Abstract
Abstract. Recent advances in Terrestrial Laser Scanner (TLS), in terms of cost and flexibility, have consolidated this technology as an essential tool for the documentation and digitalization of Cultural Heritage. However, once the TLS data is used, it basically remains stored and left to waste.How can highly accurate and dense point clouds (of the built heritage) be processed for its reuse, especially to engage a broader audience? This paper aims to answer this question by a channel that minimizes the need for expert knowledge, while enhancing the interactivity with the as-built digital data: Virtual Heritage Dissemination through the production of VR content. Driven by the ProDigiOUs project’s guidelines on data dissemination (EU funded), this paper advances in a production path to transform the point cloud into virtual stereoscopic spherical images, taking into account the different visual features that produce depth perception, and especially those prompting visual fatigue while experiencing the VR content. Finally, we present the results of the Hiedanranta’s scans transformed into stereoscopic spherical animations.

An illustrative case are the multiple websites and free apps announcing the possibility of doing anaglyph from a single image. It is not the purpose of this paper to advance in a regulation/standards for stereo-VR content, we do propose a serious reflection, on the need to advance in responsible selection and consumption of VR content, and the development of knowledge-based content creation processes. This third section summarizes our progress in the development of a practical guideline for the creation of synthetic stereoscopic spherical images based on point clouds
Summary
Laser scanner (LIDAR) technology has been consolidated as an essential tool for the documentation and digitalization of Cultural Heritage sites (Nothegger & Dorninger, 2009). Point clouds are solving a wide range of needs of Cultural Heritage, especially in the areas of conservation and communication, and loads of digital treasures are being captured and stored. Very few reuse alternatives have been implemented for generally unstructured point cloud data, while requiring high memory capacities for both management and storage purposes. How can highly accurate and dense point clouds (of the built heritage) be processed for its reuse, especially to engage a broader audience?
