Shortest conversion from vector to vector of pointer

Is there any shortcut to convert from std::vector<T> to std::vector<T*> or std::vector<T&>?

Essentially I want to replace:

std::vector<T> source;
std::vector<T*> target;
for(auto it = source.begin(); it != source.end(); it++)
{
  target.push_back(&(*it));
}

with a single line.

To provide some context: I have one set of functions which do their computation on a std::vector<Polygon> and some which require std::vector<Polygon*>. So I need to convert back and forth a couple of times, because the interface of these functions is not supposed to change.
