Different from the 4-points interpolation subdivision curve scheme, the proposed subdivision curve scheme in this paper is based on cube Bezier curve. More importantly, the normal vectors are used to generate a circle from a triangle with the advantages of only 3 vertices and 3 edges. Furthermore, we make new contributions in the subdivision surface scheme compared to the existing methods. It has...
Simulation experiment, exploiting software and hardware of the computer to generate a simulation of an environment, is a more popular technology in education. This paper discusses the combination with Virtual C++ and 3dsmax to achieve physics simulation experiments, which can apply the images created by 3dsmax to the physical model of the experiment and use Visual C++ to make the demonstrating process...
In order to describe traffic operation characteristics of bi-directional pedestrian flow in urban pedestrian walkways and work for walking safe, authors proposed an improved cellular automaton bi-directional pedestrian flow model. This model takes into account many basic pedestrian behaviors, forward move, side stepping, position exchange, lateral-move and step back, and, using MOORE Neighborhood...
An algorithm of early fire image detection and identification based on discrete fractal Brownian incremental random field model (DFBIR) is proposed in this paper. The flame color brightness and motion clues are chosen as the imprint of the fire image. At first, the suspicious fire region is detected by the flame color model. And the differential model is used to analyze if the suspicious fire region...
The modeling of virtual logistics is very difficult due to its intuitional complexion. The agent technology, which is developed from the artificial intelligence, provides the simulation of complex systems with new methodology and idea. In this paper, the reconstruction model of virtual logistics is introduced based on multi-agent technology. And also, the functions of agents are defined, the negotiation...
