| Description | As outlined by various comparative studies, there's an ongoing question of suitability of certain (cartographic) visualizations & visualization elements for tasks at hand - be it specialized cases, unique visualization interfaces, etc. However it may be, in the end, a recipient always processes such "suitability" through human visual perception and cognition. In this paper, our approach was to take a step back from the comparative research, and to offer a theoretical overview of visual cognition and graphics pipelines instead. I.e., we put together a working model for each, followed by our comparison of the two. Specifically: we revisited notable cognitive psychology theories on processing visual stimuli, and from these, we extracted a hierarchical working model; as for computer graphics, we reviewed existing 3D graphics pipelines, along with contemporary visualization engine implementations. The purpose of this theoretical detour was to provide grounding for research that is to follow. Not only do our findings unveil potential experimental cases, they also prove an insight on what is feasible in the context of today's visualization engines and hardware. |
