tryNormalizeInPlaceWithAreaWeight Method

Normalize the ray direction in place.

• If parameter a is clearly nonzero and the direction vector can be normalized,
  • Save the parameter a as the optional a member of the ray.
  • Normalize the ray's direction vector.
• If parameter a is nearly zero,
  • Set the a member to zero.
  • Set the ray's direction vector to zero.

tryNormalizeInPlaceWithAreaWeight(a: number): boolean

@returns true if a is nonzero and normalization was successful. Otherwise, return false.

Returns - boolean

true if a is nonzero and normalization was successful. Otherwise, return false.
