These are setter functions to produce actions in a Shiny app, or in an animation.
subsetControl(value = 1, subsets, subscenes = NULL,
fullset = Reduce(union, subsets),
accumulate = FALSE)
propertyControl(value = 0, entries, properties,
objids = tagged3d(tags), tags, values = NULL,
param = seq_len(NROW(values)) - 1, interp = TRUE)These functions return controller data in a list of class
"rglControl".
The value to use for input (typically input$value
in a Shiny app.)
A list of vectors of object identifiers; the value will choose among them.
Objects in the subscene which are not in fullset
will not be touched.
The subscenes to be controlled. If NULL, the
root subscene.
If TRUE, the subsets will accumulate (by union)
as the value increases.
Which properties to set.
Select objects with matching tags. Ignored
if objids is specified.
Values to set.
Parameter values corresponding to the rows of value
Whether to use linear interpolation between param
values

subsetControl produces data for playwidget to
display subsets of the object in one or more subscenes. This code will not
touch objects in the
subscenes if they
are not in fullset. fullset defaults to the union of
all the object ids mentioned in subsets, so by default if an id is
not mentioned in one of the subsets, it will not be controlled by the slider. If value is specified in R code, it will be a 1-based
index into the subsets list; when specified internally
in Javascript, 0-based indexing into the corresponding array
will be used.
propertyControl sets individual properties. Here the row
of values is determined by the position of value
in param.

control, and playwidget for a way to use these
