| Abstract |
3D modeling offers significant potential for visualizing simulation data and design processes, thereby enhancing their interpretability and communicability. This study aims to examine how varying levels of detail (LOD) in virtual urban simulations -developed using computer graphics tools- influence cognitive responses to both virtual and real urban environments. To assess these cognitive responses, data were collected and analyzed using questionnaires and eye-tracking techniques, capturing both psychological and physiological observational responses. The results indicate that as LOD increases, the perceptual discrepancy between virtual simulations and real environments diminishes. However, a decline in similarity scores was observed for certain items at LOD 4, which is attributed to potential limitations related to the eye-tracking equipment and the stimulus presentation order. As advancements in generative AI continue to reduce the time and cost of producing highly realistic simulation environments, sustained efforts to integrate 3D model-based simulations into urban design processes are expected to contribute to the development of more efficient and sustainable city-making practices. |
