propertyControl: Controls to use with playwidget()

Controls to use with playwidget()

Description

These are setter functions to produce actions in a Shiny app, or in an animation.

Usage

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)

Arguments

value	The value to use for input (typically input$value in a Shiny app.)
subsets	A list of vectors of object identifiers; the value will choose among them.
fullset	Objects in the subscene which are not in fullset will not be touched.
subscenes	The subscenes to be controlled. If NULL, the root subscene.
accumulate	If TRUE, the subsets will accumulate (by union) as the value increases.
entries, properties, objids	Which properties to set.
tags	Select objects with matching tags. Ignored if objids is specified.
values	Values to set.
param	Parameter values corresponding to the rows of value
interp	Whether to use linear interpolation between param values

Details

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.

Value

These functions return controller data in a list of class "rglControl".
