Well now, you seem to be doing exactly what I started doing when I started
on 3D stuff, going over the top and trying to do an all-singing all-dancing
amazing 3d thingy, then writing something more simple and not going insane
:-).

To get to the point, I reckon the shift paramater is to make the accuracy of
the clipping up to the maximum by shifting to the right that many times
(right shift is equivelant to dividing a number by two) so the call should
look like this :

GsSortObject4( &object, &WorldOrderingTable[outputBufferIndex],
14-OT_LENGTH, etc. etc. la de dah

or somthing.

On a different note, try looking at the 3D flying tutorials ( if you haven't
already :) ), as they work 'quite' well, and at least the don't crash
spectacularly like most of my code !!

anyway, hope that discombobulated answer was not to incomprehensible ;~/.
