RE: [Algorithms] Single mesh vs segments

[Tom F. <to...@mu...>]

There's pros and cons. Skinned models generally use fewer vertices, however
they can be fully accellerated by the D3D pipeline in a fairly trivial way.
Then again, if you do that you need to break up your stream of vertices with
matrix changes fairly often, which is often (usually?) a lose.

Skinned characters tend to look smoother and less like they're insects
wearing human skin in a grisly Hannibal-Lecter way. Depending on how you do
them, they can be accellerated by the D3D pipeline to varying degrees, which
is nice. But the no.1 cool thing about them in my book is that they VIPM
really really well. You can also get away with fewer tris and vertices than
on a segmented model for equivalent preceived detail. You may have noticed
that I'm a big fan of scalability.

So it's swings and roundabouts - on the one hand segmented is simple. But
it's a bit ugly, not as flexible and uses more tris and vertices.
