3D Modelling of Fez

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)

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 Application for BIM Projects

OS Model Builder is a recently launched visualisation tool that can support projects, including Level 2 BIM activities, and was developed to save the construction industry and its clients’ time and money when planning future projects. OS Model Builder is the result of an exciting new collaboration between Cadline and Ordnance Survey (OS) to provide Autodesk Infraworks 360 customers with a single source of Great Britain’s most accurate and up-to-date collection of geographic data, all presented in a pre-configured CAD-ready file that can be used to create 2 and 3D building or infrastructure models in minutes rather than days or weeks. The application... (read more)

Investigation of 3D Modelling Techniques

3D Modelling and Web-based Visualisation of Cultural Heritage Objects
The rapid developments in the fields of photogrammetry, laser scanning, computer vision and robotics provide highly accurate 3D data. 3D models that can be created from such types of data are extremely effective and intuitive for present-day users who have stringent requirements and high expectations. Depending on the complexity of the objects for the specific case, various technological methods can be applied. Read on for a comparison of three technologies, based on real projects, including an assessment of their suitability for web-based visualisation of numerous objects of interest.

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 Modelling from RGB Images

FOVEX Measure 3D is a combination of a super-fast high-resolution 360° panorama camera and innovative software that allows accurate measurement and CAD modelling directly within the images. FOVEX Measure 3D allows significant savings in field and office work, thereby increasing productivity. The technique is to be presented at Intergeo, taking place from 9 to 11 October 2012 in Hanover, Germany. After measuring an object in two images, its shape can be modelled by connecting points directly in the software. Therefore, the CAD model can be completed within the FOVEX software directly and the model as a whole can be exported... (read more)

3D Modelling of Shukhov Tower

Using Laser Scanning to Model a Russian Radio Tower
The 90-year-old Shukhov Tower in Moscow, Russia, is not only in a state of severe disrepair but the 150m-high steel construction is also under-documented. To support restoration initiatives or, in case of unexpected collapse, to enable the tower to be observed virtually, the authors carried out ground-based laser scanning using seven scan positions to create a detailed 3D model. Built in the period from 1919 to 1922, the radio tower at Shabolovka is an icon of Soviet broadcasting and a world-renowned monument of Russian avant-garde architecture. Today it is called Shukhov Tower after its designer V.G. Shukhov (1853-1939), an outstanding... (read more)
