This little graphics "Thingy" has been provided by "IMPULSE"
(formerly Genesys Technologies). The author is in the process
of completing "Sky Chase" a real time air combat game using
his fast 3D drawing routines. Ralph Russell initially wrote the
game for the now defunct "MindSet" computer. We think the game
will be a REAL KILLER! We expect to begin shipping "Sky Chase"
in early summer of 87. In the meantime, I will periodically
upload various routines and demos related to the game.
To really appreciate this demo you should have 2 Joysticks connected
to your Amiga. Joystick 1 controls the actual view window, and
Joystick 2 controls the Logo. There is no gravity but the
Joytick buttons do accelerate each function with proper inertia
claculated properly, so you can "fly" around, over, and through
the LOGO in realtime. These demos as well as the actualgame
are written in Amiga Assembly. This particular demo was
written using proprietary routines, which are actually 1 fps
faster than the Amiga Blitter can do!

SKYCHASE by RALPH RUSSELL 01/87
This program will display the logo for a game I am developing in
3D space in front of the viewer. Two joysticks should be used to
experience this program properly. One joystick controls the position
of the logo and the other will control the position of the viewer.
The joystick buttons are used to accelerate the logo and viewpoint.
You can fly right through the logo if desired. All rotation, scaling,
translation, and line drawing is done in real time. Maximum speed
is attained by using certain advanced features of the AMIGA plus
highly optimized code written in assembly language.
This program takes complete control of the AMIGA and the system must be
booted to terminate the program. Therefore, it should not be run when
a ram disk is active. Also, even though the program is small, it uses
a lot of memory (191K plus 96K for a tripple buffered display). The
program was written and tested on a 512K machine and I don't know if
it will run on a machine with more memory.
This is a public domain program and is not to be sold for profit.
You may make copies of this program to be given away for free. It is
my wish that anyone receiving a copy of this program should also receive
a copy of this file you are reading.
