A complete qualitative scene description should be such that it captures the essential details of a configuration so that a topologically correct depiction can be recreated. This paper models a spatial scene through sequences of point partitions, that is, how embedding space and objects are distributed around the intersections of the boundaries of regions. A set 23 base patterns are identified, which suffice to capture complex scenes, including configurations with holes. To demonstrate the diagrammatic depiction of a spatial scene from point partition patterns, such a scene is recreated using the developed model. The paper also provides a means of transitioning between these more complex relations and the coarse relations of the 9-intersection.
