The Mandelbox, but seen from the Inside. This means a voxel is visible, if and only if its coordinate is no element of the Mandelbox set.

In the center there is also a box. Rendered with low iteration.

Looks like the well known Bulb Trees.

Captivating and groundbreaking pictures. What scale did you use, and how many iterations?

I feel like exploring never before seen ocean depths. The grainy black and white feels like low light photography.

I used a changing scale value. The original Data can be found at:
http://github.com/trafassel/Gestaltlupe/blob/master/settings/Public/Examples/Mandelbox/Plants.xml

This data also includes the following formula (ar=-1.2,ai=0.01 ,aj=0.8 are fixed parameters ):

/// <summary>
        /// Initialisierung
        /// </summary>
        public override void Init() {
            base.Init();

additionalPointInfo=new AdditionalPointInfo();
            // Hier kann z.B. pow oder gr aus den Einstellungen gelesen werden.
        }


// Mandelbox
        public override long InSet(double ar, double ai, double aj,  double br, double bi, double bj, double bk, long zkl, bool invers) {

double gr=50000;
double xx, yy, zz;
          long tw;
          int n;
          double x=0,y=0,z=0;
          double r_n = 0;

          xx = x * x; yy = y * y; zz = z * z;
          tw = 0L;
          double r = Math.Sqrt(xx + yy + zz);
  double scale = ar;
additionalPointInfo.red=0;
additionalPointInfo.green=0;
additionalPointInfo.blue=0;

          for (n = 1; n < zkl; n++) {
if(scale<-1)
scale=scale-ai*(scale+1);

//              ; fold box onto itself 
              if (x > 1)
                x = 2.0 - x;
              else if (x < -1)
                x = -2.0 - x;
             
              if (y > 1)
                y = 2.0 - y;
              else if (y < -1)
                y = -2.0 - y;
             
              if (z > 1)
                z = 2.0 - z;
              else if (z < -1)
                z = -2.0 - z;
             
            //  ; fold sphere onto itself
              double fixedRadius = 1;
              double minRadius = 0.00001;
      double length=   r = Math.Pow(x*x + y*y + z*z,aj);
 //  double length=   r = x*x + y*y + z*z;


            if (length > gr) {
//additionalPointInfo.red=x*x/r;
//additionalPointInfo.green=y*y/r;
//additionalPointInfo.blue=z*z/r;
              tw = n; break;
            }

   double mult=1;

    if (length < minRadius) {
      //  mult=Math.Sqrt(fixedRadius)/(minRadius);
    }   else
 if (length < fixedRadius) {
        mult=Math.Sqrt(fixedRadius)/(length);
  }
   mult*=scale;
   x*=mult;
   y*=mult;
   z*=mult;
   x+=br;
   y+=bi;
   z+=bj;
          }


          if (invers) {
            if (tw == 0)
              tw = 1;
            else
              tw = 0;
          }
          return (tw);

        }

I'd be interested to know what it looks like if aj is 0.5 and ai is 0. Does it affect the shape of the turnips? smiley

The Bulb is a hole in the Mandelbox - and in this hole there is a hidden death star.

A inside view of the Mandelbox with aj is 0.5 and ai is 0 (I choose ar=-1.8 ) .


But I cannot find the the turnips.
