Ecological community is one of the most important ecological urban design types, is city's important place in public life, and also the best place to study urban ecology. However, in the construction and planning of ecological communities will inevitably involve landscape planning, human environment, road traffic, ecological planning and other issues. This article propose the planning strategies from the establishment of ecological security pattern, ecological restoration, corridor penetrate three aspects, discuss the mode of educate of the community on the ecological construction and planning.
In this paper, we proposed an X3D-based virtual good presentation method on mobile device among wireless network. In our method, we utilize the X3D technology to transmit the 3D model from the server to the mobile client in order to decrease the client’s storage. Besides, we propose an efficient interaction method for the 3D good model so that the mobile user can control these models freely. Based on these key technologies mentioned above, the framework of the system is elaborated in detail at the end of this paper.
In this paper, we proposed an improved antialiasing method for graphics hardware. We first give a detail introduction for the edge antialiasing methods which are popular now. Then, an improved edge antialiasing method is proposed. The basic idea of this method is that we employ five scanlines to scan all the sampling occurently. Thus, every three samples will be formed into a final sample and be stored into a unused storage space. Actually, this method is feasible to be implemented by hardware since it is low-cost. Experimental results show that our method can achieve good appearance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
