"Don't forget J3D un-indexes indexed geometry structures before passing
them to the card"
So is it better and faster to use directly non indexed geometry arrays ? The cost of memory in non indexed geometry is less than using indexed geometry ?

Are you constructing your own, or using the one in the j3d.org
repository. The one I have there generates from 512 square images and
renders them quite fine with no memory problems.

Don't forget J3D un-indexes indexed geometry structures before passing
them to the card. Maybe try using J3d 1.3 and the USE_COORD_INDEX_ONLY
so that it only needs one copy of the index array.
