Re[2]: [Algorithms] Colliding against polygon soup

[Cruise <Cr...@wy...>]

This is a pretty good method if you don't need the exact location,
just area-based. The one problem with the way Half-Life implemented it
is it doesn't allow bones to be removed from the model in game...if
you want a charcter to lose an arm, even if you don't draw it anymore,
the bone (and therefore hit-box) still remains.

This presumably wouldn't be a problem when testing at the polygon
level, as the polygons for the arm no longer exist (or at least aren't
visible).
