This is very interesting, but almost all the vertical edges seen in this
example are perpendicular to the x and z axis (assuming y is up). I'd be
more interested in seeing how it handles diagonal and arbritrary
vertical edges. For example, what would it look like if the basis of the
hf were a simple white filled circle on black background? With
antialiasing? Without?
