I still haven't got what the hell this has to do with dolphin at all. As all of the wii/gs games renders by polygons, we also have to do it in this way. Funny fact, they could also implement some kind of raytracer, at least the native gpu is flexible enough to do so.
We don't emulate a 3d engine, we emulate a gpu, so we are only able to execute the original software, which just use polygons.
