rglIds {rgl} | R Documentation |
All objects in an rgl scene have a
numerical id. These ids are normally stored
in vectors of class c("rglIds", "numeric")
, which
will also have class "rglHighlevel"
or "rglLowlevel"
depending on
whether a high level function like
plot3d
or persp3d
, or a low level function created the objects.
lowlevel(ids = integer()) highlevel(ids = integer()) ## S3 method for class 'rglId' print(x, rglwidget = getOption("rgl.printRglwidget", FALSE), ...)

These functions and classes are intended to allow
rgl scenes to be automatically
displayed in R Markdown documents. However,
this is not fully in place yet, so
explicit rglwidget()
calls are
still recommended.
Note that all objects in the current
scene will be printed by default, not just
the ids in x
. (The reason for this
is that lights are also objects; printing
objects without lights would rarely make
sense.)
Objects of class c("rglHighlevel", "rglId",
"numeric")
or c("rglLowlevel", "rglId",
"numeric")
.
