Virtual reality systems involve the integration of both hardware and software components. The hardware enables users to navigate, interact and become immersed in the virtual environment while underlying support software creates the virtual environment and integrates the hardware into a working system. Although virtual reality is widely used for product design visualisation in engineering, there exist...
Since the publication of the first FTIR multi-touch interaction system, the public attention for the field of Single Display Groupware (SDG) has been rising constantly. Lately, former SDG systems with multi-interaction capabilities like DiamondTouch, reacTable, or Microsoft Surface have been followed by promising systems, i.e. ThinSight and MightyTrace. The latter integrate their tracking technology...
Starting from the Operations Research, the methods of linear programming approach with weight to fitting variogram is proposed, which effectively guarantee the non-negative of the results of solving. The sample points are established grid index of three-dimensional space, which greatly simplify the process of neighborhood searching sample points to insertion point, and improves the speed of model...
BIM is a detailed expression about information of projects which is based on 3D digital technology and integrates all kinds of visualization digital architectural models of relevant information in construciton project. At the same time, it supplys scientific cooperation platform about "simulation and analysis" for designer, architect, engineer, developer and end user, and helps them utilize...
PC-based open architecture control systems (OAC) become the major trend in CNC control system development. This paper focuses on the development of a complete 3D simulator for an OAC system to verify a G-code file before sending it to a CNC machine to avoid risks of damaging expensive work pieces, breaking tools and fixtures or even crashing a CNC machine because of some programming error, it also...
Skyline is perfect network three-dimensional visualization software, especially in the mass data transfer and three-dimensional performance. However, Skyline has limitations in spatial analysis. ArcGIS is also excellent GIS software, especially in the data processing and spatial analysis. This paper integrates Skyline and ArcGIS and makes full use of the advantages to construct Web three-dimensional...
Visualization in scientific computing technology can be used in architecture industry to transform three-dimensional data into images, and assist architectural design, construction, decoration, etc. Its effect is very good. In this paper we first introduced the concept of scientific computing visualization, and explained its basic methods and application areas. Then we discussed its application in...
A novel 3D online simulation system for Li/MnO2 coin cell production line was presented in this paper. In order to solve the shortcomings of using traditional solid model for static simulation, the 3D visualization of the model and online simulation for Li/MnO2 coin cell production line were realized by AutoCAD/3dsmax/G-tech/PLCReader/MappingTool /ControlCenter interaction through the external software...
Modeling plant growth is a hot topic in computer graphics and agronomic communities, with the goal to understand the biological processes involved in the function and growth of plants. Several models and software tools have been developed by researchers from different areas for this aim, but due to the different goals and background of the research teams, these models have been developed in different...
Digital technology is the leading technology in 21st century; it has already penetrated into all fields, and promotes the development of many disciplines. In recent decades, visualization in scientific computing technology can be used in architectural design to transform three-dimensional data into images, and assist architectural design. Its effect is very good In our country, the research and application...
In this paper, we started from the point of digital preservation and development of large-scale cultural heritage by combining the Global Positioning System (GPS) technology, the traditional single-point measurement with high speed, high-precision three-dimensional (3D) laser scanning technology. GPS and the traditional single-point measurement are used to establish control network to local landscape...
Geological plotting is the bridge and link between three-dimensional model of deposits and the actual engineering design. Automatic plotting and file plotting of Surpac are introduced, combined with the advantages of both, complex geologic mapping process based on secondary development of Surpac is studied. Combined with the actual needs of Fankou Lead-Zinc Mine closely, on the base of creating the...
Plant is one of the fundamental elements of the urban ecological environment and landscape, and the plant landscape information visualization is an important development trend of industrial information system. The plant landscape information visualization can be used to highlight the value and effect of plant landscape from many aspects, draw the spatial framework of plant landscape and conduct spatial...
The paper presents a new methodology for displaying the user's functional demands and evaluating product design for older people. Digital design models are integrated with virtual users (digital human models) generated in Jack software and refined from 3D body scanning data. The real interaction between physical design prototypes and potential users are captured by a 3D motion capture system. The...
A menu driven software application was developed in order to visualize military battlefields in a virtual environment. Military units were drawn on real terrain data. Some animation features were also introduced. Developed system used Lanchester combat model which was developed for evaluating which of the two forces will be victorious after the battle and how the system will reveal the fog of war.
Architects conceive buildings as three dimensional forms, often developing their designs using 3D CAD [computer aided design] or visualization software. Yet their designs are usually presented to each other and to their clients as two dimensional artifacts: such as images or movies created from their CAD models. In computing, interactive three dimensional worlds are ubiquitous, in particular in the...
The virtual environmental planning systems project (VEPs) proposed an alternative approach to planning consultation by allowing people to view and leave comments about planning developments using 3D visualization software in a Web browser, within the context of an existing landscape or cityscape.The software developed by VEPs allows users to freely explore and interact with 3D models and make comments...
Computational fluid dynamics has become increasingly important for performance evaluation in the product development process. Computer visualization provides an efficient way to assess the performance of a product. The sonification feedback of CAD system analysis, in addition to the visual interface, can increase the amount of information the user receives, reduce the load of visual channel, and provide...
The disposal, modeling and visualization of 3D data are very important in the construction of digital earth. Now, one can get fine 3D model with software such as 3DMax and so on. But the 3D system is only perfect in visualization without any function of spatial analysis. The predominant software of GIS, for example, ArcGIS, or IMAGIS, provides ideal function of spatial analysis. One also can establish...
This paper describes an immersive visualization method for post-process of ANSYS software. The mechanism of static color fringe contour and animation of the post-process of ANSYS were researched. The stereoscopic display based on VRML files and AVI files were developed.
