Light interaction considering scattering and absorbing is implemented with some simplicity physically. Dead reckoning based calculation is used during the implementation. After the 3D cloud being integrated using cellular automata clouding modeling method, experimental results show that it has realistic effect with fast rendering speed on a common PC. The method in this paper is very suitable for...
In order to change the communication circuit board status that the speed is low and transmission distance is short of control console of marine simulator designed by Institute of Nautical Science & Technology, considering the characteristic of communication in real-time between the computer and control console of marine simulator, an expanded proposal is presented and implemented. In this paper,...
A novel method for simulating large-scale, nearshore sea surface is presented. The whole simulating process can be divided into two phases: pre-computing phase and real-time computing phase. In pre-computing phase, wave parameter distribution of a simulation area is worked out using the SWAN (Simulating WAves Nearshore) model on a coarse grid. In real-time computing phase, a small height field surrounding...
Natural phenomenon simulation such as: ocean sea, spray, snow, rain etc. is a challenging topic in field of computer graphics. How to generate spray on sea? How to consider both wave spectrum and sea scale while simulating wave in visual system? How to implement the algorithm of wave generation in real-time? Based on analyzing the relationship between sea scale and wave spectrum, the wave model of...
Large high-resolution displays have been widely applied in various applications, such as entertainment, scientific visualization, high-fidelity collaborative environments, etc. A popular way to realize such displays is to tile multi-projector together to construct one large size display. In this paper, a low-cost multi- projector seamless tiled display system is constructed using commodity hardware...
