public class SpectralPhotoLighting extends PhotoLighting
A GPU Flux spectral variant of PhotoLighting that uses physically accurate spectral power distributions (SPDs) for sky and sun lights.

Overrides buildSkyDome() and buildSun() to return SpectralSkyDome and SpectralSun instances with preset- appropriate SPDs:

  • Sky: CIE D65 (daylight, ~6504 K) for OVERCAST_DAY and CLEAR_NOON; CIE D50 (warm daylight, ~5003 K) for GOLDEN_HOUR.
  • Sun: blackbody 5778 K for CLEAR_NOON; blackbody 2856 K (warm / incandescent-like) for GOLDEN_HOUR.

Example XL usage with GPU Flux: 

   Axiom ==> new SpectralPhotoLighting(PhotoLighting.CLEAR_NOON);
