bits 93
Hi all, here's a little demo I did a couple of days. It is part of a
suite of programs written for Fresh week 1993 for Bits - The University
of Bristol Computer Society (of which I am President).
It was written in 2 days from scratch and so is not as optimised as it
perhaps should be. It demonstrates a multi-coloured sine-wave scroll text
scrolling over a static background with a 'lens' effect bouncing over
the top of them both.
It was written on a 33MHz 486 with a Paradise 90c30 graphics chipset on
an 11MHz bus. If you run it on anything less, then don't blame me if it
either doesn't work, or goes horribly slowly! If you machine isn't
fast enough, then it will probably all flicker horribly as I haven't
used double buffering (tut tut).
I have included the full source code for this demo. Please feel free to
examine it. I apologise in advance for the lack of comments, and the
code may be hard to follow simply because it has been optimised. If you
find the code useful, a greet would be appreciated in any demo you write.
Please don't just blatently rip it off.
The program is designed to be compiled using Turbo Assabler (TASM).
You may or may not have problems trying to recompile it under anything
else. If you want to alter the text or change the lense effect, then
you will also need GWBASIC to redo the tables.
I am currently seeking to join a demo group of some description
(preferably one with a good musician/graphics artist) - email me if you
are interested.
