We introduce a novel user interface and system for exploring extremely detailed 3D models in museum setting. Three-dimensional associated information are presented on large projection surface controlled by touch-enabled placed at suitable distance front of it. Our indirect interface, dubbed IsoCam , combines an object-aware interactive camera controller with point-of-interest selector is implemented within scalable implementation based multiresolution structures shared between the rendering interaction subsystems. The collision-free automatically supports smooth transition from orbiting to proximal navigation, exploiting distance-field representation object. exploits specialized view similarity computation propose few nearby easily reachable interesting views database, move user-selected point interest, provide extra through overlaid annotations target view. capabilities our approach have been demonstrated public event attended thousands people, which were offered possibility explore submillimetric reconstructions 38 stone statues Mont’e Prama Nuragic complex, depicting larger-than-life human figures, small prehistoric Nuraghe (cone-shaped towers). A follow-up this work, using 2.5m-high screens, now included permanent exhibitions two Archeological Museums. Results thorough evaluation, involving quantitative subjective measurements, discussed.
