That's why I was trying to understand better. Your last two answers 
clarify your question better.

Globally, I would support Laurent's answer. Just triangulate the whole 
space and mark tetrahedra that are interior to your shape.

But if I understand well your other e-mail, you already have the 
tetrahedra in the interior as input. And you would need to fill the 
polyhedral holes, which is known to be sometimes impossible...
