Title: Storm is coming, embrace the Dust
Post by: youhn on November 24, 2014, 05:48:15 PM
Some heavy things lurk around above the surface of fractal 3D worlds. This image captures the onset of the big dust storm, which would later convert the shallow oceans of this planet to brown slurries. Lots of minerals and enough radiation from the nearby star though, so evolution will prevail.

Created with Mandelbulber 1.21-1, with quick hack to add the ABS operator to "fast_trig" formula:

Code:
{
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 = fabs(newx) + constant.x;
z.y = newy + constant.y;
z.z = fabs(newz) + constant.z;
r = z.Length();
break;
}
