Abstract:

In order to solve the limitation of auxiliary treatment means in the process of orthopedic trauma surgery, and further improve the effective integration of orthopedic trauma clinical surgery and computer technology, a new orthopedic trauma auxiliary treatment means based on digital orthopedic technology was proposed with the aid of virtual digital technology. The method builds a 3D model of fracture fragments through 3D orthopedic modeling and obtains a high-quality 3D model through processing. Later clinical tests verify the feasibility of this auxiliary treatment method. The test results show that the precision of the 3D reconstruction model based on custom option fitting is higher than that based on optimal option fitting, and the precision difference is within 0.2%. This result also indicates that the 3D model obtained by 3D reconstruction has higher accuracy. The results show that three-dimensional finite element modeling technology can accurately simulate the stress of the spine of orthopedic patients and can reduce the incidence of complications through preoperative diagnosis, curative effect prediction, and trauma surgery, which has a good aid for postoperative recovery.

Abstract:

Monitoring and 3D modeling of an objective can only be done on the basis of high-precision topo-geodetic measurements, but also on the basis of UAV (drone) technologies, thus resulting in an overview of a certain study area. In this context, the present work aims to develop the creation of the 3D model of a grassland surface following a topographic survey by means of GNSS technology and specialized programs. This topographic survey was carried out with the Leica Viva GS07 GNSS equipment, an instrument that contains a wide range of applications. In this work, I used the Real Time Kinematic method to determine the points based on which I created the 3D model in AutoCAD using the TopoLT program. Because the data obtained is complex, in addition to 2D plans, we also have information that can be analyzed in 3D. For studies regarding the shape and the way of exploitation of the land, we created a digital model of the land which is the 3D digital representation of the respective surface. Based on the digital terrain model, we can easily visualize the relief of the grassland, in the present case the minimum altitude is 572.50 m, and the maximum altitude is 590.00 m, with a level difference of 17.5 m over the entire area. This digital terrain model can also be used to model water flow or other geomorphological processes that occur in the analyzed grassland (landslides, erosion, etc.). Multiple longitudinal or transversal profiles can be created over the entire surface to better observe the relief of the land.

Abstract:

Digital repatriation is one aspect of heritage preservation work that has been increasingly gaining popularity due to its effectiveness in assisting Indigenous communities in connecting with museum collections located at various institutions around the world. It is not simply an alternative for physical repatriation; rather, the two can be used in conjunction, particularly with the incorporation of 3D technology. While digital repatriation can provide new opportunities, it is also a contested concept (Boast and Enote 2013) that is still in the process of shaping future collaborative practices while being shaped by ongoing projects and their outcomes. In this paper, we explore how this technology, structure from motion (SFM) 3D modeling and scanning, provides innovative methods that are especially well suited for successfully contributing to a wide array of heritage preservation objectives. Three-dimensional technology is effective in providing alternative ways to connect with collection pieces and providing origin communities access to museum collections. It can alleviate concerns of chemical exposure from contamination, concerns for the fragility of items, the expense of insurance and transportation, or the need to remove pieces from origin communities. As artifacts transform in the repatriation process by gaining new life and meaning when they enter the contemporary reality of the origin community, the use of 3D technology, as part of this collaboration, can assist Indigenous communities in fulfilling their own visions of heritage preservation.

Abstract:

It is essential to have a new understanding of the development of visual sensing technology in digital image art at this stage, in order to make traditional art education have new professional ability teaching. Based on the current research results in related fields, a three-dimensional (3D) image visual communication system based on digital image automatic reconstruction is proposed with two schemes as the premise. In scheme 1, the hardware part is divided into two modules. The hardware used by the analysis of the 3D image layer module is the HUJ-23 3D image processor. The acquisition of a 3D image layer module uses the hardware of a realistic infrared camera. The software of the system consists of two parts: a 3D image computer expression module and a 3D image reconstruction module. A simulation platform is established. The test data of 3D image reconstruction accuracy and visual communication integrity of the designed system show that both of them show a good trend. In scheme 2, regarding digital image processing, the 3D image visual perception reconstruction is affected by the modeling conditions, and some images are incomplete and damaged. The depth camera and image processor that can be used in the visual communication technology are selected, and their internal parameters are modified to borrow them in the original system hardware. Gaussian filtering model combined with scale-invariant feature transform (SIFT) feature point extraction algorithm is adopted to select image feature points. Previous system reconstruction technology is used to upgrade the 3D digital image, and the feature point detection equation is adopted to detect the accuracy of the upgraded results. Based on the above hardware and software research, the 3D digital image system based on visual communication is successfully upgraded. The test platform is established, and the test samples are selected. Unlike the previous systems, the 3D image reconstruction accuracy of the designed visual communication system can be as high as 98%; the upgraded system has better image integrity and stronger performance than the previous systems and achieves higher visual sensing technology. In art education, it can provide a new content perspective for digital image art teaching.

Abstract:

Abstract The emergence of 3D scanning technologies has provided a new opportunity to explore the shape characteristics of hailstones in great detail. The ability to effectively map the shape of hailstones will improve assessments of hailstone aerodynamic properties, how their density relates to their strength, and how radar energy is scattered. Ultimately, 3D scanning of hailstones will contribute toward research in hail detection, forecasting, and damage mitigation of severe hail, which accounts for well over $1 billion in annual insured losses. The use of a handheld 3D laser scanner in a field setting was explored during field campaigns in 2015 and 2016. Hailstones were collected following thunderstorm passages and were measured, weighed, and scanned. The system was successful in capturing 3D models of more than 40 hailstones. A full scan takes approximately 3 minutes to complete, and data can be captured at a resolution of 0.008 cm. It is believed this is the first time such a system has been used to produce 3D digital hailstone models. Analysis of the model data has shown that hailstones depart from spherical shapes as they increase in diameter, and that bulk density and strength show little correlation. While the dataset presented here is small, the use of 3D scanners in the field is a practical method to obtain detailed datasets on hailstone characteristics. In addition, these data could be used to 3D-print hailstones to explore their aerodynamics, to produce cavity molds for ice impact tests, and for modeling radar scattering properties of natural hailstone shapes.

Abstract:

AbstractThree-dimensional (3D) printing is an additive manufacturing method in which a 3D item is formed by laying down successive layers of material. 3D printers are machines that produce representations of objects either planned with a CAD program or scanned with a 3D scanner. Printing is a method for replicating text and pictures, typically with ink on paper. We can print different dental pieces using different methods such as selective laser sintering (SLS), stereolithography, fused deposition modeling, and laminated object manufacturing. The materials are certified for printing individual impression trays, orthodontic models, gingiva mask, and different prosthetic objects. The material can reach a flexural strength of more than 80 MPa. 3D printing takes the effectiveness of digital projects to the production phase. Dental laboratories are able to produce crowns, bridges, stone models, and various orthodontic appliances by methods that combine oral scanning, 3D printing, and CAD/CAM design. Modern 3D printing has been used for the development of prototypes for several years, and it has begun to find its use in the world of manufacturing. Digital technology and 3D printing have significantly elevated the rate of success in dental implantology using custom surgical guides and improving the quality and accuracy of dental work.

This paper aims to present the advantages of using the terrestrial laser scanning technology (TLS) as a method of creating a 3D database and 3D documentation. This state-of-the-art technology is an innovation that has the advantage of acquiring a large amount of data in a short time. This technology together with UAV equipment has the advantage of obtaining a digital terrain model. The creation of 3D patrimony models, archaeological objects and sites in their current state requires specialized equipment, knowledge, and have a powerful methodology capable of digitally capturing and shaping geometric details and fine layout of these sites. Digital recording, documentation and preservation are required because our patrimony (natural, cultural or mixed) suffers from various anthropogenic and/or natural actions (natural disasters, climate change and forgetfulness of human neglect).

However, the conventional cement mortar is not suitable for 3D-printing, Because that its aggregate ingredients may cause the cracks in the process of printing. Moreover, the buildability and rheological properties of conventional mortar cannot reach the requirements of 3D-ptinting concrete technology. Ultra-high performance concrete is a developing category of material used in concrete structures and it is considered to be one of the most appropriate printing materials. As the popularization of computer technology, it is a necessary task to research on the digital construction way of concrete structures. And 3D-printing concrete technology combines the popular topics above together. This study mainly introduces the fabrication process of ultra-high performance concrete and digital printing process of 3D-printing concrete, and the mechanical properties of printed specimens are studied by the experimental results.

Abstract:

Digital sculpture is an emerging sculpture form. The current digital sculptures are dominated by abstract modeling and digital sculpture should also be conducted by simulating the method of traditional realistic sculpture. 3d printing technology still lacks application experience in making large-size digital sculptures, while digital controlled sculpting technology has some limitations for sculpture modeling. In instantiation of works, how to maintain digital characteristics of digital sculpture is an issue that requires in-depth discussion in the field of digital sculpture. 3d scanning technology has realized transition from traditional sculpture to digital sculpture and changed the method in which digital sculpture depends on software.

Abstract:

HBIM technology makes great contributions to 3D digital preservation and management of the existing traditional architectures, and VR technology has also been gradually emphasized by 3D users in recent years, especially 3D immersive situation makes users more likely to experience the real space field. Taking Han type traditional architecture with relatively complex geometrical structure as an example, this research carries out digital preservation through HBIM technology and tries to switch to VR platform to allow users to enter 3D immersive scene for management and display. It is shown in the research results that the application of integration of HBIM and VR technology to Han type traditional architecture needs to consider 3D digital model of the architecture, and the number of polygon shall be controlled below about 2 million, which can make the operation in VR environment more smooth; the integration of two technologies can achieve the purpose of 3D immersive digital management, which can provide the humanized application close to the real experience for the display of subsequent management of ancient relics and architectural aesthetics.

Abstract:

The combination of lidar and digital photography provides a new technology for creating a high-resolution 3D digital outcrop model. The digital outcrop model can accurately and conveniently depict the surface 3D properties of an outcrop profile, making up for the shortcomings of traditional outcrop research techniques. However, the advent of digital outcrop poses additional challenges to the 3D spatial analysis of virtual outcrop models, particularly in the interpretation of geological characteristics. In this study, the detailed workflow of automated interpretation of geological characteristics of fractures and cavities on a 3D digital outcrop texture model is described. Firstly, advanced automatic image analysis technology is used to detect the 2D contour of the fractures and cavities in the picture. Then, to obtain an accurate representation of the 3D structure of the fractures and cavities on the digital outcrop model, a projection method for converting 2D coordinates to 3D space based on geometric transformations such as affine transformation and linear interpolation is proposed. Quantitative data on the size, shape, and distribution of geological features are calculated using this information. Finally, a novel and comprehensive automated 3D quantitative characterization technique for fractures and cavities on the 3D digital outcrop texture model is developed. The proposed technology has been applied to the 3D mapping and quantitative characterization of fractures and cavities on the outcrop profile for the Dengying Formation (second member), providing a foundation for profile reservoir appraisal in the research region. Furthermore, this approach may be extended to the 3D characterization and analysis of any point, line, and surface objects derived from outcrop photos, hence increasing the application value of the 3D digital outcrop model.

Abstract:

IC technology, which has traditionally been dominated by dimensional scaling, is facing several technical and economic hurdles as it moves forward. Low K insulation has not been able to meet performance projections, copper traces are becoming more and more resistive, clock rates have been constrained due to thermal issues and multicore processors are demanding major increases in bandwidth and decreases in latency. Economic constraints will also begin limiting the number of IC companies able to develop leading-edge IC designs. Moving past 45 nm digital CMOS scaling will no longer guarantee lower cost and higher performance. All of these issues have crated a “perfect storm scenario” for the widespread adoption of 3D IC technology.

Abstract:

This article discusses how to sculpt digitally with ZBrush software. This is a new trend in film, gaming, and animation industry using 3D modelling software like ZBrush. ZBrush is a digital sculpting tool that combines modeling 3D/2.5D, texturing, and painting. The use of a technology called Pixol on the software allows deep storage of lighting, color, and material information in an object in the layer. Moreover, the technology differs Zbrush with other 3d modeling softwares which are more traditional because the software is more like sculpting. Zbrush as a digital sculpting tool is capable of making high-resolution models (up to ten million polygons). The Zbrush capability at the level of high resolution and detail level can be set dynamically, allowing the user to make changes in total or in part on the carvings. Stages described in the article in addition to explain the function of the tool, are also the advantages that exist in ZBrush software compared to other 3d softwares. Sample images from various sources and some projects may help the reader know and understand the Zbrush software and bridge the manual artist to digital 3d artist as well.

It is shown that currently there are no defined standards for 3D scenes construction technologies that could be used by Russian surveying and cartographic enterprises. The issues regarding source data requirements, their capture and transferring to create 3D scenes have not been defined yet. The accuracy issues for 3D video scenes used for measuring purposes can hardly ever be found in publications. Practicability of development, research and implementation of technology for construction of 3D video scenes is substantiated by 3D video scene capability to expand the field of data analysis application for environmental monitoring, urban planning, and managerial decision problems.

Abstract:

Recognising the relevance of learning Geometry, and in particular 3D Geometry, this study aims to discuss the contributions that digital technology and paper and pencil approaches can bring to students’ learning. We seek, therefore, to identify the differences between the two approaches, and specifically: What factors are relevant in one and the other approach? What does one approach facilitate over the other? A quantitative and a qualitative and interpretive methodology was adopted, and based on a didactic intervention, the students' resolutions of the proposed tasks were analysed. The results obtained show that the experience and prior knowledge of the students with each of the solids involved seems to be decisive in the approach with paper and pencil. However, technology emerges as an enhancing resource when prior knowledge is more fragile. The study also shows differences between the representations supported by the two resources, suggesting the mobilisation of different knowledge by the students in relation to each of the resources.Recognising the relevance of learning Geometry, and in particular 3D Geometry, this study aims to discuss the contributions that digital technology and paper and pencil approaches can bring to students’ learning.

Abstract:

In order to obtain the complete color point cloud data of traditional ceramic artworks and reconstruct them efficiently, a 3D digital reconstruction method of ceramic painting products based on virtual reality technology was proposed. By the method, the 3D color point cloud data of ceramic works were collected by the camera 3D scanning equipment. The new postprocessing methods such as fusion and repair were investigated and proposed so as to obtain the complete optimized color point cloud information. The high-fidelity 3D mesh model and simplified mesh of ceramic artworks were obtained through the mesh process and the digital display platform was developed by using virtual reality technology. The experiment results showed that the 3D color point cloud data of traditional ceramic artworks were obtained by +5 exposure blend methods on average in the 6 combined modes and point cloud optimization and repair were completed. High-precision color mesh model was generated and digital promotion and publicity were carried out. The proposed 3D reconstruction technology and virtual display method made a positive exploration for the protection, inheritance, and promotion of China’s ceramic artworks and made a new attempt for the digital protection of cultural heritage by using modern science and technology.

Abstract:

Abstract Recent advances in additive manufacturing enable redesigning material morphology on nano-, micro-, and meso-scale, for achieving an enhanced functionality on the macro-scale. From non-planar and flexible electronic circuits, through biomechanically realistic surgical models, to shoe soles individualized for the user comfort, multiple scientific and technological areas undergo material-property redesign and enhancement enabled by 3D printing. Fiber-device technology is currently entering such a transformation. In this paper, we review the recent advances in adopting 3D printing for direct digital manufacturing of fiber preforms with complex cross-sectional architectures designed for the desired thermally drawn fiber-device functionality. Subsequently, taking a recursive manufacturing approach, such fibers can serve as a raw material for 3D printing, resulting in macroscopic objects with enhanced functionalities, from optoelectronic to bio-functional, imparted by the fiber-devices properties.

Abstract:

Computational design allows for architecture with an extraordinary degree of topographical and topological complexity. Limitations of traditional CNC technologies have until recently precluded this architecture from being fabricated. While additive manufacturing has made it possible to materialize these complex forms, this has occurred only at a very small scale. In trying to apply additive manufacturing to the construction of full-scale architecture, one encounters a dilemma: existing large-scale 3D printing methods can only print highly simplified shapes with rough details, while existing high-resolution technologies have limited print spaces, high costs, or material attributes that preclude a structural use. This paper provides a brief background on additive manufacturing technology and presents recent developments in sand-printing technology that overcome current 3D printing restrictions. It then presents a specific experiment, Digital Grotesque project, which is the first application of 3D sand-printing technology at an architecture scale. It describes how this project attempts to exploit the potentials of these new technologies.
