Described herein is a computer-implemented method for simulating texture features of a n-layer target coating, the method including at least the steps of: a) providing known real geometrical properties and known individual ingredients with known real material properties; b) modelling the n-layer target coating in a virtual environment; c) virtually tracing rays of light from one or more light sources towards an aim region defined on a surface of the n-layer target coating; d) virtually collecting rays of light that interacted with the n-layer target coating; e) virtually determining, at least one of an angular, a spectral and a spatial distribution of intensity of the rays of light re-emitted from or reflected by the n-layer target coating; and f) evaluating the determined distribution(s) of intensity and outputting, by an output device, at least one image based on the evaluation.

Method and device for identifying interference pigments in a coating

In a process for recognizing organic substances in solids by measuring the spectram of the radiation which is reflected or transmitted, radiation with a wavelength between 2-4 &mgr;m is used and, for radiation of solids, unmodulated radiation is used. The radiation source should have an output of at least 50 W and the distance between the illumination optics from the solid being investigated should be at least 10 cm. Recognition is based on absorption bands of the extended oscillations of C&mdash;H bonds and sometimes the presence of absorption bands of N&mdash;H bonds. Broad band radiation is preferable for radiation of the solids, and the reflected or transmitted radiation is directed through a narrow band filter with adjustable transmission frequency. This can be advantageously formed with an acousto-optical filter.
