R packages - Jul 2009 - New package for interactive brushing/cropping/deleting points from RGL : sculpt3d v 0.2

sculpt3d is a GTK+ toolbar that allows for more interactive control of a
dataset inside the RGL plot window.
Controls for simple brushing, highlighting, labeling, and mouseMode changes
are provided by point-and-click rather than through the R terminal
interface.

Package at:
http://cran.r-project.org/web/packages/sculpt3d/index.html

sculpt3d works with a subset of rgl's plot3d arguments, and controls an rgl
device by proxy.  The intent is to allow an individual to quickly
label/unlabel and pare down three dimensional data points.  Once interesting
parts of the original data set have been isolated, a call to
sculpt3d.current() or sculpt3d.selected() will return a logical vector,
indicating which of the original data points are still visible or selected.

It is also possible to set up additional callback functions with
sculpt3d.setCallback(), which can enable brushing/filtering across multiple
views.

There are some warnings/issues with different OS platforms, see the
documentation for details.

Best,
-Justin
