Hi, (referring back to my posts last week in
scea.yaroze.programming.3d_graphics) has no one got any ideas how I can
get my single skin mesh models to work using GsLib? I'm looking into MIM
(or is it MIME?) like in the Dino demo, but since there's only one
function documented and nothing else that I can find, I'm not too
hopeful that it's the solution I'm after either.

To briefly restate my questions -

1. I want to have single mesh character models deformed by bones, and
hope to leverage the PlayStation's hardware to do so in order that I
don't have to transform the vertices associated with bones without the
aid of the hardware multiplier.

2. When creating poly's on the fly, is it important that normals be of
unit length, because if not I'll save a lot time by skipping the
normalization step.

3. If I have to normalize the normals, can anyone think of a way to
extend my wacky theta=atan2(x,y), normx = sin(theta), normy = cos(theta)
idea to 3D? Or is there a really fast way to normalize that avoids
floating point and I haven't been able to think of yet?
