3D Modelling of Castles

Integrating Techniques for Detail and Photo-realism
Three-dimensional documentation of heritage buildings is important for conservation, restoration and education. When it comes to complex architectural structures such as castles, no single modelling technique is capable of yielding cost-effective, highly detailed and accurate photo-realism. The authors demonstrate how integration of multiple techniques brings resolution.<P> Castles are unique and fascinating structures of complex architecture the style of which has evolved over centuries. Three-dimensional modelling aims at capturing all geometrical detail, both exterior and interior, and representing these features with high-resolution triangular meshes for accurate documentation and photo-realistic visualisation. Modelling complex and large-scale architecture requires the integration of multiple techniques,... (read more)

3D Modelling of Fez

A Model From Aerial/Terrestrial Imagery and Topographic Maps
The ancient imperial city of Fez, Morocco, is an important tourist attraction and has been listed as a UNESCO World Heritage Site since 1981. The layout of the city is complex, which presents challenges in terms of 3D modelling. Here, the authors discuss a pilot aimed at creating a 3D model of Fez using topographic maps and aerial and terrestrial imagery. Overlapping 1:4,000 aerial images were used to create a digital surface model (DSM) and orthoimages. Orthoimages and topographic maps were used to manually delineate the footprints of buildings, roads, rivers and suchlike. Terrestrial imagery of single buildings from multiple... (read more)

Reducing 3D Modelling Time

A new product in the AVEVA Plant portfolio is AVEVA Laser Modeller, a 3D laser scanning software solution that can reduce by up to 50% the time for intelligent 3D modelling of brownfield facilities. Over the past 12 months, key customers have played a role in the development and testing process of this new product. The application facilitates traditional costly techniques for converting laser scan data into an intelligent 3D model to become obsolete, according to Bruce Douglas, senior VP Marketing & Product Strategy of AVEVA. He continues saying that AVEVA Laser Modeller changes the fundamental ground rules by adding... (read more)

Detailed 3D Facade Modelling

A new solution from GTA (Germany) and Procedural offers more 3D detail in modelling of large databases of real-world building data. Special focus is set to add depth to the facade, as well as roof details. CityEngine imports 3D buildings generated automatically using GTA’s software solution Tridicon 3D, transfers detailed tridiconTM3D façade description to CityEngine building parameters and generates rich and visually pleasing procedural 3D buildings.     In addition to its highly efficient modelling tools, there is GTA’s 3D database with more than 175 European cities and 5.400 km² real-world building data available. Highlights are the 3D city model... (read more)

End-to-end 3D Modelling Solution

ClearEdge3D, USA, has officially launched EdgeWise Plant 4.0, with numerous major new features and enhancements that have created one of the fastest end-to-end pipe modelling solutions on the market. The software automates the 3D modelling of complex process plant facilities, cutting up to 85% of labour from the modelling workflow. Robert Greenhalgh, Ramboll Oil & Gas, used the software on a recent North Sea offshore project. They reduced their 3D modelling time substantially with EdgeWise Plant 4.0. Building standard pipe fittings on top of the powerful automated tools makes 4.0 a complete pipe modelling package, he said. The new features... (read more)

3D Urban Modelling Seminar, UK

A seminar on 3D urban modelling and ways in which it can be implemented into your working life is being organised by aerial photography company Getmapping. Held at Bath Spa University (Bath, United Kingdom), on Thursday 19th April 2007, the one day seminar will provide an operational insight into the potential of 3D urban modelling and its uses in the modern work place. Discussions and demonstrations will focus on the growing benefits of 3D modelling, the difference between data sets currently available, a review of the tools currently accessible for analysing data and the new storage/streaming technologies that can be...

3D Cadastre Modelling in Russia

Assessment of Added Value
Russia has the intention to develop and implement a 3D cadastre. A Russian-Dutch project on 3D cadastre modelling assessed the added value of a 3D cadastre. At present, the system of state cadastre and real estate registration in the Russian Federation is based on the 2D representation of objects including land parcels, buildings and structures. However, the current approach does not cover all situations of the real 3D world. Examples of such situations impeding cadastre and rights registration are: multilevel complexes, intersections of various objects in space, underground and elevated engineering networks, etc. The project included prototype development and a...

Air Pollution Modelling with 3D Visualisation

UK-based environmental engineering company Cambridge Environmental Research Consultants (CERC) has been using the TatukGIS Developer Kernel (DK) ActiveX edition since 2007 to develop the GIS mapping module for its ADMS air pollution modelling software. The mapping module developed from the TatukGIS DK, called ADMS Mapper, is used to visualise and edit input data for the ADMS modelling software. The Mapper can render pollutant concentrations output from the ADMS model. Before ADMS Mapper became available, users of ADMS had to buy third-party GIS software such as ESRI ArcGIS or MapInfo to visualise their modelling scenarios. ADMS is used by hundreds of people...
