Normalizes the quaternion. Only normalized quaternions can be used to represent rotations.

Returns 1 / x.

Set values of all lanes to the same value.

Converts this quaternion to a 3x3 rotation matrix. The quaternion must be normalized before calling this function.

Default constructor creates an array of size 0.

const int gFrameSize = 256; const int gFrameSize = 64; const int gFrameSize = 32;

Clamp the first argument to be greater than or equal to the second and less than or equal to the third.

Calculate the coefficients applied to the U, V, and W functions. Because their equations share many common terms they are computed simultaneously.
