Type Declaration

• Optionalname?: string

  Name of the light. Default to ''.

• Optionalcolor?: [number, number, number]

  RGB value for the light's color in linear space. Default to [1, 1, 1].

• Optionalintensity?: number

  Brightness of the light. The units that this is defined in depend on the type of light. point and spot lights use luminous intensity in candela (lm/sr) while directional lights use illuminance in lux (lm/m2). Default to 1.

• type: "directional" | "point" | "spot"

  Declares the type of the light.

• Optionalrange?: number

  Hint defining a distance cutoff at which the light's intensity may be considered to have reached zero. Supported only for point and spot lights. Must be > 0. When undefined, range is assumed to be infinite.

• Optionalspot?: { innerConeAngle?: number; outerConeAngle?: number }

  When a light's type is spot, this property on the light is required.

  • OptionalinnerConeAngle?: number

    Angle, in radians, from centre of spotlight where falloff begins. Must be greater than or equal to 0 and less than outerConeAngle. Default to 0.

  • OptionalouterConeAngle?: number

    Angle, in radians, from centre of spotlight where falloff ends. Must be greater than innerConeAngle and less than or equal to PI / 2.0. Default to PI / 4.0.
