TAB #!EF #!N #!N Functional Details #!N #!N This module creates
a glyph, or representation (e.g., an arrow), for each data value
in a data field #!F-adobe-times-bold-r-normal--18* data #!EF . For data dependent
on positions, a glyph is placed at the corresponding position. For
data dependent on connections, a glyph is placed at the center
of the corresponding connection element. If there is no "data" component,
a glyph is placed at each position. #!N #!N The "base"
size (i.e. size of a glyph for the average data value)
is based on AutoGlyph's estimate of an appropriate glyph size, as
modified by #!F-adobe-times-bold-r-normal--18* scale #!EF . #!N #!N For "text" glyphs,
a "data" component is required. #!N #!N AutoGlyph differs from the
Glyph module in the interpretation of the #!F-adobe-times-bold-r-normal--18* scale #!EF parameter.
For AutoGlyph, you specify the size of the glyphs relative to
the default-size glyph chosen by AutoGlyph. In contrast, when using Glyph,
you may specify a scaling factor that is multiplied by the
data value to obtain the size of the glyph in world
units. #!N #!I0 #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* data #!EF
#!EF #!I50 #!N is the data field for which glyphs are
to be created. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* type #!EF #!EF
#!I50 #!N specifies the kind of glyph to be used. #!N
#!N By default, scalar fields are represented by filled circles or
spheres, vector fields by arrows, tensor fields by groups of arrows,
and string data by text. For 2-dimensional scalar fields, the glyphs
are circles, and for 2-dimensional vector fields, the arrows are flat.
For 3-dimensional fields, spheres or rounded arrows (rockets) are used. #!N
#!N The #!F-adobe-times-bold-r-normal--18* type #!EF parameter will override a default glyph.
If #!F-adobe-times-bold-r-normal--18* type #!EF is a string, it must specify one
of the following: "arrow," "arrow2D," "circle," "colored text," "cube," "diamond," "needle,"
"needle2D," "rocket," "rocket2D," "sphere," "speedy," "spiffy," "square," "standard," or "text." The
value "standard" specifies the default glyph type and is a medium-quality
glyph appropriate to the data; "spiffy," a higher-quality glyph; and "speedy,"
a lower-quality, but more quickly rendered glyph. Lower quality glyphs also
consume less memory. #!N #!N You may alternatively specify #!F-adobe-times-bold-r-normal--18* type
#!EF as a scalar value between 0 and 1, where: #!N
#!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N o 0 is the
same as "speedy" #!N #!I30 #!N o 1 is the same
as "spiffy" #!N #!I30 #!N o 0.5 is the same as
"standard" #!N #!I0 #!N #!EF #!N There are approximately 5 different
quality glyphs for each glyph type. The one closest to the
value specified is used. #!N #!N Specifying "text" or "colored text"
for #!F-adobe-times-bold-r-normal--18* type #!EF puts a text representation of the data
value at each point. For text glyphs, the text is by
default 15 pixels high, and the #!F-adobe-times-bold-r-normal--18* shape #!EF , #!F-adobe-times-bold-r-normal--18*
ratio #!EF , #!F-adobe-times-bold-r-normal--18* min #!EF , and #!F-adobe-times-bold-r-normal--18* max #!EF
parameters have no effect. The #!F-adobe-times-bold-r-normal--18* scale #!EF parameter can be
used to increase or decrease the size of the text glyphs.
For example, specifying #!F-adobe-times-bold-r-normal--18* scale #!EF = 2 makes the text
30 pixels high. The difference between "text" and "colored text" is
that text is always white when "text" is specified, but will
be the color of the input if "colored text" is specified.
Note that after the AutoGlyph module, Color can be used to
color text glyphs to a different color if desired. The font
for the text glyphs can be specified by appending "font =
#!F-adobe-times-medium-i-normal--18* fontname #!EF " to "text" or "colored text," where #!F-adobe-times-medium-i-normal--18*
fontname #!EF is any of the defined fonts supplied with Data
