Geological applications often need displaying of the shape, structure and spatial distribution of underground rock through exploring the geological survey database. In this paper, we present an approach for interactive modeling and visualization of three-dimensional (3D) Geological Bodies. A Hybrid 3D data model based on multi-DEMs and tri-prism volume is introduced for depicting the 3D Geological...
Orebody modeling is one of the most important contents of the mine visualization. Orebody usually has complex shape,and its spatial distribution is very irregular. In the modeling process, model editing is the key step in visualization. From the perspective of software development, this paper discusses the method and progress related with the design and implementation of a 3-D orebody wire-frame modeling...
When operating traffic route guidance systems (TRGS) and providing road users information about traffic state through VMS (variable message signs) systems, most operators and engineers, with their experience and using aggregate statistic data, suppose that all drivers share the same standard for understanding and assessing traffic state. However, each receiver actually has his/her own standard to...
