Details

This opens a TCL/TK modal dialog box with Record and Quit buttons. Each time Record is clicked, a snapshot is taken of current par3d settings. When Quit is clicked, the dialog closes and the values are returned in a list.

If times == TRUE, then the times at which the views are recorded will also be saved, so that the play3d function will play back with the same timing.

Examples

if (interactive() && !in_pkgdown_example()) {

  # Record a series of positions, and then play them back immediately
  # at evenly spaced times, in an oscillating loop
  example(plot3d)
  play3d( par3dinterp( tkpar3dsave() ) )

  # As above, but preserve the click timings

  # play3d( par3dinterp( tkpar3dsave(times=TRUE) ) )
}
