rgl (version 0.100.54)

tkpar3dsave: Modal dialog for saving par3d settings

Description

This function opens a TCL/TK modal dialog to allow particular views of an rgl scene to be saved.

Usage

tkpar3dsave(params = c("userMatrix", "scale", "zoom", "FOV"),
          times = FALSE, dev = rgl.cur(), ...)

Arguments

params

Which parameters to save

times

Should times be saved as well?

dev

Which rgl device to work with

...

Additional parameters to pass to tktoplevel

Value

A list of the requested components. Each one will consist of a list of values that were current when the Record button was clicked. These are suitable to be passed directly to the par3dinterp function.

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

# NOT RUN {
if (interactive()) {

  # 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) ) )
}
# }
