“…The focus is now to evolve from the first steps of observation (creating digital representations of the artworks under study) to the design and use of tools to support the investigation of scholars working over digital representations [SCC*11]. Therefore, annotation remains a common feature of many CH tools or systems [SSRS12, HG10, AAB*14]. Semi‐automatic methods have been proposed to annotate collections of artworks, adding semantic metadata by means of an automatic, suggestion‐driven process [FKW17] or by adopting harvesting methods able to collect and integrate community annotations [HG10].In the domain of artwork restoration, the analysis of the conservation status, the planning of the restoration action or its post‐execution documentation are usually implemented by the production of complex maps, where the surface of the artwork is characterized and described in detail [ABC*18], leading to very complex annotation patterns (see Figure bottom). Archives of 3D models : With the advent of easy‐to‐use 3D digitization and digital fabrication technologies, a number of web‐based archives for 3D models appeared.…”

Annotation support in interactive systems is often considered a simple task by the CG community, since it entails the apparently easy selection of a region and its connection with some information. The reality appears more complex. The scope of this paper is two‐fold: first, to review the status of this domain, discussing and characterizing several approaches proposed in literature to manage annotations over geometric models; second, to present in detail an innovative solution proposed and assessed in the framework of Cultural Heritage (CH) applications, called ClippingVolumes. At the annotation definition stage ClippingVolumes uses 3D data to characterize the annotation region; subsequently, annotations are visualized by adopting a two‐pass rendering solution which uses stencil buffers, thus without introducing new geometric elements, changing the topology or duplicating geometry elements. It solves most of the issues that afflict the current state of the art, such as fragmentation, annotation transfer to multiple representations and multi‐resolution data encoding. The latter is a mandatory requirement to produce efficient web‐based systems. We implemented and we fully tested this approach in the framework of a complex system that supports the documentation of CH restoration projects.

“…In the museums context, another system assisted by ontologies that aims the collaborative annotations of 3D museum artifacts through web-based services, was proposed (Hunter and Gerber, 2010). This system -entitled Harvesting and Aggregating Networked Annotations (HarvANA) -promotes the participation of communities in the cultural enrichment and improves museum objects indexation.…”

“…They have been successfully applied in different solutions that require the use of virtual models/environments (Lee et al, 2008a;Attene et al, 2009;Hunter and Gerber, 2010) to achieve a wide variety of purposes that range from the planning of neurosurgery operation to the cataloguing of museum artefacts. A few procedural modelling solutions also used them to guide the process of generating virtual models (Liu et al, 2008;Trescak et al, 2010;Tutenel et al, 2011).…”

University of Trás-os-Montes e Alto Douro Albert EinsteinTo my family and friends To my soulmate Dércia vii UNIVERSITY OF TRÁS-OS-MONTES E ALTO DOURO PhD in Computer ScienceThe members of the jury recommend to the University of Trás-os-Montes e Alto Douro the acceptance of the thesis entitled "Ontology-based Procedural Modelling of Traversable Buildings Composed by Arbitrary Shapes"accomplished by Telmo Miguel Oliveira Adão in partial fulfillment of the requirements for the degree of Doctor Philosophy. December 2015Jury President:Professor Abstract -3D virtual models of buildings are commonly used in areas such as architecture and video games to preview a house project and to populate a virtual scenario, respectively. Traditionally, the production of these models requires highly skilled manpower and a considerable amount of time. To address this issue, many researchers have developed semi-automatic techniques to produce virtual models expeditiously. These procedural techniques provide different ways of generating buildings, including interiors and outer facades, to serve several purposes (e.g., content generation for video games or archaeological reconstruction). However, the existing techniques focusing on building interiors usually only support the generation of floor plans constrained by regular shapes or contour polygons obtained from rectangles sets. At the same time, the possibility of modelling interior rooms through the specification of its constraint walls remains poorly explored. Moreover, most of the existing procedural generation solutions are guided by complex grammars concerned with geometrical aspects or semantic structures that fit specific project requirements, apparently disregarding the established standards for virtual urban environments, specifically, CityGML.To overcome the noted issues, a novel procedural modelling methodology is proposed in this thesis, one that produces virtual models of buildings, including exteriors outlined by arbitrary shapes and interiors formed by convex polygons. Methodology's regulation is provided by a building ontology -a CityGML-based knowledge structure, planned to be extensible to specific architecture styles -through several guiding data structures such as structured XML and ontology-based grammar. Regarding the supporting process, a treemap approach is used to subdivide the building layout into floor plan areas. During the development of this work, several improvements were progressively made to the treemap in order to enable the subdivision of different constraint polygon types which range from rectangles to arbitrary shapes. Moreover, in the most mature work stage, a method concerning inner room walls adaptation is addressed. Next, a set of operations is performed, from the marking transitions step to the extrusion process that provides the 3D aspect. In addition, an experimental stochastic approach is proposed to automate the production of random buildings using this procedural modelling methodology.A set of tests was made to demonstrate the capabilitie...
