I suppose that a 1-sided polygon is (like, for example, in OpenGL) a polygon
that is seen only from one side. If the polygon is turned so that the other
side faces the camera, then it's not rendered.
Povray only uses 2-sided polygons (ie. they are rendered now matter how they
are rotated). I don't know of any plans of adding support for 1-sided polygons
to povray (I'm not even sure how easy it is to make in raytracing).
(I think that many people here will answer you with the double_illuminate
thing, but I suppose that that was not what you are asking, but I think it's
that visibility thing. Correct me if I'm wrong.)
