Local estimations of Monte Carlo method with the object spectral representation in the solution of global illumination [PDF]
Компьютерные исследования и моделирование, 2012 The article deals with the local and double local estimation of the Monte Carlo method for solving the equation of global illumination. The local estimation allows calculating the illumination at any point at the approximation of diffuse reflection ...

A New Model of Solar Illumination of Earth’s Atmosphere during Night-Time
Earth, 2021 In this work, a solar illumination model of the Earth’s atmosphere is developed. The developed model allows us to determine with extreme accuracy how the atmospheric illumination varies during night hours on a global scale.

Illumination invariance and shadow compensation via spectro-polarimetry technique [PDF]
, 2013 A major problem for obtaining target reflectance via hyperspectral imaging systems is the presence of illumination and shadow effects. These factors are common artefacts, especially when dealing with a hyperspectral imaging system that has sensors in the

Comparative Analysis of Real-Time Global Illumination Techniques in Current Game Engines
IEEE Access, 2021 The most important component of photorealism in Computer Graphics is given by a physically correct approximation of the light transport. Besides the direct illumination from light sources, there is an indirect illumination, produced by the reflections of
