Hi again!
BTW, this is the out of the profiler. If I read correctly, there are
~33.000.000 floats? What for?
Line 4/5 have exactly the size of my index arrays. Why are there 2 of them?
Ok, I know there have to be target structures during T&L. But so much?
May it be that the structure is jsut TOO big an Java3D breaks them up
internally again to unindexed structures? Would it help breaking them up
myself? Dealing them unindexed myself?
