====== PragueSkyModel ======

Prague Sky Model (2021) — dataset-driven full-spectral sky light.

Implements the sky model by Wilkie et al. (2021) and Vévoda et al. (2022), presented in //"A Fitted Radiance and Attenuation Model for Realistic Atmospheres"//. 

===== =====

The model covers:

  * Solar elevation from -4.2° to 90°
  * Visibility (meteorological range) from 20 km to 131.8 km
  * Observer altitude from 0 km to 15 km
  * Ground albedo from 0 to 1
  * Full spectrum: 280–2480 nm (ground-level dataset)

**Dataset required:** this model requires an external dataset file available from the Charles University Prague sky model page. The ground-level dataset is approximately 103 MB. Set the path via ''setDatasetPath(String)''.
