Implementation of Elementary Geometric Database Operations for a 3d-gis
We report on a preliminary study carried out for the development of a 3D-GIS, which is supposed to manage geoscientific data of the Lower Rhine Embayment. The implementation of geometric 3D-operations is fundamental for 3D-GIS. Here we present the realization of an extensible geometric library implemented within an object oriented prototype database kernel system. The spatial representation use...
متن کامل3D User Interfaces for General-Purpose 3D Animation
Modern 3D animation systems allow a rapidly growing community to create and animate increasingly sophisticated worlds. Despite the inherent three-dimensionality of these tasks, the user interfaces of such systems are still predominantly two-dimensional, using 2D input devices and techniques which severely limit the range of tasks that can be accomplished interactively. In particular, these limi...
متن کاملDeveloping Three-dimensional (3d) Topological Model for 3d Gis
3D spatial data modeling is one of the key research problems in 3D GIS. More and more applications depend on these 3D spatial data. Mostly, these data are stored in Geo-DBMSs. However, recent Geo-DBMSs do not support 3D primitives modeling, it only able to describe a single-attribute of the third-dimension, i.e. modeling 2.5D datasets that used 2D primitives (plus a single z-coordinate) such as...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
3D Navigation for 3D-GIS - Initial Requirements
The needs for three-dimensional (3D) visualization and navigation within 3D-GIS environment are growing and expanding rapidly in a variety of fields. In a steady shift from traditional two-dimensional (2D) GIS toward 3D-GIS, a great amount of accurate 3D data sets (e.g. city models) have become necessary to be produced in a short period of time and provided widely on the market. This requires a...
