VITRAIL : Acquisition, Modelling and Rendering of Stained Glass

Martin Vetterli, Paolo Prandoni, Loïc Arnaud Baboulaz, Niranjan Thanikachalam

Stained glass windows are designed to reveal their powerful artistry under diverse and time-varying lighting conditions; virtual relighting of stained glass, therefore represents an exceptional tool for the appreciation of this age old art form. However, a ...

Image Based Relighting of Cultural Artifacts

Niranjan Thanikachalam

By incorporating computational methods into the image acquisition pipeline, computational photography has opened up new avenues in the representation and visualization of real world objects in the digital world. For example, we can sample a scene under a f ...

A Monolithic Micro-Tensile Tester for Investigating Silicon Dioxide Polymorph Micromechanics, Fabricated and Operated Using a Femtosecond Laser

Yves Bellouard, Christos Edouardos Athanasiou

Mechanical testing of materials at the microscales is challenging. It requires delicate procedures not only for producing and handling the specimen to be tested, but also for applying an accurate and controlled force. This endeavor is even more challenging ...

Multilevel Micro-Structuring of Glassy Carbon for Precision Glass Molding of Diffractive Optical Elements

Hans Peter Herzig, Toralf Scharf, Karin Prater

A consumer market for diffractive optical elements in glass can only be created if high efficient elements are available at affordable prices. In diffractive optics the efficiency and optical properties increases with the number of levels used, but in the ...

Surface Chemistry of Calcium Aluminosilicate Glasses

Ruben Anton Snellings

The surface chemistry of synthetic calcium aluminosilicate glasses exposed to aqueous solutions of varying pH was described using zeta potential measurements and batch surface titrations. Element release and proton consumption were measured to characterize ...

Edge strength model for glass based on the mirror zone depth

Pieter Christian Louter

A reliable assessment of the edge strength becomes an important issue when designing structural glass elements in buildings. However, in the literature the edge strength of glass, dependent on the edge quality, is not well documented. Therefore, in this st ...

Strength of glass determined by the relation of the critical flaw to the fracture mirror

Jean-Paul Lebet, Maria Lindqvist

Tensile strength of structural glass elements is highly influenced by flaws. For this paper, the study concentrates on the fracture origin i.e. the critical flaw, situated at the edge of a glass element. In the current study the influence of two different ...

Application of hybrid glass-timber elements in architecture

Pieter Christian Louter, Manuel Santarsiero, Paul Ehret, Philipp Eversmann

The following paper explores the application of hybrid timber-glass elements on semi-continuous architectural structures. The use of glass as a structural material opens multiple fields of investigations. Beyond structural matters and safety issues, archit ...
