Blob Farm


The blob in all its glory:

Twirl with your mouse

This is an ellipsoid derivative that coudl turn into a rather unimaginative but relatively space efficient case.

Octave Code:
  # name of the blob
  project = "blob58";  

   # function at origin must be <0, and >0 far enough away.  w=0 defines the surface
function w = f(x2,y2,z2,c,r)  # three lobed toroid with low profile bumps and flat top
   x = (x2-c(1))/r(1);
   y = (y2-c(2))/r(2);
   z = (z2-c(3))/r(3);

   w=((x).^2+(y).^4+(z).^4)-1; # ellipsoid


  c_outer = [0,0,0];
  r_outer = [180,80,50]; 

 xmin = floor(-200); 
 xmax = floor(200 );

  step = 4;  # grid pitch in mm  start with 4mm to see the shape quickly.  Once you have it just right, change to 2mm for printing
