A system and method for providing a dynamic user interface for a dense three-dimensional scene with a navigation assistance panel is presented. Clusters of semantically scored documents are placed in a three-dimensional scene and are arranged as a cluster spine. Each cluster spine is projected into a two-dimensional display. Controls operating on the cluster spines in the display are presented in a user interface. Compasses framing the cluster spines within the display are provided. A label to identify one concept in one or more of the cluster spines appearing within at least one of the compasses is generated. A plurality of slots in the display positioned circumferentially around the compasses are defined. Each label is assigned to the slot outside of the compass for the cluster spine having a closest angularity to the slot. A perspective-altered rendition of the two-dimensional display is provided by a navigation assistant panel.
