A set of simulated high-resolution infrared (IR) emission spectra of synthetic cirrus clouds is used to perform a sensitivity analysis of top-of-atmosphere (TOA) radiance to cloud parameters. Principal component analysis (PCA) is applied to assess the variability of radiance across the spectrum with respect to microphysical and bulk cloud quantities. These quantities include particle shape, eff...

Interacting with environments exhibiting the subtle lighting effects found in the real world gives designers a better understanding of the scene’s structure by providing rich visual cues. The major hurdle is that global illumination algorithms are too inefficient to quickly compute their solutions for reasonably sized environments. When motion is allowed within the environment, the problem beco...

Atrium is a popular architectural feature utilized widely by building designers and owners to bring various benefits such as adequate daylight, circulation spaces and surfaces for landscape applications. But atrium problems in tropical climates such as excessive daylight, glare and high temperature, which lead to increase building energy demand, have been reported. Atrium has been used with var...

HDR Radiance Maps have being widely studied in the last years. In this work we recover HDR Radiance Maps from photographs, using only two shots of the same scene exposed diferently. We also recover film response curves to visualize HDR color images as if they were taken with the photographic film. All the operations used to reconstruct the HDR Radiance Map work on image histograms, the presence...

The radiance distribution of light scattered by randomly oriented ice crystals differs fundamentally from the radiance distribution of light scattered by spherical raindrops or by preferentially oriented ice crystals. A formalism for light scattering by randomly oriented crystals is given and applied to four examples, among them the circular 22° halo and the antisolar halospot, the latter being...

We present TensoRF, a novel approach to model and reconstruct radiance fields. Unlike NeRF that purely uses MLPs, we the field of scene as 4D tensor, which represents 3D voxel grid with per-voxel multi-channel features. Our central idea is factorize tensor into multiple compact low-rank components. demonstrate applying traditional CANDECOMP/PARAFAC (CP) decomposition – factorizes tensors rank-o...

The bidirectional reflectance of the ocean is an important parameter in ocean color remote sensing. Model predictions for case-1 waters were compared with measurements over a large range of chlorophyll concentrations (0.1–10 mg m23 Chl, where Chl represents the sum of chlorophyll a and phaeophytin a), but with restricted solar zenith angles. We used the measured chlorophyll concentration and a ...
