This paper proposes a new approach for paint appearance simulation. Coatings color and appearance change significantly according to lighting and observation conditions. The aim of this study is to propose both real time and accurate solutions for painted surface simulation. To solve real time constraints, we have chosen to simulate the paint appearance thanks to textures. Each texture represent...

Most present-day interactive paint applications lack the means of adequately capturing a user’s gestures and translating them into realistic and predictable strokes, despite the importance of such a mechanism. We present a novel brush design that adopts constrained energy optimization to deform the brush tuft according to the user’s input movement. It incorporates bidirectional paint transfer a...

This study explores how paint affects the specific airflow resistance and visual appearance of nonwoven scrims used on acoustical ceiling tile. Nine different scrims are included. Each scrim is finished with two application rates of paint. The specific airflow resistance is measured by the ASTM C522 method. The painted samples are also scanned and the images processed by ImagePro software to ch...

Given its vapor pressure, toluene tends to partition to the atmosphere. Automobile emissions are the principal source of toluene in ambient air, with levels fluctuating in proportion to automobile traffic. Toluene can also be a common indoor contaminant, and indoor air concentrations are often several times higher than outside air. This is likely due to release of toluene from common household ...

A 220 nm bandwidth supercontinuum source in the two-micron wavelength range has been developed for use in a Fourier domain optical coherence tomography (FDOCT) system. This long wavelength source serves to enhance probing depth in highly scattering material with low water content. We present results confirming improved penetration depth in high opacity paint samples while achieving the high axi...

We propose a paintmeter for noncontact and remote monitoring of the thickness and drying progress of a paint film based on the time-of-flight measurement of the echo signal of a terahertz (THz) electromagnetic pulse. The proposed method is effectively applied to two-dimensional mapping of the painting thickness distribution for single-layer and multilayer paint films. Furthermore, adequate para...
