Comment(by robe):

 I made a change to the doco at r13183

 Check it out and see if it makes sense
 http://postgis.net/docs/manual-dev/ST_3DIntersects.html

 One thing I am not sure about is how SFCGAL treats closed surfaces.  As I
 recall I think it treats it as a solid and so ST_3DIntersects for closed
 polyhedral surfaces may return a different answer than what the built-in
 ST_3DIntersects returns.  Also the documentation was a bit out-dated in
 that lwgeom only sT_3DIntersects does support polygons and polyhedral
 surfaces (I think this may have been a limitation in early 2.0, but got
 changed at release time thought it hasn't been very stress tested).  I'll
 have to verify that before I backport.
