) and PS/2 families and compatible systems.
In addition, Fastgraph/Light provides support for a commonly used video
mode for the Tandy 1000 series computers and the PCjr, two video modes
for the Hercules Graphics Card, and two extended VGA modes.
Fastgraph is an ideal development tool for entertainment and educational
software, presentation graphics products, scientific and engineering
applications, CAD/CAM, animation, or any application that requires robust
graphics. Fastgraph has been used in retail products such as Accolade's
Test Drive III, Day of the Viper, Steel Thunder, and Gunboat,
ComputerEasy's Video Poker a la Carte, Compu-Teach's Once Upon a Time
series, Destination: Mars, and Puppet Playhouse, and all our shareware
products.
