# fig8.6.rib - RIB to create Figure 8.6 of:
#
# _Advanced RenderMan: Creating CGI for Motion Picture_, 
# by Anthony A. Apodaca and Larry Gritz, Morgan Kaufmann, 1999.
#
# This file demostrates what can go wrong if you do not supply
# the correct displacementbound.  Note the missing slivers.
# NOTE: due to the different ways that the renderers process data,
# this artifact will be very clear with PRMan, and may not be apparent
# with BMRT (but it can still happen, so don't forget displacementbound!).
#
# This file requires lumpy shader in ../shaders.
