abstract = {The paper presents a novel solution to the issue of incomplete regions in 3D meshes obtained through digitization. Traditional methods for estimating the surface of missing geometry and topology often yield unrealistic outcomes for intricate surfaces. To overcome this limitation, the paper proposes a neural network-based approach that generates points in areas where geometric information is lacking. The method employs 2D inpainting techniques on color images obtained from the original mesh parameterization and curvature values. The network used in this approach can reconstruct the curvature image, which then serves as a reference for generating a polygonal surface that closely resembles the predicted one. The paper’s experiments show that the proposed method effectively fills complex holes in 3D surfaces with a high degree of naturalness and detail. This paper improves the previous work in terms of a more in-depth explanation of the different stages of the approach as well as an extended results section with exhaustive experiments.},

abstract = {Andalusia is an autonomous region in southern Spain with 10 public universities, of which two date back to the 16th century: the University of Seville (1505) and the University of Granada (1531). Some have all their buildings and offices in a single campus, such as the University of Almeria and the
University of Huelva, while others are distributed among several campuses in a city or even in several cities separated by hundreds of kilometers. We can thus consider the cultural heritage of Andalusian universities to be a geographically distributed collection, impossible to visit in one go. In this paper, we will present and discuss Atalaya3D, a collaborative project that aims to make this cultural heritage accessible to the public. It consists of a virtual platform (web and app) that uses the most recent advances in the field of 3D scanning, 3D web displays and a mobile app to enable the exploration of these institutions’ vast heritage in a 3D environment before (or without) visiting the campus. Since 2010, more than one hundred artworks and historical buildings have been accurately scanned using the latest 3D scanning and photogrammetric technologies resulting in, not only the promotion of the university heritage to large audiences, but also in the precise documentation of geometry, architecture and color. In-place visitors can obtain a better experience by obtaining extra information from the mobile app, easily triggered by reading QR codes. Moreover, the usage of social media expands and disseminates the advances, results, and contents of the project. },

abstract = {In this paper, we address the problem of collision detection between very high resolution polygonal models. We propose an approach that uses the EBP-Octree data structure in a single-core CPU architecture. The algorithm manages a set of files to support a cache-like out-of-core algorithm that performs the collision and intersection tests. Our method uses a data structure called EBP-Octree (Extended Bounding-Planes Octree), which is a very tight hierarchy of convex bounding volumes that, based on a spatial decomposition of the model using an octree, defines a bounding volume at each node by a subset of the planes of the portion of polygonal model contained at that node. The system adapts the memory consumption to the system’s hardware features so it can provide exact triangle collision detection in almost any environment, since the amount of information in the main memory can be limited just varying the threshold of the EBP-Octree. We have tested the data structure and the algorithm in scenarios where two models of 28 million polygons move through one another, achieving real time frame rates for first collision tests on a commonly available computer.},

Moreover, in addition to the website, a mobile app allows visitors to browse these institutions’ vast heritage and examine it before visiting the campus in a 3D environment. More than 70 artworks and historical buildings have been accurately scanned using the latest 3D scanning technologies, so that we now have the geometry and colour of the pieces documented in detail.

abstract = {Cultural heritage (CH) documentation tasks usually involve professionals from different knowledge areas, which implies not only a huge amount of information and requirements, but also a very heterogeneous set of sources, data structures, content and formats. Geographic information systems (GIS) have been used extensively by cultural heritage specialists, but this is just working around the real problem: there is no specialized software for CH professionals to document their work in 3D. In this paper, we present software named Agata that allows specialists to interact in real time with high resolution polygonal models, and to annotate different raster and vectorial information directly onto them that might be useful for current or future research. Moreover, these annotations can be exported in a standard format that allows researchers from other disciplines that might be interested in the dataset to access such information easily. The system is able to manage and annotate not only on buildings or archaeological sites, but also sculptures or paintings directly into the 3D dataset of any CH physical element.},

Furthermore, the user can add to the scene a list of cameras with their respective control points, and then generate several routes through the scene. The scene is rendered in the browser using standard technologies, such as WebGL (ThreeJS) and X3D (X3DOM), and the mobile app is generated via Unity3D . Also, the X3D and MPEG-4 compression standards allow us to transform the scene and its camera routes into 360 videos, where user can manipulate camera orientation while playing the track. Also, audio tracks can be added to each route and hence, inserted in the 360-degree video.},

Unfortunately, existing haptic rendering or collision detection toolkits cannot handle polygonal models obtained from 3D digitized point clouds unless the models are simplified up to a few thousand polygons, which leads to an important lack of detail for the scanned pieces. We propose a data structure that is able to manage very large polygonal models (over 25M polygons), and we explain how this can be used in order to compute the inclusion of a point into the solid surface very efficiently, performing several thousand point-in-solid tests per second. Our method uses a data structure called EBP-Octree (Extended Bounding-Planes Octree), which is a very tight hierarchy of convex bounding volumes. Based on a spatial decomposition of the model using an octree, at each node it defines a bounding volume using a subset of the planes of the portion of the polygonal model contained at that node. We use the EBP-Octree in a haptic interaction environment, where distance tests and the orientation of collided triangles must be accurate and fast. We also demonstrate that the proposed algorithm largely meets the interactive query rate demanded by a haptic interaction (1 kHz), despite being executed in a single CPU thread on a commonly available computer.},

The Extended Bounding-Planes Octree (EBP-Octree) is able to manage massive polygonal models by using a spatial indexation of the surface and storing a hierarchy of bounding volumes composed of planes from the original surface. In this work we detail the geometric and design criteria that have been considered in order to create, just once for each model, an out-of-core data structure that will be dynamically loaded in run-time while traversing the octree in environments such as collision detections of progressive transmission. Due to the applications that might use this data structure, the main goals are to obtain a tight volume at each node and a fast transition among disk and main memory while loading and releasing the octree branches.

The BP-Octree is based on a spatial decomposition of the model using an octree, and offers a very tight hierarchy of convex bounding volumes which leads to simplified models.

These planes are taken from the real polygons of the model, and are selected at each level guaranteeing that they include completely all boundings of deeper levels.

However, at intermediate levels of the SP-Octree, the obtained visualisation is a rough approximation of the object due to the fact that grey nodes are approximated by the face's planes belonging to the convex hull of the solid included in that node.
In this paper, we present an approach that improves the visualisation of these multiresolution SP-Octrees models by applying impostors over those planes that are not part of the solid boundary. This way, it is possible to obtain a more realistic visualisation of the object, although the maximum LOD is not used. At each moment, the impostor is selected depending on the observer's viewpoint. Each SP-Octree has associated a set of impostors that are views of the modelled complex solid.},

Nonetheless, the SP-Octree is a solid modeling structure, intended to solve problems as solid intersections and point inclusion tests. At intermediate levels of the SP-Octree, the visualization is a rough approximation of the object due to the fact that grey nodes are shown as the convex hull of the part of the solid included in that node.
In this paper we present an approach to use SP-Octrees for adaptative visualization, that improves the visualization of these multiresolution models by applying impostors over those planes of the hierarchical structure that belongs to the convex hull but are not part of the solid boundary (ficticious planes). By doing so, it is possible to obtain a better approximating visualization of the object, although the maximum LOD is not used. At every moment, the impostor is selected depending on the viewpoint.},

To get the appropriate orientation, the archaeologist selects some areas of the border. A genetic algorithm is then applied to the points on these areas obtaining the plane that best fits the border of the fragment.
The profile of the vessel is also interactively chosen by the expert, who draws it on the fragment as in a graphical editor. This profile is also editable, it being possible to eliminate, move or insert points. From this information, the system generates the unknown part of the profile using splines. Finally, the system makes it possible to create a 3D virtual view of the complete vessel and the traditional 2D drawing, such that it can be edited (i.e. by positioning the original fragment or placing measurement lines).
The software is very efficient, enabling the creation of the drawings in a few minutes.},

abstract = {Every archaeological excavation must deal with a vast number of ceramic fragments. The documentation, administration and scientific processing of these fragments represent a temporal, personnel, and financial problem. Up to now documentation and classification have been done manually which means a lot of routine work for archaeologists and a very inconsistent representation of the real object. First, there may be errors in the measuring process (diameter or height may be inaccurate). Second, the drawing of the fragment should be in a consistent style, which is not possible since a drawing of an object without interpreting it is very hard to do. We are developing a documentation system for archaeological fragments based on their profile, which is the cross-section of the fragment in the direction of the rotational axis of symmetry. Hence the position of a fragment (orientation) on a vessel is important, since it allows a good profile to be obtained. This paper presents two different approaches to the estimation of the orientation of archaeological fragments and the profile extraction. One method is based on a Hough inspired approach and the other is based on genetic algorithms and expert interaction. We compare the methods and show results with respect to robustness, applicability, and accuracy.},
