Chakai-ki is a chronicle of Japanese tea utensils and confectioneries. It is based upon the experiences garnered during tea ceremonies and constitutes a significant aspect of the rich 490-year history of Japanese tea ceremony culture. We propose to create a three-dimensional ver. archive of Chakai-ki, which has been relegated to mere textual records, by meticulously recreating the intricate visual aesthetics produced by the utensils and confectioneries.
Our framework, NeARportation, reproduces the visual aesthetics in tea utensils and confections, such as the patterns of glaze and the transparency of agar. Comprised of Neural Radiance Fields (NeRF), a deep learning-based free viewpoint image generation, and a naked-eye 3D stereoscopic display, our framework delivers real-time 3D stereoscopic images of objects according to the observer's perspective. This technology has the potential to foster a revitalized tea ceremony culture by transforming tea ceremony records, which possess a wealth of historical and cultural significance, into a rich repository of reusable visual information.
