Basically no... Analytic AA is a really hard problem for video games, and I know of no general purpose solutions.

For font and 2D vector rendering it's likely, in fact afaik, some solutions, such as Slug already do.

But for 3d rendering I don't know of any solutions.

For an intuition, consider two triangles that intersect the same pixel.

Consider if say one has 20% coverage and the other 30%, does that pixel have 50% coverage, 30% by one, 20% by one and 10% by another, or any other conceivable mix? It's very difficult to say without selecting specific points and sampling directly.
