Abstract:

UAV (Unmanned Aerial Vehicle) photogrammetry, which combines UAV and freely available internet-based 3D modeling software, is widely used as a low-cost and user-friendly photogrammetry technique in the fields such as remote sensing and geosciences. In UAV photogrammetry, only the platform used in conventional aerial photogrammetry is changed. Consequently, 3D modeling software contributes significantly to its expansion. However, the algorithms of the 3D modelling software are black box algorithms. As a result, only a few studies have been able to evaluate their accuracy using 3D coordinate check points. With this motive, Smart3DCapture and Pix4Dmapper were downloaded from the Internet and commercial software PhotoScan was also employed; investigations were performed in this paper using check points and images obtained from UAV.

Abstract:

The article provides an analysis of modern and affordable software systems for modelling shells of complex geometry and the possibilities of using these software systems in 3D printing. Such an analysis made it possible to choose software systems that most accurately allow for the implementation of the 3D modeling method proposed in the article with subsequent printing on a 3D printer. This method is considered in detail on the example of constructing several types of helicoids. The process of 3D modeling of a helicoid is described step by step and is divided into several stages: parametric modeling of a helicoid in SCAD, editing of the resulting model in AutoCAD and its export to a special format for 3D printing. The use of the method of parametric modeling is due to its accuracy and uncompromisingness. With its help, one can accurately judge the type of the built surface. Parametric modeling is the construction of a surface by compiling equations on each axis, i.e. along the x, y, z axes, and for each type of surface there are specific characteristic equations. It is not possible to implement the method of parametric modeling in all software systems; in this connection, certain difficulties arise. The article analyzes the difficulties encountered in 3D modeling of the helicoid and suggests ways to solve them.

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.

Abstract:

3D city model is a digital representation of the Earth’s surface and it’s related objects such as building, tree, vegetation, and some manmade feature belonging to urban area. The demand of 3D city modeling is increasing rapidly for various engineering and non-engineering applications. Generally four main image based approaches were used for virtual 3D city models generation. In first approach, researchers were used Sketch based modeling, second method is Procedural grammar based modeling, third approach is Close range photogrammetry based modeling and fourth approach is mainly based on Computer Vision techniques. SketchUp, CityEngine, Photomodeler and Agisoft Photoscan are the main softwares to represent these approaches respectively. These softwares have different approaches & methods suitable for image based 3D city modeling. Literature study shows that till date, there is no complete such type of comparative study available to create complete 3D city model by using images. This paper gives a comparative assessment of these four image based 3D modeling approaches. This comparative study is mainly based on data acquisition methods, data processing techniques and output 3D model products. For this research work, study area is the campus of civil engineering department, Indian Institute of Technology, Roorkee (India). This 3D campus acts as a prototype for city. This study also explains various governing parameters, factors and work experiences. This research work also gives a brief introduction, strengths and weakness of these four image based techniques. Some personal comment is also given as what can do or what can’t do from these softwares. At the last, this study shows; it concluded that, each and every software has some advantages and limitations. Choice of software depends on user requirements of 3D project. For normal visualization project, SketchUp software is a good option. For 3D documentation record, Photomodeler gives good result. For Large city reconstruction; CityEngine is a good product. Agisoft Photoscan software creates much better 3D model with good texture quality and automatic processing. So this image based comparative study is useful for 3D city user community. Thus this study will provide a good roadmap for geomatics user community to create photo-realistic virtual 3D city model by using image based techniques.

Abstract:

Web-based photo albums that support organizing and viewing the users’ images are widely used. These services provide a convenient solution for storing, editing and sharing images. In many cases, the users attach geotags to the images in order to enable using them e.g. in location based applications on social networks. Our paper discusses a procedure that collects open access images from a site frequently visited by tourists. Geotagged pictures showing the image of a sight or tourist attraction are selected and processed in photogrammetric processing software that produces the 3D model of the captured object. For the particular investigation we selected three attractions in Budapest. To assess the geometrical accuracy, we used laser scanner and DSLR as well as smart phone photography to derive reference values to enable verifying the spatial model obtained from the web-album images. The investigation shows how detailed and accurate models could be derived applying photogrammetric processing software, simply by using images of the community, without visiting the site.

Abstract:

As 3D reservoir modeling is effectively the centre stage in many multi-disciplinary reservoir management efforts, the need for effective knowledge management is paramount to ensure: Inclusion of pre-existing knowledge is in the model, including absent (or controversial knowledge), reflected in uncertainties. A definition of a modeling process comprehensively covers the reservoirs issues identified while leading to fit for purpose results in a given imposed time span. Storage of knowledge generated and a modeling audit trail during the modeling process to ensure adequate and efficient model updates over time. Creation of a link between the integrated modeling process and the discipline processes that generate the basic data that underpin the model Current 3D modelling methods and tools allow for creation of models and storing model specific workflows (i.e. software related parameters and processing chains). In addition, various efforts are undertaken to store modelling best practice, which typically entails general know-how about creating models. During a specific 3D modelling project, however, a considerable body of knowledge is generated about what and what not makes the model work for a given reservoir. Such knowledge, which are essential for systematic uncertainty assessment during an existing modelling effort or subsequent modelling efforts, needs to be managed in order to retain its relevance. This extended abstract focuses on application of knowledge management in the EP industry, particularly on how process or workflow-based knowledge management approaches add value in the context of 3D modeling projects for multidisciplinary reservoir management.

Abstract:

Unmanned aerial vehicles (UAVs), which have been widely used in recent years, can acquire high-resolution images with resolutions in millimeters; such images cannot be acquired with manned aircrafts. Moreover, it has become possible to obtain a surface reconstruction of a realistic 3D model using high-overlap images and 3D modeling software such as Context capture, Pix4Dmapper, Photoscan based on computer vision technology such as structure from motion and multi-view stereo. 3D modeling software has many applications. However, most of them seem to not have obtained appropriate accuracy control in accordance with the knowledge of photogrammetry and/or computer vision. Therefore, we performed flight tests in a test field using an UAV equipped with a gimbal stabilizer and consumer grade digital camera. Our UAV is a hexacopter and can fly according to the waypoints for autonomous flight and can record flight logs. We acquired images from different altitudes such as 10 m, 20 m, and 30 m. We obtained 3D reconstruction results of orthoimages, point clouds, and textured TIN models for accuracy evaluation in some cases with different image scale conditions using 3D modeling software. Moreover, the accuracy aspect was evaluated for different units of input image—course unit and flight unit. This paper describes the fundamental accuracy evaluation for 3D modeling using UAV imagery and 3D modeling software from the viewpoint of close-range photogrammetry.

Abstract:

The traditional design method of 3D animation modelings, by which can obtain attractive and precise 3D animation modelings, is to use three-dimensional modeling software such as Maya or 3D Max to draw directly. However, this method is faced with many problems, for instance, the lack of creativity, long design circle, high production costs, etc. For the problem of the lack of creativity, the reason is that animation designers are often subject to the limitation of the existing modelings and design concepts in the design process, therefore, they can not design creative modelings which are attractive and unforgettable enough. [For the problem of long design circle and high production costs, the reason is that although the 3D animation software are powerful, to skillfully master them not only requires users to have knowledge of computer technology and aesthetics at the same time, but also need a long learning process of modeling. Moreover, it takes the designers a lot of time and energy to design, draw and complete each modeling, and this will undoubtedly extend the design circle and increase the costs to some extent. Therefore, how to quickly and automatically generate creative 3D animation modelings has become a research focus of the present computer-aided creative design.

Since Vietnam began to open up to the outside world in the 1990s, its national shipbuilding industry has witnessed great development. So far it has assumed a share of the international shipbuilding market. To build ships for foreign custumers is obviously more complicated than for dosmetic shipowners. Nowadays, the computer technology has been advancing greatly. So, to compete with foreign designs, we have also devised a strategy to develop its techniques and technology by acquiring the latest software from advanced shipbuilding countries like United States, Europe, Korea, Japan, China, … Among the special modern softwares – Plant Design Management Systems (PDMS) is a new trend in the shipbuilding industry. Indeed, the naval architects and marine engineers can design, modify, manage hull construction and outfitting their database on the 3D object with its … and their drawing travelled directly to CNC machines. All in all, we have little time to catch this new techniques of the global. This is both a challenge and an opportunity to the national shipbuilding industry.

Abstract:

This paper describes the process of developing a software tool for digital artistic exploration of 3D human figures. Previously available software for modeling mesh-based 3D human figures restricts user output based on normative assumptions about the form that a body might take, particularly in terms of gender, race, and disability status, which are reinforced by ubiquitous use of range-limited sliders mapped to singular high-level design parameters. CreatorCustom, the software prototype created during this research, is designed to foreground an exploratory approach to modeling 3D human bodies, treating the digital body as a sculptural landscape rather than a presupposed form for rote technical representation. Building on prior research into serendipity in Human-Computer Interaction and 3D modeling systems for users at various levels of proficiency, among other areas, this research comprises two qualitative studies and investigation of the impact on the first author's artistic practice. Study 1 uses interviews and practice sessions to explore the practices of six queer artists working with the body and the language, materials, and actions they use in their practice; these then informed the design of the software tool. Study 2 investigates the usability, creativity support, and bodily implications of the software when used by thirteen artists in a workshop. These studies reveal the importance of exploration and unexpectedness in artistic practice, and a desire for experimental digital approaches to the human form.

Abstract:

Vector graphics and 3D modeling have opened up a wide range of perspectives for designers to create various art objects. The use of computer graphics greatly simplified the process of sketch creating, as it provided the ability to change, add colors, and edit entire groups of objects. 3D modeling made it possible to recreate products, taking into account the smallest details in a virtual environment, compose an interior, and perform animation of various processes. The research object is the computer programs Corel Draw and 3D max and their importance for the methodology of development and creation of art objects. As a result of the study, it was found that vector graphics and 3D modeling programs not only made it easier for designers to create art objects, but also made it possible to improve the level of design by changing the usual perception. According to the authors, software products influenced the development of design, which made it possible to create any objects in a virtual environment.

Abstract:

3D space registration and visualization has become an imperative need in order to optimally reflect all complex cases of rapid urbanization of property rights and restrictions. Besides, current technological advances as well as the availability of sophisticated software packages (proprietary or open source) call for 3D modeling especially in the GIS domain. Within this context, GIS community's present demands concerning the third dimension are discussed, while a variety of 3D modeling techniques is presented, with special emphasis on procedural modeling. Procedural modeling refers to a variety of techniques for the algorithmic generation of detailed 3D models and composite facade textures from sets of rules which are called grammars. In this paper procedural modeling is employed via CityEngine software focusing on the 3D visualization of the National Technical University of Athens (NTUA) campus' three-dimensional model, rendering a higher detail on the School of Rural and Surveying Engineering (SRSE). This algorithmic modeling concept is based on the principle that all real world buildings are defined by rules, since repetitive patterns and hierarchical components describe their geometry. The detailed geometries of the model derived from the application of CGA (Computer Generated Architecture) shape grammars on selected footprints, and the process resulted in a final 3D model, optimally describing the built environment and proved to be a good practice example of 3D visualization.

Abstract:

Fisheye lenses are becoming more popular in complete image-based modelling projects of small and narrow spaces. The growing interest in fisheye lenses is confirmed by the availability of different commercial software incorporating a fisheye camera model. Such software are now able to carry out the steps of the image processing pipeline in a fully automated way, from camera calibration and orientation to dense matching, surface generation, and orthophoto production. This paper highlights the advantages (and disadvantages) of fisheye lenses when used for 3D modelling projects through different commercial software. The goal is not only a comparison of commercial software, but also an analysis of the additional issues that arise when a fisheye lens is used for 3D modelling. Results confirm that a fisheye lens is suitable for accurate metric documentation, especially when limited space is available. On the other hand, additional issues where found during the camera calibration/image orientation step as well as the texture generation and orthophoto production phases, for which particular attention is required.

Abstract:

Building Information Modeling (BIM) is a design and management methodology strongly used in the Industry of Architecture, Engineering, and Construction (AEC). It allows the creation of a 3D model through parametric modelling in a workflow that updates data, geometry and semantics using the Industry Foundation Classes (IFC) standard. The purpose of this paper is to develop and apply a BIM method for road infrastructures. The creation of the BIM 3D models was carried out using different visual programming software and BIM tools, designing the spatial and parametric representation of the roadway. This way, it has been possible to discover the advantages of using procedural modelling to design road infrastructure through software that are usually used in the mechanical and architectural field. Finally, the interoperability of the software to extract and exchange information between these BIM tools was assessed.

Abstract:

In the Bridge project, design and analysis include two main components: preliminary design and detailed design, to integrate Building Information Modeling (BIM) in the design process of the Bridge. Firstly 3D modelling of the Bridge needs to be carried out, that means. It has transferred 2D drawing into 3D models. The BIM mainly focuses on modelling analysis, detection and feedback and design. Cantilever bridge construction is a step-by-step construction of a cantilever in segments and stitching them to segments previously casted by prestressing. When the cantilever segments are added to both sides of the pier, the bending moment in Bridge is negative & increases with the addition of each segment. While key blocks are added, the Bridge is converted from cantilever form to continuous form & the negative bending moment on the pier decreases. In this project, a bridge model of span 130 m has been designed and analysed in midas civil to observe the rate of change of Bending moment, reactions and deflections at different stages of construction in construction sequence and Service conditions.

Abstract:

AbstractThe same information has different cognitive difficulty in different representation forms, especially in the field of interaction design. Thus, Scientists pay attention to the design effectiveness based on visual perception. This study focuses on two problems: 1) The relationship between textual comprehension, spatial understanding and cognitive accuracy of text information; 2) The transformation differences of cognitive elements from text information to 3D image information. First, we conduct an experiment to show the cognitive transformation difference of text elements and 3D image elements. Then, we take the design of "Logoup" 3D modeling software (This is programming driven 3D modeling software) as an example, and applies the experimental results in this study to the interface design of the software. By setting up horizontal and vertical reference planes in the real-time rendering area of the software, we can improve the cognitive efficiency and user experience of users and provide non-professional 3D modeling skill of users with an entrance to create 3D shapes.

Abstract:

ABSTRACT Introduction Patients suffering from problems related to teeth crowding and misalignment require braces for realignment and restoring of perfect teeth. This process of realignment is a long-term treatment varying from 6 to 12 months including many stages during which teeth alignments are achieved in small steps. Patients are always eager to view their futuristic teeth alignment condition at the beginning of their treatment. This requires a predictive methodology on the part of the dentist, which is achievable using software tools and finally reproducing these software-designed stages using rapid prototyping. Materials and methods Dental molds, 3D Scanner, 3D Printer, and 3D computer-aided design software, such as 3-Matic, Maestro ortho studio, 3D Orchestrate, or 3Shape ortho studio for manipulations. Results According to the quantitative analysis, average variation between the preprint and postprint is 0.32. Threedimensional (3D) printed models of these stages are within the units of 0.01 mm; hence, the rapid prototyping method supplements automation of the complete procedure of teeth alignment. Whereas, qualitative analysis of the scans after printing shows little-distorted boundaries due to which clarity has been slightly decreased but, according to the experts, this is clinically acceptable. Conclusion In this study, we provide an insight into generating different aligned stages or steps using available 3D software and further 3D printing of these stages using polylactic acid models. Clinical significance These models are expected to provide very important and tangible information related to the treatment purpose to both patients and dentists. These 3D models further provide platform for the manufacturing of customized transparent teeth aligners which are specific to the patient, better in esthetics, easy to wear, and is inexpensive than traditional teeth braces.

Abstract:

Abstract. Drones are becoming popular in spatial mapping or survey. The use of drones survey can be seen from it low flying heights (capable to create a clear images), accessible on difficult or non-friendly vehicle access areas, faster data acquisition and higher data resolution henceforth improve the quality of the survey. However, this paper focuses on the post-processing of drone images for 3D surface modeling. With the motivation of producing better 3D models, four software packages are used for comparison. Those software packages are eyesMap3D, Drone Deploy, Agisoft PhotoScan and Pix4Dmapper. The equipment used to ensure a high level of quality model is the Leica GPS1200+ stationary GPS module and the DJI Phantom 4 PRO drone. The Leica GPS1200+ stationary GPS module were used to track the exact position of tie points on the ground. Meanwhile the DJI Phantom 4 PRO drone is used as data inputs (images) for the software packages stated. In addition, the drone is used to fly over a golf course, with a challenge of homogenous surface for 3D surface modeling. Based on the output, it shows that each software packages produces slightly different outputs. This paper summarizes the outputs and discusses the key elements in each software packages. This variation might be useful for future references in 3D surface modeling that can conform in different applications requirements.

Abstract:

The 3D modeling of the vascular system could be achieved in different ways: In the venous location, the morphological modeling by MSCT venography is used to image the venous system: this morphological modeling tool accurately investigates the 3D morphology of the venous network of our patients with chronic venous disease. It is also a fine educational tool for students who learn venous anatomy, the most complex of the human body. Another kind of modeling (mathematical modeling) is used to simulate the venous functions, and virtually tests the efficacy of any proposed treatments. To image the arterial system, the aim of 3D modeling is to precisely assess and quantify the arterial morphology. The use of augmented reality before an endovascular procedure allows pre-treatment simulation, assisting in pre-operative planning as well as surgical training. In the special field of liver surgery, several 3D modeling software products are available for computer simulations and training purposes and augmented reality.

Abstract:

Periprosthetic acetabular fractures after total hip arthroplasty (THA) are mostly related to low energy trauma reduced bone quality. CT-scan is widely used to evaluate acetabular fractures, however, metal artifacts produced prosthetic implants limit the visualization of the articular surface and bone loss assessment. 3D modeling software allows us to creating tridimensional images of the bony surface, removing the metallic implants trough image segmentation. We highlight the use of 3D modeling and rapid prototyping (3D printing) for the diagnostic process of periprosthetic acetabular fracture around THA. 3D modeling software was used to improve the assessment of fracture morphology and bone quality. Moreover, the 3D images were printed in a real-life size model and used for preoperative implant templating, sizing and surgical simulation.

Abstract:

When developing a game in Unity using 3D models, it became necessary to create your own 3D models, so Unity's own capabilities were analyzed for creating 3D models. Since Unity's capabilities as a 3D modeling environment are limited, third-party software products designed to model 3D objects were considered. As a result of the analysis, the 3D blender editor was chosen for the development of objects, and therefore there was a need to study the features of importing finished objects from Blender to Unity. Unity's decision to use 3D models created in Blender is based on Unity's limited 3D modeling capabilities. Because of this, a guide was formulated, which describes what you need to pay attention to in order to prepare objects from Blender to Unity. This article provides a brief description of the professional tool for developing 3D models and game engine, which is supposed to export the resulting 3D models, including a brief historical background about them, their main features, features, thanks to which they win among other software products designed for 3D modeling and game creation, as well as information about what areas and how widely these products are used. The main errors that occur when importing ready-made objects are considered, as well as the features of preparing ready-made models from Blender to Unity are described. In addition, the reasons why it is necessary to use several software products to create a full-fledged product are considered. The description of the export process in the considered tool is presented. The step-by-step process of preparing an object for export to Blender is analyzed in detail. The order and features of preparation for exporting objects from Blender to Unity are considered on the example of preparation and export of a model of a toy bear modeled in Blender. For this purpose, a detailed analysis of the subject area was carried out, the results of which are presented in this article in the form of a step-by-step description of the process of preparing the object for export.
