I guess you're right that the omissions are deliberate. Experimenting with
other moduli, I see that many choices give long, spindly results. However,
17 seems to work OK as shown in the following modification of your code:
primenebulaP8_17=: 3 : 0
NB. scan left +/ on movement steps
d=. ({.,#)/.~+/\ (_1 _1,0 _1,1 _1,_1 0,1 0,_1 1,0 1,:1 1){~8|17|p: i.y
NB. normalize coordinates to upper right quadrant and calculate size
'gx gy '=. >: >./ XY=.(2{."1 d) -"1 {.~&2 <./ d
smoutput (": gx),' x ', ": gy NB. show picture size
viewmat (2{"1 d) (<"1 XY) } 0$~ gx, gy
)
I'm attempting to avoid the arbitrary nature of the original algorithm by
specifying the eight likely directions in the plane, i.e. (starting at
"X"):
012
3X4
567
