Package: skymodelr Type: Package Title: Generates and Samples Realistic Terrestrial Atmospheres Version: 0.3.2 Authors@R: c( person( "Tyler", "Morgan-Wall", email = "tylermw@gmail.com", role = c("aut", "cre", "cph") ), person( "Petr", "Vevoda", role = "ctb" ), person( "Charles University", role = "cph" ), person( "Eric", "Bruneton", role = c("ctb", "cph") ), person( "Lukas", "Hosek", role = c("ctb", "cph") ), person( "Alexander", "Wilkie", role = c("ctb", "cph") ) ) Description: Generates physically based sky environment maps and radiance samples using the spectral Hosek-Wilkie and Prague atmosphere models. Functions write high-dynamic-range 'OpenEXR' domes in latitude-longitude projections, compute per-direction RGB or 55-channel values, and optionally composite time-accurate star fields and moon phases. Features include automatic sun and moon positioning from date, time and location, support for sea-level and high-altitude observers, wide-spectrum coefficients, and multithreaded C++ acceleration for fast, high-resolution output. For model details, see Hosek and Wilkie (2012) , Hosek and Wilkie (2013) , Wilkie et al. (2021) , and Vevoda et al. (2022) .
