At the moment these triangles must be on a geometrical surface that 
bounds the volume ("Embedded Point" or "Embedded Curve" are not yet 
supported in 3D). You'll thus need to define your volume accordingly 
(probably by splitting it in 2 parts, their common boundary being the 
"constraint surface").
