#!F-adobe-times-bold-r-normal--18* point #!EF #!EF #!I50 #!N is the starting point from
which the grid is constructed. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* structure
#!EF #!EF #!I50 #!N specifies the type of grid geometry and
must be one of the following: "brick " (the default), "crosshair,"
"ellipse," "line," "point," or "rectangle." #!N #!N For a structure specified
as "point," it is neither necessary nor useful to specify #!F-adobe-times-bold-r-normal--18*
shape #!EF or #!F-adobe-times-bold-r-normal--18* density #!EF . For the other valid
structures, the output object extends symmetrically from #!F-adobe-times-bold-r-normal--18* point #!EF .
#!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* shape #!EF #!EF #!I50 #!N is
a list of vectors that characterize the grid structure, specifying its
size and orientation: A line requires one vector; rectangles and ellipses,
two vectors; and bricks and crosshairs, three vectors. For "brick," the
default #!F-adobe-times-bold-r-normal--18* shape #!EF specification is {[1 0 0] [0 1
0] [0 0 1]}; for other structures, the default specification is
the appropriate corresponding vector list. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* density
#!EF #!EF #!I50 #!N determines the number of points in the
output. For crosshairs and bricks, the specification is a list of
length 3; for rectangles, a list of length 2; and for
the other structures, a single integer. In each case, #!F-adobe-times-bold-r-normal--18* density
#!EF is the number of points along the edge in question.
Bricks and rectangles are filled. #!I0 #!N #!N Note: Specifying #!F-adobe-times-bold-r-normal--18*
point #!EF and #!F-adobe-times-bold-r-normal--18* shape #!EF as 2-dimensional vectors can produce
a 2-dimensional output #!F-adobe-times-bold-r-normal--18* grid #!EF for the structures "ellipse," "line,"
"point," and "rectangle." #!N #!N Components #!N #!N Creates "positions" and
