# plycull.tcl -- David Koller (dk@cs.stanford.edu), 8/16/98
#
# This program is a wrapper for the "plycullmaxx" program which
# culls a .ply file to an axis-aligned bounding box.  This program
# takes 3 arguments: a .ply file, which is used to define the
# bounding box, and an input and output .ply filenames:
#
#      plycull file.bbox.ply infile.ply outfile.ply
#
# This program was written with the intent of working with data
# files output from a "vripsplit" process.
