firts option, of witcj I doubt it is what you're looking for; use the 
parametric macro found at http://members.home.nl/seedseven/#param It 
generates parametric objects using mesh', you can makes mesh "solid" by 
adding the "inside_vector" keyword to it, but only when the shape is 
closed. See "6.5.2.3.1  Solid Mesh" in the docs.

Another option, well more of a wild guess from me, could be to use the 
parametric macro to generate vertices and their companion normals. If you 
want to add thickness to your triangle you could go along each normal for 
a certain distance and create a new triangle there. To make a closed shape 
of the two triangles you'd have to add another six triangles. Or you could 
use a prism instead, but that would be slow with many "triangles".
