The documentation of cultural heritage in 3D using non-contact laser scanning, and the wide variety of applications that the resulting data can be used for, are well documented. Increasingly, the 3D data is being used by artists, both in their work, and as a tool to realise their ideas. During recent regeneration, Sheffield City Council awarded the remit to design sculptural planters for Tudor ...

Capturing and modelling 3D information of the built environment is very challenging. A number of techniques and technologies are now in use such as EDM, GPS, photogrammetric applications, and building surveying applications. However, use of these technologies has not been practical and efficient with regard to time, cost and accuracy. A multi-disciplinary knowledge base, created from studies an...

We present BlobMaker, a program for modelling surfaces which uses variational implicit surfaces as a geometrical representation to edit free form shapes. Our approach implements new modelling operations to support stroke (pen-based) input. To this end, we have built a complete modeller application. Users can create and manipulate shapes by sketching on a perspective or parallel view. The main o...

Developing a three-dimensional (3D) data model for Geographic Information Systems (GIS) is an essential and complex issue. 3D modelling in GIS is becoming ever more important for the development of cyber cities and digital earth, which have recently become feasible. A competent 3D model forms an efficient foundation for 3D visualization, query and spatial analysis. As a development of the exist...

This paper explains the different interactions between the Artificial Intelligence (AI) techniques and 3D modelling, not only the wide-used application of AI in order to the implementation of 3D environments, but the less explored use of 3D models in order to take advantage from AI techniques. The authors will be especially interested in real Engineering applications, but the techniques present...

There is growing interest in adopting three-dimensional virtual environments within spatial design courses to use digital modelling techniques to support students’ learning. One pedagogical issue that has received little attention so far is the question of how 3D virtual environments can be used to implement assessment techniques that support students’ learning of spatial design expertise. This...

This paper presents a new concept for 3D coding of freeform surfaces. The proposed coding technique uses the surface signature representation scheme [1]. This representation scheme captures the 3-D curvature information of any free-form surface and encodes it into a 2-D image corresponding to a certain point on the surface. This image is unique for this point and is independent of the object tr...

In this paper, 3D Finite Element Method (FEM)-based numerical modelling of precision hard turning has been studied to investigate the effects of chamfered edge geometry on tool forces, temperatures and stresses in machining of AISI 52100 steel using low-grade Polycrystalline Cubic Boron Nitrite (PCBN) inserts. An Arbitrary Lagrangian Eulerian (ALE)-based numerical modelling is employed for 3D p...

Building 3D models is important in many applications, ranging from virtual visits of historical buildings, game and entertainment, to risk analysis in partially collapsed buildings. This task is performed at different scales: city, buildings, indoor environments, objects and using different sensors: cameras, 2D and 3D laser, etc. Moreover, different map representation have been considered: metr...

Three-dimensional mapping has extensively developed in the last decade; geological mapping being the area where these developments are more striking. 3D geological mapping has a myriad of applications in the domains of basin analysis, geophysics, geostatistics, geothermal and energy resources, etc. A parallel domain of development has been three-dimensional groundwater modelling: regional groun...
