CREATING, VISUALIZING AND SHARING HIGH-POLY AND MULTI-TEXTURES MODELS ON THE WEB

Abstract. In many Cultural Heritage cases study, where usually the shapes to be reproduced have complex and irregular geometries there is a growing demand to create and use very high-resolution polygonal models that represent the real objects with great accuracy and level of detail. In archaeological field, for example, it is fundamental to create a virtual reconstruction that is as close as possible to the reality, because the digging operations are often destructive and it is necessary to track and preserve for the future as much as possible. This requirement leads to three relevant problems: 1) the elaboration of high-poly and high-resolution models, 2) the management of these models, 3) their sharing and access. In this paper, both a scientific approach for realizing the accurate and detailed models and a system to manage, share and visualize these models on the web will be shown. Moreover, a multi-texture digital model elaboration is proposed for the correct definition of the geometrical and texture resolution in relation to the survey level of detail, the physical size of the object and the project requirement. In particular, a web-system that allows the sharing of very high-resolution models, with multi-textures support will be presented.
