This paper introduces the method of 3D modeling and visualization of ArcGIS combined with SketchUp, and describes the pipeline modeling process in SketchUp. And a drain-pipes network 3D GIS system is established with the actual drain-pipes data, which can fulfill the functions of three-dimensional display of drain-pipes network, pipeline locating, roaming and other functions.

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.

This chapter outlines the advantages of digital epigraphy in the context of the original monuments. It analyzes the perception of epigraphic publication of monuments, taking into account new technologies. 3DVR models can be created using architectural drawings and measurements (CAD and 3D modeling), 3D scanning, and Structure for Motion (SfM). These systems present different advantages and challenges, which are discussed. Current options for publication include VSim, 3D GIS, and Unity 3D platforms. The issues of peer review of publications and long-term preservation of data are addressed. The chapter concludes with a consideration of the issue of potentially misleading impressions given by 3DVR representations.

In order to improve the accuracy of dynamic detection of wind field in the three-dimensional display space, system software is carried out on the actual scene and corresponding airborne radar observation information data, and the particle swarm algorithm fuzzy logic algorithm is introduced into the wind field dynamic simulation process in three-dimensional display space, to analyze the error of the filtering result in detail, to process the hurricane Lily Doppler radar measurement data with the optimal adaptive filtering according to the error data. The three-dimensional wind field synchronous measurement data obtained by filtering was compared with three-dimensional wind field synchronous measurement data of the GPS dropsonde in this experiment, the sea surface wind field measurement data of the multi-band microwave radiometer, and the wind field data at aircraft altitude.

Accidental or malicious releases in the atmosphere are more likely to occur in built-up areas, where flow and dispersion are complex. The EMERGENCIES project aims to demonstrate the operational feasibility of three-dimensional simulation as a support tool for emergency teams and first responders. The simulation domain covers a gigantic urban area around Paris, France, and uses high-resolution metric grids. It relies on the PMSS modeling system to model the flow and dispersion over this gigantic domain and on the Code_Saturne model to simulate both the close vicinity and the inside of several buildings of interest. The accelerated time is achieved through the parallel algorithms of the models. Calculations rely on a two-step approach: the flow is computed in advance using meteorological forecasts, and then on-demand release scenarios are performed. Results obtained with actual meteorological mesoscale data and realistic releases occurring both inside and outside of buildings are presented and discussed. They prove the feasibility of operational use by emergency teams in cases of atmospheric release of hazardous materials.

Abstract Owing to the existence of the cone angle, the size of a conical counter-rotating twin screw continuously changes along the axis, so it is not easy to model using SolidWorks. In this study, the parametric design of the modeling process is completed based on the Visual Basic language and a program-driven method. Finally, the SolidWorks program plug-in and user interface are developed to complete the automatic generation of the three-dimensional model of a conical counter-rotating twin screw.
