:An octtree leaf (OTLF) stores its size and position and the gunk quads that intersect it. The first field contains an index/count pair that is used to access the first [[OBD:IDXA|IDXA]] field that is stored in the [[OBD:AKOT|AKOT]] that owns this leaf. This [[OBD:IDXA|IDXA]] contains the gunk quad numbers that intersect the leaf. | :An octtree leaf (OTLF) stores its size and position and the gunk quads that intersect it.

This [[OBD:IDXA|IDXA]] contains the gunk quad numbers that intersect the leaf. In theory there can be at most 4096 gunk quads that intersect a leaf but in practice this number is much lower (max is 462). In addition the treshold limit used to build the octree seems to be 19 gunk quads per leaf. | ||
