1.25.1 Light Sources
Each light source that should emit global illumination should have an energy statement (just as for caustics). Each light source can also optionally have a globillum photons statement to specify how many photons should be emitted (similar to caustic photons for caustics). The default value is 100000 globillum photons. For example:
light "globillum-light" "physical_light" (
"color" 700.0 700.0 700.0
)
origin 20.0 30.0 -40.0
energy 700 700 700
globillum photons 100000
end light
"color" 700.0 700.0 700.0
)
origin 20.0 30.0 -40.0
energy 700 700 700
globillum photons 100000
end light
