This object cache model stores physical objects in a spatial grid. Each cell maintains a list of intersecting physical objects. The grid is aligned with the coordinate axes and it has a configurable cell size in all dimensions. The cell size parameters take precedence over the cell count parameters.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.
