Generate Directional Lights

directional_light(direction = c(0, 1, 0), color = "white", intensity = 1)

Arguments

direction: Default c(0,1,0). Direction of the light.
color: Default white. COlor of the light.
intensity: Default 1. Intensity of the light.

Value

A matrix representing the light information.

Examples
