tkpar3dsave: Modal dialog for saving par3d settings
In rgl: 3D Visualization Using OpenGL

Description Usage Arguments Details Value Author(s) See Also Examples

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

1 2	tkpar3dsave(params = c("userMatrix", "scale", "zoom", "FOV"), times = FALSE, dev = cur3d(), ...)

`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`

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.

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.

  # Record a series of positions, and then play them back immediately

  # As above, but preserve the click timings
