Instance Constructors

  1. new Light(attenuateConst: Float = 0.3, attenuateLin: Float = 0.6, attenuateQuad: Float = 0.1)

    attenuateConst

    the constant attenuation factor

    attenuateLin

    the linear attenuation factor

    attenuateQuad

    the quadratic attenuation factor

Abstract Value Members

  1. abstract def apply(pt: Vector3): Vector3

    Calculates the vector of the ray of light that reaches a point.

    Calculates the vector of the ray of light that reaches a point. The length of the vector is the intensity of the light. The direction of the vector is the direction from the light to the point.

    pt

    the point to illuminate

    returns

    the light ray
