You probably don't want to hitbeam the entire sector. If you do, it will
intersect every mesh in the scene. So, if you hitbeam, find the terrain,
place some sort of player mesh at that location, then the next hitbeam will
probably intersect the player instead of the terrain.
I believe TraceBeam will work for you. This is like HitBeam, except it uses
the CD system, so it will only interact with the world and not meshes moving
around. So, basically you start with your position (<-13,0,20>), use a
start that's sufficiently high so that you know it's higher than the surface
of your terrain (maybe <-13,100,20> will do), and use an end that's
sufficiently low so that it is guaranteed to intersect the terrain (maybe
<-13,-100,20>) and then grab the intersection (which will be <-13,x,20>
where x is the height of the terrain at that point).
Note: I'm not sure if TraceBeam will work with terrain and I have absolutely
no idea whether this is the best solution or not to your problem, but I
think it will work.

Thanks,
but I still don't see how to do it...
Let's say I have a csVector3(-15,0,20) and an iSector... How can I
retrieve
the elevation vector for this position ? Hitbeam take start and end (of
what ?) and return a csVectorHitBeamResult ? How is this supposed to be
use ?
