Some of your pics are entirely done on the shaper, one was entirely carved, some were a combination of the shaper followed by hand carving. Shaper is a giant router table but the bits are up to 5" diameter. The curved-top doors and rounded panel moldings can be done with just a router.

Some can be purchased from Outwater or Van Dykes.

Most of those frames are likely cut to shape or fashioned from molded resin or MDF. Notice that almost all of the pieces have opaque finishes and not clear finish. My guess is whatever is underneath the finish is ugly material.

The piece in the second picture looks like an exception. The curves are fairly gentle and are probably cut out of a larger piece of material.

It's quite possible to bend large pieces of wood to severe curves but that's a time-consuming and expensive process for most people. Steam-bending was popular before the Second World War but you'll almost never find that technique used in modern factories.
