The invariant applies to a line bundle over a variety: that is, a continuously glued collection of vector spaces over a shape (itself over an algebraically closed field). There is a beautiful connection in the simplest cases with a computation over the Okounkov body of the line bundle in question, the latter being a simplex we can associate to the line bundle which encodes data about it.
