Blob Farm


The blob in all its glory:

Twirl with your mouse

A nice simple ellipsoid.

Octave Code:
  # name of the blob
  project = "blob68";  
   # function at origin must be <0, and >0 far enough away.  w=0 defines the surface
  function w = f(x2,y2,z2,c,r) 
   x = (x2-c(1))/r(1);
   y = (y2-c(2))/r(2);
   z = (z2-c(3))/r(3);

    w = x.^2+y.^2+z.^2-1.0;  # <<<<<<<<<<<  THE BLOB FUNCTION


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

  # use the default prewarp function
  # use default grid extents (xmin, xmax, etc)

  c_outer = [0,0,0];
  r_outer = [20,40,15]; # this is why it will not just be a sphere
