Digital objects and digital surfaces are isothetic structures per se. Such surfaces are thus not adapted to direct visualization with isothetic quads, or to many geometry processing methods. We propose a new regularization technique to construct a piecewise smooth quadrangulated surface from a digital surface. More formally we propose a variational formulation which efficiently regularizes digi...

We present a method relying on expansion textures to add details such as folds on a surface. The user paints the expansion attributes on the surface (amount and direction of expansion, wavelength and regularity of folds), using either interactive or procedural tools. The modeling system generates the folds by calculating the new surface equilibrium. Results show that this tool allows CG artists...

Crystalline silicon thin film (c-Si TF) solar cells with an active layer thickness of a few micrometers may provide a viable pathway for further sustainable development of photovoltaic technology, because of its potentials in cost reduction and high efficiency. However, the performance of such cells is largely constrained by the deteriorated light absorption of the ultrathin photoactive materia...

Usage of a projection system to display large screen images is still relevant in the midst of LED-based display increasing popularity. This is due to that the system itself is a mature technology, reliable and cheaper than the LED counterpart. While various methods had addressed the projection problems on curve surface, projecting image on jagged like surface (zero order geometric continuity) h...

Due to the progress in computers and sensors development the number of virtual reality application (VR) grows significantly. Different sensors and techniques such as laser range finders, still and video cameras, mechanical digitizers are used to obtain spatial object coordinates for producing 3D models. The two main requirements to the produced model are the accurate geometry reconstruction and...
