This article presents an inexpensive approach to provide (s,t) texture coordinates of a spline surface that mitigates texture compression and stretching artifacts. It employs a chordlength approximation based on the original spline surface parameterization.

All objects have a surface roughness which manifests itself as small forces when objects slide under load against each other Simulating this roughness hap tically enriches the interaction between a user and a virtual world just as creating graphical textures enhances the depiction of a scene As with graphical textures a major design constraint for haptic textures is the generation of a su cient...

A maskless plasma textu~ring technique using Reactive Ion Etching for silicon solar cells results in a very low reflectance of 5.4 % before and 3.9 % after SiN deposition. A detailed study of surface recombination and emitter properties was made, then solar cells were fabricated using the DOSS solar cell process. Different plasmadamage removal treatments are tested to optimize low lifetime sola...

Texture mapping is a common method for combining surface geometry with image data, with the resulting photorealistic 3D models being suitable not only for visualization purposes but also for interpretation and spatial measurement, in many application fields, such as cultural heritage and the earth sciences. When acquiring images for creation of photorealistic models, it is usual to collect more...

This paper presents a new ultrasonic servo control drive for electro discharge texturing system industrial applications. The new drive is aiming to overcome the current teething issues of the existing electro discharge texturing system, servo control drive level of precision, processing stability, dynamic response and surface profile of the machined products. The new ultrasonic servo control dr...

The visualization of huge 3D objects becomes available on common workstations thanks to highly optimized data-structures and out-of-core frameworks for rendering. However, the editing, and in particular, the texturing of such objects is still a challenging task, since usual methods for optimized rendering are not easily amenable to interactive modification. In this paper, we introduce the idea ...

Amorphous silicon/crystalline silicon (a-Si/c-Si) micromorph tandem cells, with best confirmed efficiency of 12.3%, have yet to fully approach their theoretical performance limits. In this work, we consider a strategy for improving the light trapping and charge collection of a-Si/c-Si micromorph tandem cells using random texturing with adjustable short-range correlations and long-range periodic...

I would like to thank Mr Curtis and Dr Klykken for their insightful comments regarding textured implants. The use of the trademark “Silastic” was incorrect in the discussion of implant covers. The correct term that should have been used is “silicone elastomer.”We did not intend to implicate Silastic elastomer (Dow Corning, Midland, MI) in the development of anaplastic large-cell lymphoma, and w...
