Remote rendering and visualization of large textured 3D models

There is an increasingly urgent need, expressed by the scientific community and by the end users, to exploit web resources in order to analyse, process, visualize and interact remotely and in real time with 3D high definition models of Cultural Heritage artefacts and monuments. Many sharing platforms are currently developing thanks to user contributions. However this goal has not been yet reached successfully. Complex mesh models cannot be displayed interactively online on consumer computers, without downloading locally the entire model or accepting the compromise solution that the model is blurred and fuzzy during the interaction. Thus a key aspect is the quality with which the content is “distributed”, and, at the same time, the certainty of copyright protection. The platform implemented and here presented allows an efficient and effective multi-user online sharing of high quality 3D textured models without the need for the users to download it locally but exploiting the performances of a remote HPC infrastructure.
