initial hull is narrow

[Bernd Dau]

Hi list!
does anybody knows what that means?
---
qhull precision warning: 
The initial hull is narrow (the cosine of the minimum angle is
-0.999971747).
A coplanar point may lead to a wide facet.  Options 'Qs' (search for
best
initial hull), 'QbB' (scale to unit box), or 'Qbb' (scale last
coordinate)
may remove this warning.  Use 'Pp' to ignore this warning.
See 'Limitations' in qh-impre.htm.

The  qh-impre.htm isn't in the demo is it?

By the way: the guys specially Ryan have done very well.
The Game runs very well
