[Paper] Fast Large-Scale Multi-View Rendering for Coarse Integral Imaging

抄録

High-resolution coarse integral imaging (CII) utilizes a fine-pitch interleaved Fresnel lens array; however, the smaller lens pitch dramatically increases the number of views to be rendered, hindering real-time performance. Moreover, extending the viewing zone requires elemental images to be generated in real time to match the viewer's eye position, making high frame rates indispensable. To address these challenges, we introduce a cluster-level culling technique that accelerates multi-view rendering for CII and sustains real-time frame rates even for scenes with millions of polygons. We further implement the technique in a prototype system on an iPad and an iPhone, both of which achieve real-time performance, demonstrating that CII can be realized with an exceptionally simple mobile-device setup.
