Urban underground space planning based on FPGA and virtual reality system

摘要

The underground plaza is a place of leisure activities for citizens, represents the quality of the city's underground space, experience, so the space is significant. The present study of the ten large-scale urban underground space of the study summarized the essential elements and the underground plaza of the corresponding numerical interval's interface form. It describes the interface format's spatial experience of influence an underground plaza; on this basis, the underground plaza virtual model is built in a different interface format. The isovist method and the SD method to comb the Immersive Virtual Reality System (IVRS) platform, the shape of the interface and spatial experience, and the correlation between the related compliance indicators proposed interface form are quantitative analysis. It is summarized. Experimental results, spatial experience have indicated better at 0.402 interface density and interface 2-3 aperture aspect ratio. This is, it can become a reference and basis for the future of urban underground space design.
