Lighting (.lighting)

point_lighting

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

Bases: NamedTuple

environment: World

lights: list

infinigen2.lighting.point_lighting.floating_colored_lights_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.
