Called for the side effect of displaying the sprites.
The shape ID of the displayed object is returned.
Arguments
x, y, z
coordinates. Any reasonable way of defining the
coordinates is acceptable. See the function xyz.coords
for details.
text
A character vector or expression. See
plotmath for how expressions are
interpreted.
cex
Character size expansion.
adj
one value specifying the horizontal adjustment, or two,
specifying horizontal and vertical adjustment respectively, or three, for depth as well.
pos, offset
alternate way to specify adj; see text3d
fixedSize
Should the resulting sprite behave like the default
ones, and resize with the scene, or like text, and
stay at a fixed size?
startsize, initCex
These parameters are unlikely to be needed by users.
startsize is an over-estimate of the size (in pixels) of the
largest expression. Increase this if large expressions
are cut off. initCex is the size of text used
to form the bitmap. Increase this if letters look too blurry
at the desired size.
margin, floating, tag
material3d properties.

Additional arguments to pass to
