Abstract: Using VRML virtual reality modeling language standard steel structure CAD graphics switch into a text file. Making the complex 3D graphics information expressed in VRML environment. Make CAD graphics and VRML file according to the respective standards can use inverse. Drawings transformed into each other to create a practical and effective method.

Abstract: This article discusses the problems existing in power system graphics software, and analyze wxWidgetss characteristics like cross-platform, local perception, face to objects and other features. The validation based on the wxWidgets development can make up for the graphics software shortcomings, providing new ideas for the development of future coal mine power system graphics software.

Abstract: In computer graphic, conventional method often uses the fixed graphics in single color to introduce the design of fractal tree graphics, which makes students feel difficult to understand. In order to solve this problem, in this paper a new environment of fractal tree graphics base on E-learning is proposed, development of which is also introduced in detail. In this learning environment, the iterated depth of fractal tree graphics, and the changing angle of branch can be increased and decreased. In increasing process, the fractal limitation or fixed point can be seen clearly. In this new learning environment, students can easily grasp the fractal graphics definition and the programming procedure of fractal graphics, and understand the generation procedure and structure of fractal tree graphics. Therefore, it can arouse the students interests and attracts their attentions in the course of learning.

Abstract: Traditionally, the computer method of delineation requires to establish ore block model. The block-by-section scanning operation is slow, which does not meet the large amount of data calculation., In this paper, we use the ore body in the modeling of the surface model in order to overcome the above problem. This model uses modeling method that reproduces a traditional hand-paintedtechnique, describe the spatial distribution of ore bodies through a series of plan view or profile of the ore body boundary polygon for wireframe modeling, i.e., the frame modeling method. For reading the plan view or profile of the ore body, the graphics and fractal theory are needed in the work to achieve the extraction of vector graphics map elements. After completing the extraction of ore, the wireframe modeling of the ore bodies can be established by using wireframe modeling method. Finally the wireframe model is filled by using the OpenGL technology and the surface model orebody is generated.

Abstract: According to the structure characteristic of the fixture design, the architecture of graphics library of fixture element is established. Based on the technologies of network, library, .NET and the developing mechanism of AutoCAD/MDT, the implemented strategy of the system of graphics library of the fixture element is presented. The remote sharing of the fixture resource information is realized. The system provides process engineer of the fixture design with assistant tools.

Abstract: Quadric surface is an important part of complex object and free form object, showing its graphics is hot research of computer graphics and 3D data visualization. Researching quadric and deducing the process of its classification. Taking three 3D graphics commands contour3,ezmesh and ezsurf as main line, it is analyzed that 3D drawing function of Matlab7.It comes true that programming is to draw 3D graphics of all kinds of quadric, and it was compared that various graphics results, it can provide reference for computer mapping of any other surface objects.

Abstract: With the development of times, industry has been making great progress, which varies from primitive manual labor to machines in the age of steam. Then, machines and factories have taken the place of more and more manual labors with the development of mechanical design and relative theory. However, it still fails to reach the stage of full automation. Owing to the birth of computer and development of artificial intelligence, the robot factory is no longer a fresh topic. Undoubtedly, those are linked with graphic and computer’s development. There must be a more advanced theory and technology coming into being as graphic & image reach a higher stage. Then, it was named as the virtual realism technology. This new technology has been widely applied to various fields, such as, automatic production line, air quality automatic detector, war-simulating in army, “simulating space environment” on the earth, virtual laboratories building in the education and etc. Now, here are two basic concepts involved in the long-term development: graphics and image.
