[Fluxus] Pdata-Question

hi Luis,

yes, pdata-map! loops through all the vertices' pdata and sets the pdata 
according to the function you specify.

you can't see anything, but what happens is that you set all the 
vertices to the same coordinate (vector 1 3 0). that's why the sphere is 
  converted to a point that you cannot see.

hope it helps.

best,
