3D modelling is an important way in simulating of historical building. Modelling methods based on laser-scanned data and automated image-based techniques are commonly used recently. In this paper, modelling method based on parametric description is proposed. One prominent feature of traditional Chinese architecture is its modular system. By studying typical structures and components of Chinese traditional buildings, parameters of different structures are summarized and simplified to establish the reasonable model. Then, the process of programming a 3D modelling system using 3DSMax script language is discussed. Through this method, after choosing the type of traditional buildings and entering necessary parameters, 3D model with different type and size can be created automatically and efficiently. The research of this paper could provide a new way of establishing 3D model for building’s virtual reconstruction and walkthrough.

With the flexibility and modularity of the construction system, the ancient Chinese architecture was a configurative system until the modern time when it became figurative with nationalistic symbolism, and lost its flexibility to adapt in different functions. Through this study, the researchers try to exploit and release the powerful adaptation of this configurative system by using the method of parametric design. First of all, according to the modern parametric theory, the logic of the traditional structural system is found out by abandoning the feudal social hierarchical factors. And then, a 3D model of parametric structure with wide adaptability is established in Rhino by using its parametric design plug-in Grasshopper. Finally, on the basis of the modern parametric skin theory, two skin systems are attached to this new structure separately, in order to prove the feasibility of the new skin idea to this structure. Through the introduction of parametric modeling steps, this paper focuses on mining the modern adaptability of Chinese traditional architecture.

Abstract. The paper presents a practical approach to define a hypothetical virtual reconstruction of the ciborium and pergola of Monte Sorbo's Church. The high accuracy of archaeological fragments, digitally acquired, allowed to hypothesize the entire sequences of decorations of architectural elements and to define their geometrical rules. Starting from the acquisition to the 3d modelling phase, the proposed virtual reconstruction combines original fragments with their lost parts modelled in a digital environment.Digital technologies offer nowadays the great possibility to visualize and understand cultural heritage in a new and attractive way. Digital models and virtual reconstructions have a key role in encouraging and promoting the development of good practices for recording, documenting, and making accessible scientific processes beyond visual appearance. The term virtual reconstruction, within the project, is used to describe a procedure that consists of making a 3D model that reproduces a digital copy of the original, assembling digitally acquired fragments with elements philologically reconstructed following the evidence-based geometrical rules. This study aims to contribute to this growing area of research by exploring possibilities on digital integration of different 3d models to re-define a visual appearance of lost architectural elements.

<p><strong>Abstract.</strong> The three-dimensional (3D) documentation and surveying of cultural heritage can be carried out following several geomatics techniques such as laser scanning and thermography in order to detect the original 3D shape after applying reverse engineering solutions. In almost all cases, the integration of data collected by different instruments is needed to achieve a successful and comprehensive 3D model of the as-built architectural shape of the historical building. This paper describes the operations carried out by the authors to determine the as-built 3D model of the Escuelas Pias Church, related namely to the dome and circular nave. After the description of the church and historical notes, attention will be driven to the indirect registration results obtained with three different laser scanning software packages, highlighting similarities and differences, and the consequences while generating meshes. The 3D model carried out will then be described and the results of some investigations with regard to the hypotheses about the design of the dome and the origin of the alterations will be presented.</p>

The present article provides an overview of the main methods of three-dimensional modelling currently used in various fields of science and practice, including forensic medicine. The possibilities of used methods are described.The authors introduce the concept of BIM-technology, which allows various methods working in 3D to be applied comprehensively: from photogrammetry and computed tomography to line-of-sight and CAD modelling. The article presents a case involving practical application of BIM-technology within the practical work of a forensic expert. The possibilities of supplementing and expanding the model over time within a single information field (4D modelling) are shown.Using the example of a specific examination, it is shown for which studies the created BIM-model can be employed, as well as what issues can be solved with its help. To that end, CT data was studied with the subsequent reconstruction of the 3D model of the damaged skull; blood traces were analysed with the subsequent 3D modelling of circumstances at the scene. The following methods were used for the reconstruction: photogrammetry, the finite element method and line-of-sight modelling of gunshot trajectories.Applied within a situational forensic medical examination, BIM-technologies successfully provided answers to the investigator’s questions: mechanism underlying the formation of blood traces; location of the bleeding source; trajectories of projectiles and their elements; circumstances of the occurrence; position of the shooter; prediction of glass breakage caused by a bullet.Conclusion. New computer technologies (BIM-technology and 4D modelling) constitute the next step in the development of three-dimensional modelling. Their introduction into the practice of experts will help create a single information field for all objects under study, as well as consider all possible investigative leads as objectively as possible

During the last years the softwares and applications that can produce 3D models using low-cost methods have become very popular. What is more, they can be successfully competitive with the classical methods. The most wellknown and applied technology used to create 3D models has been laser scanning so far. However it is still expensive because of the price of the device and software. That is why the universality and accessibility of this method is very limited. Hence, the new low cost methods of obtaining the data needed to generate 3D models appeare on the market and creating 3D models have become much easier and accessible to a wider group of people. Because of their advantages they can be competitive with the laser scanning. One of the methods uses digital photos to create 3D models. Available software allows us to create a model and object geometry. Also very popular in the gaming environment device – Kinect Sensor can be successfully used as a different method to create 3D models. This article presents basic issues of 3D modelling and application of various devices, which are commonly used in our life and they can be used to generate a 3D model as well. Their results are compared with the model derived from the laser scanning. The acquired results with graphic presentations and possible ways of applications are also presented in this paper.
