Hi Amir,

The three plane intersection is an issue that I ran into also, as you 
will see in the following journal paper where I suggest a workaround if 
you need to use cartesian doubles for some reason (such as for speed).

http://dx.doi.org/10.1016/j.comgeo.2006.11.003

I can send you the paper or the code fragment off the list, if you are 
interested.  Essentially it is solving for the intersection point of all 
three planes directly (using Cramer's rule) rather than doing 
intersections two planes at a time.

Regards,
Deepak.
