Virtual Inspector: A Flexible Visualizer for Dense 3D Scanned Models

The rapid evolution of automatic shape acquisition technologies will make huge amount of sampled 3D data available in the near future. Cultural Heritage (CH) domain is one of the ideal fields of application of 3D scanned data, while some issues in the use of those data are: how to visualize at interactive rates and full quality on commodity computers; how to improve visualization ease of use; how to support the integrated visualization of a virtual 3D artwork and the multimedia data which tell its story. We present here the Virtual Inspector tool. The system allows naive users to inspect a very dense 3D model at interactive frame rates on offthe-shelf PC's, presenting the 3D model and all the multimedia data that has been linked to selected points of its surface. A main goal in the design of the system was to provide the user with a very easy and natural interaction approach, based on a straightforward "point and click" metaphor. Visualization efficiency is obtained, wi...
