Lighting (.lighting)

point_lighting

class infinigen2.lighting.point_lighting.ColoredLightsResult(environment, lights)

Bases: NamedTuple

Fields: environment: World; lights: list

infinigen2.lighting.point_lighting.lights_floating_colored_rand(

...,

) → ColoredLightsResult

Random-colored point lamps scattered in bbox against a black world, so a demo object reads as lit purely by the colored lights.
