.IX PEXSetBFReflectionAttributes
.IX "Back-Face Surface" PEXSetBFReflectionAttributes
.LP
This function creates an output primitive attribute which
sets the back-facing surface reflection
.I attributes.
Surface reflection
.I attributes
consist of
the ambient, diffuse and specular coefficients,
the specular concentration and color,
and the transmission coefficient.
