Three-dimensional (3D) modeling has become an invaluable tool for operative planning in the continually evolving complex field of adult congenital heart surgery. We present a case of an Intra-atrial conduit leak after multiple repairs of common atrium and criss-cross morphology. 3D modeling was critical in preoperative evaluation and operative planning for complicated intracardiac anatomy after an uncommon initial approach to preserve a biventricular circulation. In the setting of complex or rare congenital cardiac anomalies, advanced imaging and 3D modeling are helpful with preoperative planning.

The method of three-dimensional model in the system of computer modeling MathCad and Autodesk 3ds Max by categories of total soil pollution is developed. A visualization block and an analytical block have been developed which are based on calculated mathematical models for analyzing and evaluating the environmental situation, risks, and environmental safety of the territory. Three-dimensional models of relief mapping of the Pekhorka river fl oodplain are constructed by integrating them with the help of a programming environment and optimized 3D modeling programs. Three-dimensional models with total soil contamination for water body sections are constructed. On the example of some sections of the catchment area of the Pekhorka river in the Balashikha region, models with soil contamination by the total ZC indicator were created. The development of 3D modeling techniques allows you to create predictive scenarios more accurately with a high degree of detail, as well as quickly approach the solution of environmental problems. Optimization of three-dimensional modeling in the fi eld of problems related to the catchment area contributes to the further operational solution of problems of rational land use and improvement of the environmental situation.

This work deals with three-dimensional (3D) modeling of container cranes including the hoisting cable length commands. The proposed models allow to effectively study the 3D motion caused by the eccentricity of initial conditions or loading conditions such as those induced by wind. The container is modeled as a 3D rigid body while the hoisting cables are treated either as inextensible trusses or as linearly elastic straight, taut cables. The 3D model with inextensible cables is shown to coalesce into existing two-dimensional models under the relevant planarity constraints. Details about the treatment of the internal inextensibility constraints are discussed. Time-marching simulations are carried out to show representative 2D and 3D responses to initial conditions and commanded motion of the trolley. The main differences between the constrained model and that with the elasticity of the cables are highlighted in the framework of a few significant design scenarios.

This paper mainly studies modeling and recognition of 3D English words’ images. With the development of secondary modeling, segmentation and recognition theories and the application of evolution computation in 3D modeling and recognition, this paper analyzes the issues of parameter fitting in the 3D model, multi-object scene segmentation and parts recognition aiming at the 3D data features in the English words. The 3D model is used as the primitives part to model and segment the scenes and the group parallel evolution and the relationship matching theories are introduced into the 3D modeling and recognition to deeply identify the rare English words’ images. The paper searches for a practical and efficient three-dimensional modeling and identification scheme.

Abstract 3D modeling technology is an important branch of interdisciplinary fields such as computer graphics, intelligent information processing, computer vision, and artificial intelligence. Through computer digitization, collecting three-dimensional data information of the target object, and then processing and simulation reproduction through computer technology, plays an important role in logistics engineering (LE). The purpose of this paper is the simulation research of LE based on computer three-dimensional modeling technology. This paper takes LE as the research object, firstly elaborates the functional and non-functional requirements of the system separately, and establishes an intelligent logistics system. This paper uses Flexsim simulation software to establish a logistics distribution simulation model. Based on the data collected in the survey, the model is parameterized. Through the data output from the simulation, the simulation data of the original logistics system and the logistics system designed in this paper are compared and analyzed. The simulation output data shows that the total number of products transported in and out of the warehouse of the original system’s 6 transport planes is 15,559, and the total number of products transported in and out of the warehouse of the 6 transport planes in the logistics system proposed in this paper is 17,144 pieces. It can be seen that this system has strong transportation efficiency in LE.

History Of

This article shows the geometric modeling and virtual reconstruction of the optical telegraph by Agustín de Betancourt and Abraham Louis Breguet developed at the end of the 18th century. Autodesk Inventor Professional software has been used to obtain the three-dimensional (3D) model of this historical invention and its geometric documentation. The material for the research is available on the website of the Betancourt Project of the Canary Orotava Foundation for the History of Science. Thanks to the three-dimensional modeling performed, it has been possible to explain in detail both its operation and the assembly system of this invention in a coherent way. After carrying out its 3D modeling and functional analysis, it was discovered that the transmissions in the telegraph were not performed by hemp ropes but rather by metal chains with flat links, considerably reducing possible error. Similarly, it has also been found that the use of the gimbal joint facilitated the adaptability of the invention to geographical areas where there was a physical impediment to the alignment of telegraph stations. In addition, it was not now necessary for the telescope frames to be located parallel to the mast frame (frame of the indicator arrow) and therefore they could work in different planes.

Background: Three-dimensional (3D) printing is a computer-directed process leading to the layered synthesis of scaled models. The popularity and availability of the technique has exponentially increased over the last decade, and as such is seeing a greater number of medical and surgical applications. Methods: We report 3 cases involving the use of 3D printing as an aid to operative planning in the revision of wrist surgery. Results: All patients underwent successful operative interventions with a £34 average cost of model creation. Conclusions: A growing number of reports are emerging in reconstructive surgical specialities including maxillofacial, orthopedic, and plastic surgery; from our experience, we advocate the economically viable use of 3D printing for preoperative templating.

The article discusses the design skills assessment method, which was developed and used to teach basics of three-dimensional modeling. This method is necessary because the creation of a virtual 3D model usually does not include the design phase as a separate phase with own specifications and design documentation and all design activities are performed in mind without any preliminary sketches. The offered method allows assessing the quality of the student's mental design operations based on the analysis of the 3D modeling process tracking. The student's activity in the 3D modeling environment was captured using special software. The obtained data allow to identify the essential parameters of the students' actions (correctness, optimality, etc.), which were used to quantify their design skills. The construct validity of the proposed method and its statistical significance of the assessment were confirmed.
