Re: using varying res models at varying distance

I'm creating a forest setting, so I want to use this trick for two things.

One are the models in the forest, trees mainly.  To have an acceptably
distant horizon there will be a lot of models alive at any given time
(give the tree density of a realistic forest), so I want to use lower res
models as distance increases.

Secondly, I want to have fairly detailed terrain, enough that it looks
believable, but an extruded surface that spans the visible horizon will
have millions of vertices (and be drawn with an intolerably enormous
texture to get good looking patterns in the near foreground) if I don't
drop the resolution of both geometry and texture off as the individual
terrain tiles become distant from the camera.

Thanks.
