Hello,

I understand that to get an object's matrix back to have perfectly
perpendictular axis and proper scale (after it has gradually been corrupted
by many rotations) you can some how use a cross product or a dot product
method, but I don't know any more than that.  And I can't immediately
work-out how it's done.  Can anyone explain it further (which elements of
the matrix you do what to etc), or perhaps give me a code snippet?

Cheers,
Jon Prestidge.
