In order to study the evolution and metallogenic regularity of MVT lead-zinc deposits in western portion of Hunan province (China), two sets of three-dimensional model are established by Minexplorer software: 3D model in typical deposit and 3Dmodel on regional scale. On the basis of synthetic analyses of two sets of models, the further prospecting should be focused on the north part of ore-bearing layer along the Huayuan-Zhangjiajie fault belt. It is effective to observe occurrence and distribution characteristics from the 3D geological model, and to provide the basis for further exploration prospecting of the concealed deposits.

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.

In the process of engineering and geological surveys, three-dimensional engineering-geological modeling makes it possible to perform a comprehensive assessment of the state of the territory for making sound-design decisions on the placement of construction sites and their structures. Secondly, a logical conclusion of a detailed study of engineering-geological and geotechnical conditions, which is implemented to use three-dimensional modeling, is a well-grounded design with a reasonable margin of safety, which causes a reduction in the total cost of the erected or reconstructed structure. Thirdly, in comparison with traditional engineering-geological two-dimensional models (cuts, maps, etc.), three-dimensional models give more information. This is especially important, when we think about the scale of the hydraulic structures. According to archival materials, it can be noted that there are many spatial geological heterogeneities in this territory, and the engineering-geological conditions turned out to be complex. Taking into account the advantages of three-dimensional modeling, the creation of a three-dimensional model of a dispersed soil massif is an actual task for solving complex engineering-geological problems. The article analyzes a three-dimensional engineering-geological model of the soil massif under a hydrotechnical building in the Moscow region, and then calculates its stress-strain state and the coefficient of stability of the sides of the ditch.

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,
