Hello all!
I recently plugged in old TNT2 (nv05) card and started to playing with it.
This hardware can do quads and triangles, but not lines or points .... So, i
need to emulate them.
utah-glx has some code exactly for this generation of hardware:
http://utah-glx.cvs.sourceforge.net/viewvc/utah-glx/glx-xf3/servGL/hwglx/nv/riva_prim.c?revision=1.11&view=markup
I tried to cook up something like this for current nouveau driver, but nearly
failed.
Lack of hardware PolygonOffset support lead me into
src/mesa/tnl_dd/t_dd_tritmp.h , used in many drivers. Currently, it can only
DE-compose triangles, but can (or better - should) it be abjusted for
creating additional vertex info (2->4, 1->4) ?
Should one still use this file in modern world? On non-hw-tcl capable hw .....
