@ Trafassel.
Very plant like.
I tried coding it into Mandelbulber, but my maths and programming was not good enough.
I noted with my attempted code below::
Line 3 -> x1 not used later.
Line 5 -> z.y = 0, then I cannot see it being given another value before being used later in the code to multiply.
code -> if(x2 * z.x < 0.0) spin=!spin;// I don't understand what is happening.
double power = fractal->bulb.power;
double phi = atan2(z.y, z.x);
double x1= z.x; // x1 ???? not used ------------------
z.x = cos(-phi) * z.x - sin(-phi) * z.y;
z.y = 0.0; // what???? -----------------------------------------
double theta = atan2(-z.z, -z.x);
if (fractal->transformCommon.functionEnabledFalse)
theta = theta + M_PI;
theta=(power - 1.0) * theta;
double x2 = z.x;
double re = cos(theta);
double im = sin(theta);
double a = re * z.x - im * z.z;
z.z = re * z.z + im * z.x;
z.x = a;
//if(x2 * z.x < 0.0) spin=!spin;// switch off spin ????---------
re = cos(power * phi);
im = sin(power * phi);
a = re * z.x - im * z.y; // line 5 above z.y = 0 ????--------
z.y = re * z.y + im * z.x;
z.x = a;
CVector3 z2 = z * z;
double r = z2.x + z2.y + z2.z;
r=pow( r, (power - 1.0) / 2.0);
z *=r;
z.y +=c.z; // axis swap
z.x +=c.x;
z.z +=c.y;
