grid1 150 grid2 150
pu setxy -90 -180 pd label (se "PURE "GLASS "to "KW "MELVIN)

to grid1 :a
for [theta 0 180 15][for [fi 0 180 5][col sppos :a* sin(:theta*4) :fi :theta

to grid2 :a
for [fi 0 180 5][for [theta 0 180 15][col sppos :a* sin(:theta*4) :fi :theta

to mysetxyz :a :b :c
;isometric transform
setxy (:a- :c)*cos 30 :b- (:a+ :c)*sin 30

to sppos :r :fi :theta
;spherical co-ordinates
