The Special Issue “Underwater 3D recording and modelling” is focused onchallenges for modeling ways to overcome them in the underwater environment. Given that existing sensors algorithms are not optimized, nor present best possible solutions harsh conditions of submerged environment, new techniques methods need be developed. During last years, we have witnessed groundbreaking technological deve...

We concentrate our efforts on building virtual modelling environments where the content creator uses controls (widgets) as an interactive adjustment modality for the properties of the edited objects. Besides the advantage of being an on-line modelling approach (visualised just like any other on-line VRML content), our approach provides also instant visualisation and an intuitive, graphical edit...

In this paper the investigations of two projects using the terrestrial 3D laser scanning system "CYRAX 2500®" from Leica Geosystems are presented. The CYRAX 2500 is tested in 3D data acquisition and object modelling for industrial as-built documentation and for an architectural application. The major aspects of these investigations were the accuracy of point determination and object modelling, ...

Protein structure is more conserved than sequence in nature. In this direction we developed a novel methodology that significantly improves conventional homology modelling when sequence identity is low, by taking into consideration 3D structural features of the template, such as size and shape. Herein, our new homology modelling approach was applied to the homology modelling of the RNA-dependen...
