I think points 3 and 4 are transposed in my definition. The sort of points by your definition is not the sorting I envisioned as I wrote my definition of surfaces.
+/&.|: 1 = points 0 1 1 2 1 2 2 3 (= /:~) +/&.|: 1 = points NB. should be 8#1 1 1 1 0 0 1 1 1 Alas, I don't have more time at the moment to pursue corrected definitions such that points and surfaces would match up. -- T On Thu, Apr 1, 2010 at 4:55 PM, Raul Miller <[email protected]> wrote: > On Thu, Apr 1, 2010 at 3:56 PM, Tracy Harms <[email protected]> wrote: > > Perhaps something like this? > > > > ( , 7-]) |: 0, 1 2 4 +"_1 _ i.3 > > 0 1 2 4 > ... > > That does not look right, to me, for the set of points I had defined. > Can you define a set of points where this works? > > For example: > 0 1 2 4 { _1+2*#:i.8 > _1 _1 _1 > _1 _1 1 > _1 1 _1 > 1 _1 _1 > > That looks like the edges at one > corner of the cube, but does not > look like the surface of a cube. > > As an aside, I did not transcribe my own code properly. > I should have used 1 A."1 > > 1 A."1 I.
