This is really a C++ question rather than a Boost one, if I have 
understood it correctly.

I usually use an unparameterised constructor for this, and, indeed, 
there is one in the code I am working on right now:

Vector::Vector(void) : x(0.0), y(0.0), z(0,0)
{
    //any other stuff here
}

Does this do what you want?
