** SCAPE.PRG Version 1.2 ***
scape.prg creates random planetary space scenes. Just run the program
and see for yourself. The following keys are available after the Bell
tone is heard. The bell tone indicates picture drawing or saving has
completed. But you will only have about 45 seconds to react before the
next plot is started.
<ENTER> : Bypasses wait delay and starts new plot.
<ESC> : Returns you to the desktop.
<SPACE> : Hold picture in place for viewing. Press any key again
releases hold.
'P' or 'p': Saves the plot to a PCX file. This means you will need
GEMview or some other program that will display MSDOS
paintbrush files. Warning filenaming is internaly created
and a count sequence is maintained. Exiting and restarting
program resets the count and will result in overwriting
previous saves. Rename or move saved file before starting
program. When picture save is completed a bell tone will
be issued.
'G' or 'g': Same conditions as above but saves picture in GIF format.
System Requirements:
A video mode that will display 256 colors. Sorry But I didnt write
the software. Perhaps I will modify the code to use 16 color grayscale
if there is enough interest.
Program types:
scape881.prg - Need's 68020 or better with 68881/2 co-processor. Uses
direct video memory access for ploting.
scape.prg - Need's 68000 or better. Uses direct video memory access.
scapevdi.prg - Need's 68000 or better. Slower then snails, but included
for third party video hardware.
History:
Version 1.2 - Added GIF code. Reset wait timer after pic save. This should
give you time to exit before the next picture is started.
1.1 - Fixed displayed colors. Saved to picture file correctly. But
didnt display them correctly.
1.0 - PC version ported to the ST.
The source code is available in the publication "Tricks of the Graphics
Gurus". SAMS Publishing ISBN 0-672-30308-6. ST part of source code
