The advent of 3D printers has been embraced globally within few years of its emergence. The surge in the acceptability of rapid manufacturing RM technology can be attributed to the depletion and cost of natural resources, waste reduction and sustainability criterion of manufactured parts. This rapidly evolving 3D printing technologies is predicted to grow exponentially especially for the manufa...

ReservoirBench is an interactive workbench for educational geological science and engineering tasks. It is designed to facilitate education of novice audiences to teach them basic concepts of reservoir modeling and simulation workflow. Traditional training using lectures and software practice can lead to information overload, and retainability is questionable. As an alternative, we propose a ph...

This work presents the application of a geostatistical-based modeling approach for building up electrical properties acquired from a geophysical electrical tomography survey deployed for the purpose of porphyry Cu exploration at the Takht-e-Gonbad deposit, in the central domain of Iran. Electrical data were inverted in 2D along several profiles across the main favorable zones of Cu-bearing mine...

The complex organic forms we find in nature are typically difficult to geometrically model using traditional 3D modelling tools. This is because they often have complex surfaces and large number of components, which are tedious to create when manipulating the geometric model directly. One approach to this problem is to generate the geometry through simulation. The Simplicial Developmental Syste...

Several existing procedural modeling systems are able to generate large 3D models of cities. However, none of these systems can automatically create 3D models of freeways and freeway interchanges, even though these are important features in 3D urban landscape. We have implemented a system that automatically creates 3D models of road surfaces, bridges, tunnels, freeways, and freeway interchanges...

Advances in computer technologies make it possible to create three-dimensional and interactive geological information systems. A Constrained Delaunay Triangulation (CDT) algorithm which considered the line segments of the geological polygons as constrained edges and all vertices of the digital elevation model (DEM) inside the polygons was applied to construct CDTs. Triangles outside the polygon...

1. Abstract We propose a method to interactively modify contacts between surfaces in a 3D boundaryrepresentation geological model. The modification is based on a hierarchy between a slip surface (a surface that other surfaces can slide along, which in geology could include faults, erosion surfaces, salt tops) and a secondary, deformable surface (e.g. horizon, older fault). The border of the def...

The spatial interpolation of property fields in 3D, such as the temperature, salinity, and organic content of ocean water, is an active area of research in the applied geosciences. Conventional interpolation methods have not adequately addressed anisotropy in these data. Thus, in our research we considered two interpolation methods based on a triangular prism volume element, as a triangular pri...

Today's geo-information systems are closed systems mainly supporting geographic tasks in 2D space. In new spatial application areas such as environmental research, geology, city planning or telecommunications, however, a database and processing support for 3D/4D objects is required. Thus the development of object-oriented 3D/4D modeling and data handling components for geoinformation systems is...
