Shortly after its introduction in 1985, procedural solid texturing became a must-have tool in the production-quality graphics of the motion-picture industry. Now, over fifteen years later, we are finally able to provide this feature for the real-time consumer graphics used in videogames and virtual environments. A texture atlas is used to create a 2-D texture map of the 3-D solid texture coordi...

Texturing an animated fluid is a useful way to augment the visual complexity of pictures without increasing the simulation time. But texturing flowing fluids is a complex issue, as it creates conflicting requirements: we want to keep the texture properties (features, spectrum) while conforming to the underlying flow — which distorts the attached texture. In this paper, we present a new method f...

Low conversion efficiency is still the main limiting factor for current solar-cell technologies. A large portion of the energy loss during solar-cell operation is attributed to optical loss, namely the loss of the incoming light by reflection.[1] To reduce the reflection loss, surface texturing and antireflection coatings are the most-commonly used strategies.[2–4] Surface texturing is able to ...

BACKGROUND A common clinical scenario encountered by an orthopaedic surgeon is a patient with a secure cementless acetabular shell and a failed polyethylene liner. One treatment option is to cement a new liner into the fixed shell. The purpose of this study was to evaluate technical variables to improve the mechanical strength of such cemented liner constructs. METHODS The contributions of sh...

This paper describes a way to perform realistic three-dimensional texturing of ray-traced objects with irregular surfaces. Such texturing has been done in the past with texture mapping, particle systems, or volumetric methods. We propose an alternative to these called a lattice. Lattices work as fast but inexact ray tracers. As long as lattices are used for small objects, though, the inexactnes...

Nowadays the surface texturing has been widely recognized as a usable capability to improve the tribological systems. In this paper, ultrasonic assisted turning (UAT) isperformed to create the micro textures on the flat faces. Micro surface texturing ismade on the Al7075-T6 by the UAT in the face turning process. Then, the influences of cutting speed feed, vibration direction and vibration ampl...

Procedural texturing has been an active research area in computer graphics with some open problems still unsolved (D. S. Ebert, F. K. Musgrave, K. P. Peachey, K. Perlin, and S. Worley, 1998, “Texturing and Modeling: A Procedural Approach,” Academic Press, San Diego). One major problem is on how to estimate or recover the parameter values for a given procedural texture using the input texture im...

Engineering practices and analyses have indicated that surface textures and topography may significantly affect the tribological performance of contact interfaces. Such an influence may be complicated and difficult to be captured with only a few statistic surface parameters. The need for further improvement of the performance and life of machine elements requires that surface topography and tex...
