subramn@cs.utexas.edu (K. R. Subramanian) (05/15/89)

	A long time ago there was a discussion on the Liang-Barsky clipping
algorithm and some bugs in the original paper:

	"A new concept and method for line Clipping", Y.D.Liang, A.Barsky,
	 ACM Transactions on Graphics, Jan. '84.

Were these mistakes fixed in a later publication. Any info on this is
appreciated.

Please e-mail.
