Function refract

Calculates the refraction vector of two vectors.

refract(
    vect1: ChalkboardVector,
    vect2: ChalkboardVector,
    refractiveIndex: number,
): ChalkboardVector
Parameters
- vect1: ChalkboardVector
  The first vector (the incident vector)
- vect2: ChalkboardVector
  The second vector (the normal vector)
- refractiveIndex: number
  The refractive index of the refractive medium
Returns ChalkboardVector
