class voxcity.simulator_gpu.solar.radiation.RadiationConfig

Configuration for radiation model.

albedo_ground

Default ground albedo

albedo_wall

Default wall albedo

albedo_roof

Default roof albedo

albedo_leaf

Tree/leaf albedo (PALM default: 0.15)

n_azimuth

Number of azimuthal divisions for SVF

n_elevation

Number of elevation divisions for SVF

ext_coef

Extinction coefficient for canopy

skip_svf

Skip SVF calculation (use 1.0)

n_reflection_steps

Number of reflection iterations (PALM default: 3)

surface_reflections

Enable surface-to-surface reflections

canopy_reflections

Enable reflection attenuation through canopy

volumetric_flux

Enable volumetric flux calculation

volumetric_n_azimuth

Number of azimuths for volumetric horizon tracing

min_opaque_lad

Minimum LAD considered opaque for volumetric shadows

canopy_radiation

Enable plant canopy radiation absorption (CSF)

canopy_to_canopy

Enable canopy-to-canopy scattering (not in PALM, improves accuracy for dense vegetation where leaves scatter light to neighboring leaves)
