I found your page very interesting, complete and I really appreciated the 
torough comparison. Definitely well done.

From a cg purist programmer point of view (and as you point out in the 
introduction) I would not define your structure as a BSP-Tree but as a Kd-
Tree because with BSP-Tree I mean a structure that can divide the space 
along arbitrary planes (not only axis aligned) and that oblige to split 
geometry that crosses those planes boundaries.

I hope your patch will be considered for inclusion in the MegaPOV 
experimental version and, why not, in a future POV version.

Could you please comment on why the shells7.pov scene is so badly managed 
by the Kd-Tree structure?
