i would like to write plasma demo using sin table as i have not done
something like this before. i would like to use it as a visual plugin
to my mp3 player.
i have searched all of google and have yet to find a decent tutorial
on how to write a 'sin' based plasma demo. if any of you can help that
would be great.
moving on i gather the plasma is created as a result of adding
multiple sin equations together and using that as the color index or
do 3 separate ones to get values for RGB.
my question by using the sin table sometimes the index value can be
negative (0 to 360 angle)! how do i avoid this? do i just cache the sin table with the
positive value region of sin?
thanks in advance,
