Salle de bain by nacimus, rendered with Moonshine

Features

• Binaries
  • offline -- a headless offline renderer
  • online -- a real-time windowed renderer
  • hydra -- a hydra render delegate
• Light Transport
  • Full spectral path tracing
  • Direct light sampling with multiple importance sampling for all lights and materials
• Lights
  • 360° environment maps
    • Sampled via hierarchical warping
  • Emissive meshes
    • Sampled according to power via 1D hierarchical warping
• Materials
  • Standard PBR with metallic + roughness
  • Mirror
  • Glass with dispersion
• Homogeneous volumes
