Abstract
Usually the diffusion and sharing of cultural heritage documented 3D models on the web are not first of concern for scholars due to the fear of losing the intellectual property related to them. Sometimes the interaction and navigation of virtual objects via the World Wide Web is also problematic due to their dimension (number of triangles), when high-definition has to be preserved. In this paper we propose a mash up methodology, for a multiple approach to visualize 3D models over the internet. After the digitization of a marble statue placed in the Medieval Museum of the city of Bologna, according to the well known 3D pipeline (from the laser scan survey to the texturing process), we assembled together different solutions for sharing the model on the web.
Highlights
Today it should be possible for an end-user to take advantage of web resources to view high-definition 3D models of cultural heritage artifacts and monuments
The parameters intended to be preserved for this study were: real time interaction; definition/quality; intellectual rights attached to the model
Aside from the remote rendering technique, all other approaches showed a lack in definition, interaction and/or intellectual rights preservation, separately or together
Summary
Today it should be possible for an end-user to take advantage of web resources to view high-definition 3D models of cultural heritage artifacts and monuments. This should be possible online and in real time without a browser plug-in. The model was texturized using the UV modifier of 3D Studio Max 9 software. After all the post-processing steps the 3D high-definition model of the “Acquasantiera” consists of 6 million triangles plus the texture information (Figure 2). It was possible to decimate the model significantly, the largest amount of triangles was preserved in order to save the high quality and details of the object
