Quake3World

hi, does quake3 make use of lod for objects?

i downloaded the arena 1.27 src release and built the code successfully but rummaging through the code, i couldn't seem to find anything on lod...

there is a prgramming discussion forum in case you don't get any replies.
i have no idea what lod is

googled lod=level of detail

i'm not 100% sure, but doesnt q3a only have lod of 1 or 0 ?

ok, just checked my cfg and only found these

seta r_lodbias "0"
seta r_lodCurveError "250"

someone explain for the lazy ones please

It uses it for certain things, I've noticed it for icons (I use 2d icons for pickups). Not exactly sure I think it's because I use GL_LINEAR_MIPMAP_NEAREST. A short distance away (I would say less than 10 feet) the icons become a bit fuzzy. Oh and it uses it for textures too.

Negative r_lodbias gives you a sharper image, and positive will blurr certain things a distance away.

iirc curves, items(ammo health), and mapmodels have lod.
don't kill me over the latter two please.....

r_lodCurveError Controls distance at which curves are dropped, range 0 to 10000 where 0 is always drop curves and 10000 is never drop curves.


r_lodBias Controls model or weapon etc mipmap/geometry detail, range -2 to +2 where +2 is lowest geometry and -2 is highest.

i see the r_lodbias set at -2 for best visuals and r_lodcurveerror at 10000 also for best visuals

i'll change that tomorrow and have a look..
