We present a novel algorithm for deforming a locally smooth polygonal mesh by sliding its vertices over the surface. This sliding deformation creates the visual appearance of texture animation without requiring an explicit global surface parameterization or the overhead of storing texture coordinates. The proposed deformation algorithm can also be employed to slide vertices over the surface to ...

Biometrics-based technologies in the area of identity management are gaining increasing importance, as a means of establishing non-falsifiable credentials for end users. However, in the three-way tug-of-war between convenient, unobtrusive data collection (required for user acceptance), accuracy in results (required for justifying deployment), and speed (required for widespread use in practice),...

Image-based object modeling enables us to compose photorealistic images of modeled objects for various rendering conditions (viewpoints/light directions, etc.) However, it is very challenging to acquire a huge number of object images for all combinations of capturing parameters and to then handle the resulting huge data sets for the model. In this paper, we present a novel modeling method for a...

Introduction: Understanding the formation processes of deformation features originating in association with viscous flow on Mars, including lineated valley fill (LVF), is a key component in the estimation of climate conditions on Mars during its recent history [1-3]. Previous work has focused on estimating temperature conditions from temperature-dependent flow laws [e.g., 1-2]. In order to extr...

Neutron diffraction has been used for engineering applications for nearly three decades. The basis of the technique is powder diffraction following Bragg’s Law. The measured diffraction patterns provide information about internal strains, texture and microstructure, which can be deduced from the peak positions, peak intensities, and peak widths, respectively. Most structural materials are aniso...
