How to combine the human-and-computer interaction and painting art is a hot topic in the fields of computer graphics, virtual reality, film-television advertisements and games. This paper presents an algorithm for interactive simulation of realistic sand painting based on Kinect in real-time, which consists of three sub-systems: the preprocessing system, the user interaction information capture system,...
The wireless signal needs to constantly test to discover and correct signal problem since its planning and construction. Currently, most of the existing wireless signal testing equipment are testing on the road, and there are many shortcomings. The real-time wireless signal testing and analyzing system based on websocket has realized the mobile, networked and real-time road test for the wireless signal,...
The timing of communication (e.g. deadline, response time) is an important issue in cyber-physical systems (CPS). Control Area Network (CAN) is characterized by low-cost, real-time and high reliability; and it is widely used in a kind of typical applications in CPS (e.g. lunar probe, unmanned aerial vehicle). In this paper, we characterize the mutual-effects of physical dynamics and computing process...
Dynamic water surface simulation is one of the most challenging issues in computer graphics. This paper implement an effective method for simulating dynamic water ripple effect in real-time. In the method, the water surface is constructed as a mass-spring grid, and the motion status of each mass point can be computed with Hooke's law. Instead of computing the mass points' motion in three dimensional...
Dynamic rendering large scale forest is still difficult, since it needs to create, maintain, grow and destruct tens of thousands of plant objects at runtime. This paper deals with this difficulty and presents a scene graph based scheme that allows us to model plants according to their growth stages, organ structures, and level of detail (LOD) requirements. To efficiently manipulate plant objects at...
