AbstractOrbitocranial reconstruction objectives include creation of a solid barrier between intracranial contents and the environment allowing restoration of physiologic homeostasis and restoration of aesthetic craniofacial contours. Historically, bone grafts have been used for reconstruction but were fraught with unpredictable resorption and imperfect contouring given the complex anatomy of the orbitofrontal bones. With advances in three-dimensional modeling technology, alloplastic custom implants in orbital and frontal bone reconstruction have allowed for rapid fixation reducing surgical times and improved cosmesis.

Virtual reality scenes three-dimensional modeling usually is constructed on the basis of learning with virtual data, and learning behavior is too dependent on virtual data.It is difficult to quickly and accurately reflect characteristics of 3D modeling in virtual reality, and learning complexity is higher. In this paper, a method of virtual reality scenes three-dimensional modeling based on semantic was presented on the basis of analysis of the virtual scenes modeling methods. The modeling system architecture using the method is divided into physical model libraries, three-dimensional model semantic knowledge base, semantic-based visual modeling and scene graph automatically generation modules. The experimental results show that the detection performance is better than the results of the three-dimensional modeling based on virtual data, and the system increases flexibility and usability of the three-dimensional modeling,

Three-dimensional model of the parts of the extrusion extruder for leisure food is created as an illustrator, which could be adopted up to form an assemble facility to the whole set of the machine conveniently by a software of SolidWorks in the paper.Some key specific modeling procedures are proved to show the advantages of Solidworks overweigh AutoCAD in three-dimensional modeling technology. The method put an adaptable way to short the whole lifetime of industrial product design.

The article is devoted to the issues of using three-dimensional modeling as a way of information and technical support of forensic registration. It is stated that none of the modern researches focuses on the use of three- dimensional modeling technology of information and technical support of forensic registration. An assessment of the technological capabilities of modern three-dimensional scanners (3D-scanners), which are used (or can be used) in the information and technical support of forensic registration. The technological possibilities of three-dimensional modeling are analyzed, in particular in the construction of three-dimensional models of the scene, the creation of virtual rooms for educational purposes, forensic examinations, etc. Emphasis is placed on the fact that in criminology, three-dimensional (3D) modeling is carried out according to the rules of solid modeling (in which the key is to reproduce the physical properties of three-dimensional modeling objects). It is the physical properties of forensic registration objects, as a rule, that are the key information, the fixation of which is carried out within the framework of forensic registration. It is determined that the prospects of using three-dimensional (3D) modeling during forensic registration are to ensure the possibility of creating objects of accounting using additive technologies (ie three-dimensional printing (3D- printing)). The position is expressed that the technologies of three-dimensional (3D) modeling can be applied, first of all, in: trasological accounting; ballistic accounting; cold steel accounting; registration of persons on the basis of appearance; accounting of materials, substances and products. Therefore, with 3D modeling, it is possible to reproduce a certain three-dimensional object if it has been properly scanned. The described technologies create opportunities not only to quickly create exact copies or duplicates of evidence or other objects that are placed in forensic accounting, and use them for other research or for use as objects of orientation during operational or investigative actions.
