I would like people to discuss about efficient spatial organization
of a database.

Let's say that I have a database organized on disk as beeing a group of tiles
and in each tile we can find these elements :

     1) A list of ground polygons and for each of these polygons,
        a list of coplanar polygons.
     2) A list of 3D polygons not beeing considered ground
        (not to be used for HAT intersection).
     3) A list of model's references (some SCS and some DCS).

How should the Performer's scene be organized to get the best results for
drawing ? I just want to investigate what people think about this issue.

Thanks in advance !

Rejean.
