This paper highlights lights in a volume-oriented rendering which features a lot of advanced techniques intended to synthesize a highly realistic visual environment for a diverse set of applications. According to proposed method there is almost no need to go higher than 12 bits if the illumination models is computed at a higher resolution because it is then possible to distribute a particular texture over a restricted range of the full pixel dynamic range.
Authors have worked out a nonstationary signal analysis method on an example of research of laser lines. This method disclosed relationship between signal approximation coefficients and geometry signal characterizations (for instance, energy center, moment of inertia). Examples, which is demonstrating an application of this method for exact coordinate determination problem in laser line at displacement compensation in laser imaging are present.
