   Hey folks,

   I'm trying to use the pfuSmoke routines and seem to be having trouble
   getting the eye argument for the pfuDrawSmokes call...

      void pfuDrawSmokes (pfVec3 eye);

   I've created a custom draw routine as follows...

void myDrawFunc (pfChannel *chan, void* data)
{
   static pfVec3 eyept;

   chan->clear ();
   chan->getEye (eyept);

   pfuDrawSmokes (eyept);

   pfDraw();
}

   I get a SIGBUS on the chan->getEye call? here is the trace...

Process 13924 (dbase) stopped on signal SIGBUS: Bus error (default) at
[pfFrustum::getEye(pfVec3&) const:3344 ,0x3fe45428]
         Source (of ../../../lib/libpr/pfGeoMath.C) not available for Process

   What am I doing wrong?

   Thanks in advance,
