A new adaptive mesh simplification method based on vertex clustering is presented in this paper, which can preserve the model topology and subtle geometric features better than traditional vertex-clustering methods. Guided by the normal vectors corresponding to all vertices, the proposed method adopts a binary tree structure to split the bounding box of the inputting model adaptively. This subdivision...
Naxi pictograph is a Tibeto-Burman, and it is the only pictograph in use nowadays. The traditional national minority language network information processing downloads through the ActiveX technology the typeface as the card the client side, after the installment only then can browse normally contains the national minority language homepage, this mode efficiency low also takes the massive networks resource...
Computer science and technology are constantly changing, which results in the changing interface between computers and people. The integration of space science and computer science make space scientists gain some form of higher-level insight into massive data sets. So it is crucial to develop technology that supports presenting space data effectively. Scientific visualizationpsilas role in presenting...
Temperature is one of the most prevalent and important parameters in industry production process. Moreover, it is very important to realize intelligentized management of temperature detection for development of industry. In order to realize this target it researches and designs a voice and graph display system on temperature detection. It sends data to computers, saves data to database, reads current...
A refinement of Petri nets is a transformation by replacing a simple entity of a system with its functional and operational details. In general, the refined system may become incorrect even if the original system is correct because some of its original properties may have been lost or some undesired properties may have been created. For systems specified in ordinary Petri nets, this paper proposes...
To provide with an effective method for computer generated images with artistic appearances from 2D images motivates our work in this paper. We mainly propose the method for generating the artistic appearances based on the deviation mapping technique. As the preprocessing of the deviation mapping, the texture synthesis can be fulfilled to produce the background image with the same size of the foreground...
A water distribution network model which was based on virtual reality was constructed and the state-of-art was simulated in a 3D scene. It works with a clear sense. The water network engineering database was built firstly in this paper to keep the precision of the 3D model. The water network model was constructed after the 3D models of the valves and pipes were made. The model was driven by the Vega...
