We propose a method that uses the point spread function of specular reflection (SR-PSF) to simulate paper gloss. The SR-PSF is defined as the impulse response of specular reflection, which is the distribution of light intensity reflected from microscopic facets on the surface of the paper. In this study, we used a flat sample holder and measured the SR-PSFs of six paper samples, each of which h...

OBJECTIVES This study determined the two-body wear and toothbrushing wear parameters, including gloss and roughness measurements and additionally Martens hardness, of nine aesthetic CAD/CAM materials, one direct resin-based nanocomposite plus that of human enamel as a control group. MATERIALS AND METHODS Two-body wear was investigated in a computer-controlled chewing simulator (1.2 million lo...

for dissemination) This document describes the Gloss software currently implemented. The description of the Gloss demonstrator for multi-surface interaction can be found in D17. The ongoing integration activity for the work described in D17 and D8 constitutes our development of infrastructure for a first smart space. In this report, the focus is on infrastructure to support the implementation o...

A display tool has been developed to perform simulation and three-dimensional rendering of prints in the quest towards achieving improved soft proofing capabilities. It was desired through this 3D simulation that the gloss and surface properties of hard-copy prints be represented on a display, which are absent in current 2D soft proofing workflows. The procedure is described along with the rele...

When we view an object, its appearance depends in large part on specific surface reflectance properties; among these is surface gloss, which provides important information about the material composition of the object and the fine structure of its surface. To study how gloss is represented in the visual cortical areas related to object recognition, we examined the responses of neurons in the inf...

This study evaluated the effects of polishing on surface roughness, gloss, and color of regular, opaque, and enamel shades for each of three resin composites. Two-mm-thick resin disks made with Estelite Σ Quick, Clearfil Majesty, and Beautifil II were final polished with 180-, 1000-, and 3000-grit silicon carbide paper. Surface roughness, gloss, and color were measured one week after curing. Es...
