Largely [[MREA (Metroid Prime)#World Geometry|the same as Prime 1]]. There are two new sections to watch out for on each world model (described on the [[Geometry (Metroid Prime)]] page). There's two sections that are now grouped under the same section number as world geometry.

The first is the [[MREA (Metroid Prime)#Area Octree|area octree]] section, which is back from Prime 1 but no longer has its own section number.
==== Area Octree ====
 
The [[MREA (Metroid Prime)#Area Octree|area octree]] section is back from Prime 1, but no longer has its own section number - it's now grouped under the same section number as world geometry.
 
==== Surface Group Bounding Boxes ====


The second section is an array of a structure that provides the bounding box for every surface group. The first entry in the array has the combined bounding box for all of the world geometry in the entire area, then each surface group is listed in order.
This is a new section introduced in Metroid Prime 2, which is grouped under the world geometry section number and appears after the area octree. It contains an array of a structure that provides the bounding box for every surface group. The first entry in the array has the combined bounding box for all of the world geometry in the entire area, then each surface group is listed in order.
