Forest evolution simulation and visualization are challenging tasks in terms of complex interactions at various time and space scales. In this paper we present a forest evolution simulator system, based on individual-based, spatially explicit forest gap model, incorporating with fine-scale process of neighbor competition and understory recruitment. The forest evolution for each growth cycle is visualized...
Simulation of variable spatiotemporal-scale forest growth is a trend in virtual forest simulation field. Most existing virtual forest simulation systems have relatively fixed structure and weak reconstruction capability. Besides, there is much duplication of work between different-granularity forest simulation systems. Therefore, this paper presents component-based forest simulation system architecture...
A system the final goal of which is to design feelings of fabrics has been developed. For this purpose, cloth was modeled based on thread model and geometrical arrangement of threads of cloth. A simulation system was constructed with the cloth model. In the system, a lot of calculating time is required when wide range of cloth is treated. The system was accelerated with a Cell/B.E. processor. By SIMD...
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
The flow simulation in virtual reality can make invisible flow phenomena existing in nature visible in three-dimension scene. It can aid researchers to observe, comprehend and analyze the natural phenomena. The architecture based-VR presented in this paper has been designed to make flow simulation easy and universal. A spatial class hierarchy is proposed to extract the abstract objects from flow phenomena...
