To reproduce the observed spectra and light curves originated in neighborhood of compact objects requires accurate relativistic ray-tracing codes. In this work, we present Skylight, a new numerical code for general-relativistic ray tracing radiative transfer arbitrary space-time geometries coordinate systems. The is capable producing images, spectra, from astrophysical models as seen by distant...

Vegetation rendering and animation in real-time applications still pose a significant problem due to the inherent complexity of plants. Both the high geometric complexity and intricate light transport require specialized techniques to achieve high-quality rendering of vegetation in real time. This thesis presents new algorithms that address various areas of both vegetation rendering and animati...

We present the first high-resolution maps of Rayleigh behavior in clear and cloudy sky conditions measured by full-sky imaging polarimetry at the wavelengths of 650 nm (red), 550 nm (green), and 450 nm (blue) versus the solar elevation angle thetas. Our maps display those celestial areas at which the deviation deltaalpha = /alphameas - alphaRyleigh/ is below the threshold alphathres = 5 degrees...

Polarimetry, which seeks to measure the vectorial information of light modulated by objects, has facilitated bionic geolocation and navigation applications. It is a novel promising field that provides humans with remote sensing tool exploit polarized skylight in similar way polarization-sensitive animals, yet few in-depth reviews exist. Beginning biological inspirations, this review mainly focu...
