par3dinterpControl {rgl} | R Documentation

## Control rgl widget like par3dinterp().

### Description

This control works with `playwidget` to change settings in a WebGL display in the same way as `par3dinterp` does within R.

### Usage

    par3dinterpControl(fn, from, to, steps, subscene = NULL, omitConstant = TRUE, ...)

### Arguments

`fn` | A function returned from `par3dinterp`.
`from, to, steps` | Values where `fn` should be evaluated.
`subscene` | Which subscene's properties should be modified?
`omitConstant` | If `TRUE`, do not set values that are constant across the range.
`...` | Additional parameters which will be passed to `propertyControl`.

### Details

`par3dinterpSetter` sets parameters corresponding to values produced by the result of `par3dinterp`.

### Value

Returns controller data in a list of class "rglControl".

### Examples

    example(plot3d)
    M <- r3dDefaults$userMatrix
    fn <- par3dinterp(times = (0:2)*0.75, userMatrix = list(M,
                                          rotate3d(M, pi/2, 1, 0, 0),
                                          rotate3d(M, pi/2, 0, 1, 0)),
                                          scale = c(0.5, 1, 2))
    control <- par3dinterpControl(fn, 0, 3, steps = 15)
    control
    if (interactive())
      rglwidget(width = 500, height = 250) %>%
      playwidget(control,
           step = 0.01, loop = TRUE, rate = 0.5)
