# fig12.10.rib - RIB to create Figure 12.10 of:
#
# _Advanced RenderMan: Creating CGI for Motion Picture_, 
# by Anthony A. Apodaca and Larry Gritz, Morgan Kaufmann, 1999.
#
# This file demostrates the oak shader.
# The lights in this file assume ray tracing -- either BMRT or 
# frankenrender will work, but plain PRMan will not have shadows unless
# you make your own shadow map and modify the file to use it.  Sorry.
