##RenderMan RIB-Structure 1.0
version 3.03

###########################################################################
#
# This RIB file demonstrates some more complex procedural textures.
# Two spheres show the use of "stucco" and "dented" displacement shaders.
# The floor shows the gmarbtile_polish shader, which is polised green
# marble tiles.  Note that the reflection is accomplished by the shader
# actually calling the trace() function, rather than reflection mapping.
