Prism Geometry: Simple and Efficient 3-D Spatial Model
نویسندگان
چکیده
With the recent increase of demands for 3D information, we need a robust data model of 3D spatial objects to meet the requirements from diverse applications. For this reason, several studies have been done out by ISO/TC211 and OGC, among which the data model of ISO 19107[2] and the data model for KML[6] are the most important ones. The data model of ISO 19107 provides a strong expressive power of 3D spatial information with a sophisticated model for full 3D solid object. And GML[4] is based on the spatial data model of ISO 19107. However this data model has a serious drawback that the size of data in GML is large and the implementation of ISO 19107 is difficult and heavy, due to the complicated structure of this data model.

SOME POINTS ON CASIMIR FORCES
Casimir forces of massive ferrnionic Dirac fields are calculated for parallel plates geometry in spatial space with dimension d and imposing bag model boundary conditions. It is shown that in the range of ma>>l where m is mass of fields quanta and a is the separation distance of the plates, it is equal to massive bosonic fields Casimir force for each degree of freedom. We argue this equalit...
متن کاملQuadtree and Octree Grid Generation
Engineering analysis often involves the accurate numerical solution of boundary value problems in discrete form. Hierarchical quadtree (or octree) grid generation offers an efficient method for the spatial discretisation of arbitrary-shaped two- (or three-) dimensional domains. It consists of recursive algebraic splitting of sub-domains into quadrants (or cubes), leading to an ordered hierarchi...
متن کاملRepresentation of a 3-d City Model in Spatial Object-relational Databases
Three-dimensional city models become more and more important in many GIS applications. Examples are, apart from simple visualization, city and land use planning as well as telecommunication planning and disaster management. Currently, there are no 3-D GIS available, which are suitable for these applications. For managing large spatial data sets in an efficient and sustainable way, spatial datab...
متن کاملA Novel Multimode Mobile Robot with Adaptable Wheel Geometry for Maneuverability Improvement
In this paper, an innovative mobile platform is presented which is equipped by three new wheels. The core of the new idea is to establish a new design of rigid circular structure which can be implemented as a wheel by variable radius. The structure of wheel includes a circular pattern of a simple two-link mechanism assembled to obtain a wheel shape. Each wheel has two degrees of freedom. The fi...
متن کاملThe Study of Determinants of Rent Housing in Ilam City Based on Hedonic Spatial Econometrics
Abstract: Housing unit is heterogeneous and multidimensional commodity; therefore, to determine effective factors on rent, hedonic pricing model is used. To explain the factors, four properties are used for housing, which are physical variables of residential units, access variables, environmental variables (neighborhood), and economic and social characteristics. The variables related to the sp...
