This article provides a detailed account of the process of scanning, post-processing and further manipulation of three-dimensional models obtained with structured light scanners. Purpose. The purpose of the study is determined by the need for national archaeologists to learn the methods of three-dimensional modeling for the implementation of scientific research corresponding to international standards. Unfortunately, this direction in national archaeology began to develop in a relatively recent time and there is a lag in the application of three-dimensional modeling of national archaeology compared to the world level. Results. Any archaeological, experimental or ethnographic artifact can be used for three-dimensional scanning. To perform post-processing of three-dimensional models it is necessary to carry out primary scanning of an artifact by one of the existing algorithms. The algorithm for creating models, their positioning, simplification, saving in various formats and export is described. The main sequence of 3D models post-processing includes: processing of groups of scanned projections (their cleaning and alignment), creation of artifact model and processing/rectification of the resulting model using special software. Conclusion. As a result of correct implementation of the algorithm, the researcher receives a scaled model completely corresponding to the original artifact. Obtaining a scalable, texture-free three-dimensional model of the artifact, which fully corresponds to the original and exceeds a photograph in the quality of detail transfer, allows a scientist to conduct precise metric measurements and any procedures of non-invasive manipulation of the models. The ability to access a database of three-dimensional models of archaeological collections greatly simplifies the work of archaeologists, especially in situations when country borders are closed.

This paper provides a scheme to construct three dimensional (3D) model fast using laser scanning data. In the approach, firstly, laser point cloud are scanned from different scan positions and the point cloud coming from neighbor scan stations are spliced automatically to combine a uniform point cloud model, and then feature lines are extracted through the point cloud, and the framework of the building are extracted to generate 3D models. At last, a conclusion can be drawn that 3D visualization model can be generated quickly using 3D laser scanning technology. The experiment result shows that it will bring the application model and technical advantage which traditional mapping way can not have.

Three-dimensional modeling of geological bodies is a useful tool for multiple applications. Such tasks are usually accomplished starting from field-collected data, which typically suffer from intrinsic limitations such as accessibility constraints and punctuality of data collected. In this work, we explore the reliability of photo-geological analyses starting from aerial photo-interpretation in providing data useful to build up 3D geological models, and validate them using exploration wells data in a lignite rich area in Umbria, central Italy. The procedure that produces 3D models from photo-geological data is a three-step open source GIS procedure developed using python in GRASS GIS environment and GNU-Linux OS. We maintain that this procedure can have potential broad applications in Earth Sciences, including geological and structural analyses, up to the preliminary evaluation of potential reservoirs.

This article demonstrates the possibility of a graphical program Kompas ASCON in the sphere of three-dimensional modeling of engineering and building objects. The created three-dimensional model of the training class for employees of JSC "Russian Railways" to study safety rules can have a real embodiment – all components are built according to catalogs and statements. In the course of work on this project various tools of the program are mastered: models of the room of a class of furniture are created. The basic operations of three-dimensional modeling and methods of creating assembly units are studied. All components of the class are paired. The resulting project has a high visibility and can be used as a presentation as a company that performs class projects, and the customer.

In this study, the approaches and research methods have been proposed based on the analysis of challenges in modeling, establishing a three-dimensional model of geological engineering conditions of the Hanoi area. The three-dimensional model of the Hanoi area was composed of 21 geological engineering units as a stacked structure, with accuracy and reliability were verified by statistical evaluation. Based on the integration of engineering geological attributes, the model has contributed for reconstruction of the geospatial engineering geological structure of the study area as comprehensive, continuously, and high resolution.

A three-dimensional model of two columns covering hydraulic support was created by Pro/E software. The model was imported into ABAQUS software for finite element analysis. The stresss distribution of the hydraulic support in the conditions of the top beam partial load and the base reversed was got. The result was a reference in the design and structural optimization of the hydraulic support.

OpenGL is independent of the window system, and did not provide the function to draw complex three-dimensional model, so it is difficult to properly control OpenGL and create complex model .This paper will achieve to build complex three-dimensional model efficiently and take good effect in practice with combining OpenGL and 3Dmax or with the help of functions of VC++ to develop based on applying window frame of Windows powerfully.
