The confusion came from the fact that my formula has a different setting, that makes tricky to find variations;
I really wanted to make Buffalo variation the default one, so I assigned the number zero to it! But I just forgot
Oh well
In my opinion the very best buffalo is the one that multiplies z and y by a negative number (not positive)
It's not eassy to tune perfectly a variation because many variations are available
By the way the only one that is a Buffalo in xy and xz section is something like
{
double x2 = z.x * z.x;
double y2 = z.y * z.y;
double z2 = z.z * z.z;
double temp = 1.0 - z2 / (x2 + y2);
double newx = (x2 - y2) * temp;
double newy =
-2.0 * z.x * z.y * temp;
double newz =
-2.0 * z.z * sqrt(x2 + y2);
z.x = AddCCondit(newx, c.x, j); shr (j,2);
z.y = AddCCondit(newy, c.y, j); shr (j,2);
z.z = AddCCondit(newz, c.z, j);
}
When jj = 010101b = 21d using my convention
This is not true for just any variation, some look great only when all variables are positive
(edit!!! Lied - this particular variant doesn't care of signs
- all good)
