this software is intended as the basis for a newer and commercial vlm. so
the current vlm may be seen as a free preview.
----------------------------------------------------------------------------
system requirements
----------------------------------------------------------------------------
the requirements:
atari falcon, 14 megs, rgb or vga
recommended (for anything more than whip plugins):
tt ram, 50 mhz cpu at least, preferably a 060.
for instance a ct2 system, but even better a ct60.
(hey, at least you don't need fpu ;))
----------------------------------------------------------------------------
features
----------------------------------------------------------------------------
the ct60 vlm is quite normal. it compares to whip and is (partially)
compatible with this program. the goal is to make a vlm that has most whip
features, but in terms of visuals compares to i-tunes (mac) or some 2d
plugins in winamp (windows), for instance geiss.dll.
it can take input from the mic, the good ole yammy and possibly even sdma.
desktracker or paula, anyone? you can even configure the falcon's matrix
to have yammy on left and mic on right for some fun ;)
also, the idea is to have channeling and mixing of multiple plugins
simultaniously and live control and sequencing features, but this is still
to be done.
----------------------------------------------------------------------------
usage
----------------------------------------------------------------------------
the main program is 'shell.gtp'. just drag a '.vlm' plugin file onto it and
watch. you can ofcourse also just run it and then enter a plugin name. the
vlm eats both traditional 'whip!' plugins, but doesn't always like them.
also note that whip plugins grab the whole system and there still are some
incompatibilities.
to get decent sound input, use the fsnd.cpx by tom noorduin, which is
supplied with this package. fiddle a bit with adc l/r gain and mic/psg
selection on l/r to get the settings you prefer.
the most important feature of this vlm is not its ability to run the whip
plugins, but to run a newer type of plugin. such plugins offer stuff like
alpha layers, channeling, are multitasking friendly and in newer version
may even be viewed in a window or scaled in real-time.
if you're brave enough you can enter an apx (apex block) file as second
parameter. this should be a 8 bpp file and of not too big proportions. yep,
now you got a backdrop alpha layer. =) with the numpad's '-' and '+' keys
you can control the alpha. the alpha ofcourse works only with new plugins.
when you're bored with a plugin just hit space.
the following plugins are bundled:
collido.vlm an old whip plugin by me, nice and psychy
geissvir.vlm an attempt to recreate the geiss pc thing. reasonably
succesful. runs okay on ct2, flies on ct60.
galaxy.vlm a rather sad attempt at a fluffy galaxy, use a ct60 pls
lissajou.vlm a simple, but effective plugin that looks very nice with
all kinds of music. soft music = smooth shapes, hard music
= harsh shapes
radial.vlm yeps, a radial blur again. at least no cube or tunnel ;)
----------------------------------------------------------------------------
history
----------------------------------------------------------------------------
- v0.1, sept 2004:
most basic functions: scopes, spectra, volume, alpha background,
virtual 8 bit chunky mode
- v0.2, jan 2005:
bugfix: ugly stripes removed by improved vbl handling
locking function: press 'h' to lock a particular sub effect in a plugin.
for instance, the geissvir.vlm plugin supports this.

bugs and ideas
----------------------------------------------------------------------------
if you notice something odd, send a bug report with complete system config
(os, rgb/vga, accelerator type, etc).
also, feel free to send any ideas you may have to improve the quality of
this free software.
----------------------------------------------------------------------------
programming
----------------------------------------------------------------------------
it is very easy to code a plugin for this vlm and loads of housekeeping is
done automatically. you don't need buffering, syncing to vbl or even c2p.
it's all built in!
just for fun, the geiss plugins source code is supplied, so you can try
to hack toghether some of your own plugins.
----------------------------------------------------------------------------
finally
----------------------------------------------------------------------------
have fun! =)
