THE ABSTRACTION ALGORITHM needs WebGL2.

THE ABSTRACTION ALGORITHM

David’s formulation of the corpus’s own loop, made to run: r0 is the origin and the sink; the five worlds seed vectors; I-13 is the transfer function; the outputs are a voxel field; it folds back to r0. Every voxel below is a real I-13 map step.

r0{ [ point . vector .. voxel ] }
  ~> { vector(in) , (i13) , vector(out) }
  ~> | voxel field , ( / \ | \ / )
  ~> | voxel field vector ( multiverse )
  ~> r0 .

reading it: the dimensional ascent point→vector→voxel enters I-13; a vector goes in, a vector comes out; the outputs fill a voxel field; the crossing ( / \ | \ / ) is the diamond pivot where the five worlds meet; the field spans the multiverse and folds home to r0.

{ vector(in) · (i13) · vector(out) }

the transfer function is a real I-13 program — a rotation+contraction, its cos/sin from the stdlib (bounded Taylor):

def cos(x){ … }  def sin(x){ … }
xout <- s * (x*ct - y*st)
yout <- s * (x*st + y*ct)

vector(3,1) → i13 → (1.98105637530, 2.13059044349) ✓ the JS drawing this field mirrors it to all 16 digits — the voxels ARE the I-13 output.
