Abstract: We present a study of visual representations for large-scale scientific data. While non-photorealistic rendering techniques encapsulate significant potential for both research and deployment, photorealistic visualizations remain king with regard to accessibility and thereby acceptability. Therefore in this work we endeavor to understand this phenomenon via the creation of the analogous visualizations in a setting that is readily comparable. Specifically, we employ identical non-color parameters for two visualizations of scientific data, CM1 simulation output data. In the first data elements are colored according to a natural diagrammatic scale and in the other physically-based techniques are deployed. The visualizations are then presented to a domain scientist to illicit feedback toward classifying the effectiveness of the different design types.
