Among the different applications carried out by Downland Partnership in UK, the Westminster Abbey has ordered the development of a mobile phone application, allowing the user to take a super realistic tour into the Abbey.

The application uses the latest 3D scanner technology combined with 3DReshaper to make the surfaced model. This application is one of the first to use laser scanning and 3D modeling for mobile devices (Itunes).

Scans have been made via Leica HDS 6000 and photos using Canon 5D mk2. Surfaces have been generated in 3DReshaper then the meshes have been reduced, edited and followed by texture mapping.

3D modeling of civil engineering structures

The Geneva territory cadastre is now in 3D. Digitalization, modeling and texturing of numerous buildings and civil engineering structures have been done in order to create a GIS in 3D of the Geneva region.

The “service de la Mensuration Officielle” called the MBC Ingéo SA practice for the 3D cadastration of the civil engineer structures placed along the Avanchets neighborhood to Eyrin Cité tram section.

The modeling and most of the texture mapping have been made with 3DReshaper.

Non-contact 3D measurement of an engine with a Romer Absolute Arm SI (scanner integrated). The 3D data are loaded in the Reshaper interface in real time.

Within the exclusive interface between Reshaper and the Absolute SI, the point cloud can be automatically meshed to show detailed features....

3D Model Analysis

Mooring integrity verification

The Welaptega Company provides in-water survey technologies to solve complex underwater problems on floating production systems (offshore oil and gas industry).

In this video, 3 real cases of the Welaptega know-how, associated with 3DReshaper, are presented: a pipeline curvature analysis, a chain link wear analysis, a wellhead model meshing and texture application.
All these components are located from 30 to 100 meters underwater.

3D Modeling

3D Imaging in a karstic cave

Stalagmites are relevant paleo-environmental archives but that imply taking-off and destruction of samples for analyses.

The recent widespread use of terrestrial lidars allows analyses on numerical clones and let imagine increasing detailed analyses of external geomorphology of stalagmites.

A stalagmites forest of the Orgnac’s aven (Ardèche, France) was therefore scanned at a high resolution. The points cloud was then meshed to set a TIN model (Triangular Irregulated Network) with a high density.

An original method was then built up to be able to analyze this 3D model...

3D Control

Containment of Chernobyl Reactor

The containment structure created by the consortium Novarka, is intended for insulating the reactor #4 of Chernobyl. The huge metal structure is designed to ensure the future dismantling of the old shelter and the ruins of the reactor damaged in 1986. Work began in late 2010 and must be completed in 2015.

3DReshaper computes the potential differences between the real building and its CAD model. The dimensions of the containment structure must match with the CAD model (108 meter high for 20.000 tons).

Digitization was performed with a Leica HDS 3000 (terrestrial) and a Riegl LMS Q240 (aerial) 3D scanners.

3D Shape extraction - Section Calculation

Air ducts in the Tunnel of Croix Rousse (Lyons)

As part of maintaining of the air ducts of the Croix Rousse tunnel, one of the oldest city tunnels in France (started in 1939, completed in 1952), 3DReshaper was used to do the 3D meshing, best shape extraction and section calculation.

The ventilation system is in this case transversal: the fresh air goes down the lower part of the tunnel and the fouled air is aspirated in the upper part (air vents are located every 1.28 m).

Digitization was performed with a Leica HDS and a Riegl 3D scanners.
