i am looking into the equation that creates the butterfly.
if you have a matrix 30x40
then i do a loop x= 0 to 29
y = 0 to 39
f(x,y) = butterfly()
values of zero and one (bottom left corner of a matrix, are always returning a zero. The return value is the hue. A hue of Zero is RED.
in other words, i need to find why 0,0 or 0,1 and 1,0 always have the equation return 0.
i am looking in to it. I wrote the equation two years ago and have not delved deeper.
this is where i found the original equation, http://mathworld.wolfram.com/ButterflyFunction.html
