Basic Meanings of Spatial Computation and Evaluation in 3D Space

Spatial relations play an important role in the re-search area of connecting visual and verbal space. In the last decade several approaches to seman-tics and computation of spatial relations in 2D space have been developed. Presented here is a new approach to the computation and evalu-ation of basic spatial relations ’ meanings in 3D space. We propose the use of various kinds of ap-proximations when defining the basic semantics. The vagueness of the applicability of a spatial relation is accounted for by a flexible evaluation component which enables a cognitively plausible continuous gradation. For validating the evolved methods we have integrated them into a work-bench. This workbench allows us to investigate the structure of a spatial relation’s applicability region through various visualization methods
