Subject:[3DWorld] Inverse matrix?

Hi All,

I know it`s not practicle to calculate the inverse of a matrix but I need the
inverse matrix every loop. Is there a way of keeping a running copy of the
inverse? ie Every time I change the first matrix I change the inverse so that
it remains the inverse.

I`ve run up against this problem before and have always used a hack around to
solve it but this time I cant see a solution so any help would be apreciated.
