Program notes for SAVERS.X screen saver program.
SAVERSX.EXE is a simple, completely algorithmic screen saver program.
It was basically undertaken as an experiment with the graphics capabilities
of Microsoft QuickBasic 4.5, and as a pleasant distraction from homework!
This program is distributed as freeware; no charge, no catches. I
only hope you may receive a bit of pleasure watching it play with your screen!
Comments, etc. may be directed to Robert Manning at (310) 373-3050. Please
let me know if you experience any problems with it.
Please note the monitor requirements on the main menu, and select
appropriately. I recommend using SAVERSX on a VGA-equipped system, with 512K
to 1MB video memory, and a 386 processor. A math coprocessor will speed things
up some. The program was developed on a 386DX-40 machine with 1MB video
memory. It has been tested on a 286 with EGA graphics, and a 486DX-25 with
VGA and small video memory, with no problems. However, selecting a saver
that requires VGA while using EGA graphics will cause an error and halt the
program.
The following is a brief description of each saver:
3-D Pillars:
A small 256-Color palette array is used to create a moving
set of "Pillars" which rotate across the screen.
Floating Pyramid:
VGA and two screen pages are used here to attempt to create
the illusion of a pyramid that floats and changes distance
from the viewer in space. This can be quite mesmerizing if
observed for a while. Video memory of 512K or better is best
for this saver, although it will work with less.
Night Moon:
This saver may look familiar! I attempted to create a nice
evening skyline, complete with a moon that sets. However, I
just had to add a few accessories... Several different things
happen to interrupt this quiet setting, wiping out parts of
the cityscape as they go! The cityscape will re-create itself
after a while.
Crazy Circles:
Just a bunch of colored circles running around the screen in
a repetitive pattern. Has a slight 3-D appearance as the
screen fills in.
Time Display:
An analog clock and digital readout show themselves here,
changing places and colors with each minute.
Trigonometry:
A QuickBasic drawing macro is used to form circles from
multiple triangles.
Pixels 'R' Us:
The simplest of the bunch, this saver lights up one pixel at
a time in multiple colors.
Moving Targets:
Concentric circles form these targets that change location
and size.
16 Color Prism:
This saver creates some very nice patterns using lines that
sweep around the screen. Best effect is had with the Color
Speed set to at least 20, and Color Interval at 3.
Palette Prism:
Basically same as the above saver, this version uses a 256
color palette array instead of the normal 16 colors.
Pressing [F11] will allow you to set a time delay factor to account
for varying computer speeds. This setting affects all savers except the Float-
ing Pyramid, which uses no delay. The effect varies a bit between each saver.
It will also allow you change the 16 Color Prism Color Speed (how fast the
program switches colors), and the 16 Color Prism Color Interval (how many
blank spaces between each line). The Palette Prism is also affected by the
Color Interval, but not by the Color Speed setting. The settings are saved in
a small file named SAVEDELA.Y. Make sure this file is present in the same
directory with SAVERSX.EXE before starting the program.
Well, that's it. I hope you enjoy this program! Comments will be
appreciated.
