thank you.  I was/am .. bowled over..  will render + examine hopefully this
weekend.
cheers.

Errata:
#declare FnScanner2 = function {pattern {object {Scanner}}}
make this
#declare FnScanner2 = function {pattern {object {Scanner2}}}

I just did a single frame at clock 0.75, and it seems like it ought to be fine.
  Might get to play with it more in a bit.

hi,

again sorry for the (relatively) long interval, RL..

interesting in that it made me think more about pattern(s).

I'm looking for a more .. colourful media interaction.  something like the
attached, but it really is crude.  my current understanding -- if that's the
word -- is that will take multiple densities combined.  lack of time is
a(nother) big problem right now.  anyway.  comments etc invited.


regards, jr.

No worries, my friend.  RL can be a real ass-kicker.

Sure - quick, easy, just showing you how fast a change or second color can be
added.

Well, I've already thought about that, and I've speculated on what you're trying
to do.

You can define different functions based upon the "space" the notes are
traveling through.
So you could have two spaces for FACE and EGBDF, or different colors for all of
the notes in the octave.  Or varying colors for where in the composition the
notes are, or their duration, or ....

Probably the best thing to do at the moment is describe as exactly what you want
to accomplish (including the parts that may be variable / adjusted) and that
would be the fastest way to puzzle out HOW to most efficiently get there from
here.

So, I finally had a chance to dabble with this a bit.
See what you think, and if this is going in the right direction.

I've got a media "staff" with some moving sphere "notes".
The media is colored according to the x,y,z values of the bozo pattern, and the
hue is detrmined by a set of functions that convert a value between 0-1 into a
set of rgb functions (my set of functions to do the equivalent of the CH2RGB
macro in colors.inc)

Crappy samples value to make the rendering faster...

50 frames, 5 frames per sec so you can actually see the coloration better.

Thanks  :)
It took me a little while, after a false-start, and a minor debugging or two,
trying to figure out how to get the (sort of) either-or result of select() to
work in a set of functions to divvy up the range into thirds.
After that it was pretty straightforward to copy the formulas in the macro.

Still wondering if this is in any way applicable to what you've done with the
RGB channels of the DF3 files.

Colour me green with envy. :)

I don't think so unless you want to do it the hard way. :)
