    Bidirectional Exploration of 3D Cultural Heritage Models and Photo Collections

    Advances in 3D digitization have greatly improved the availability of high-quality cultural heritage datasets, often consisting of 3D models and collections of high-resolution photos. However, navigating these 3D datasets poses challenges for art history researchers, especially when they need to repeatedly locate points of interest, get close-up views of them, and analyze their spatial relationships. Existing applications for 3D model sharing often fail to provide a convenient interface to simultaneously explore the 3D model and associated photo collections. This paper proposes a web-based approach that combines a 3D view of the model with a 2D view of a group of photos. Designers can quickly arrange groups of images into 2D projections, and cultural heritage users can explore the 3D model and, simultaneously, the active group of images in the 2D view. Both views are interlinked, so that navigating the 3D model modifies the active photo group, and clicking an image in the 2D view moves the 3D camera to the 3D position the image was taken from. We tested our approach with a 3D dataset on medieval mural paintings. Our tests show that our method helps users quickly locate, inspect and relate different parts of the model, reducing navigation time and frustration.
