Hi,

I'm using trace() to calculate positions of objects in a landscape 
(heightfield ).
Now i'd like to use the normal of the object (returned into the fourth 
parameter of the trace function) to rotate the object before placing it 
onto the landscape.

How can i convert a normal-vector into a rotation-vector?
Sounds easy but i havn't any clue how to do it.
Maybe someone can help ?

Bye
