# Line 60 | Line 66 | in any number of
66   and
67   .I \-f
68   options.
69 + The variable and function definitions in each
70 + .I \-f source
71 + file are read and compiled from the RADIANCE library where it is found.
72   The
73   .I \-s
74   option adds smoothing (surface normal interpolation) to the surface.
75   The
76 + .I \-i
77 + option reverses surface normal directions from the standard
78 + clockwise-from-front orientation.
79 + The
80   .I \-o
81   option produces a Wavefront .OBJ file rather than a RADIANCE
82   scene description.

129   .SH BUGS
130   The smoothing operation requires that functions be defined
131   beyond the [0,1] boundaries of s and t.
