I had a similar problem (and its still a problem nearly 3yrs later - I never
had time to dig deeper into the PLIB code) - but in my case I was loading a
sphere from AC3D (a 3D modelling tool) of radius 10 and centred at 0,0,0 -
but when I check its bounding sphere ... getBSphere() I got bounding sphere
radius return 17.9544 ???  And the centre of -1.27190,-0.726630,0.303701 ???

Sorry I don't yet have a solution.  :(
